After making slides of canada balsam in which the tests are protected by supporting the cover slips by small tabs of various diameters and thicknesses, other problems emerged; When near transparency finally emerges, it becomes evident that the tests need to be far cleaner than for dry mounting, so an extra cleaning stage needs to be introduced. The first effort with hydrogen peroxide might be helping but long term immersion will be needed at the very least.I hope more lucid images will emerge.

are to be found throughout the world as fossils in the sedimentary rocks of
marine origin. They are an important part of the structure of many hills and
mountains around the world, like Ballard Down. A small block of chalk can
contain millions of tests of Foraminifera.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify; text-indent: 36.0pt;">
<span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">What is rarely
appreciated is that they also flourish today as living creatures in the open
sea as part of the plankton and the estuarine areas of river as at Poole. Foraminifera are actually closely related to
the Amoeba of our school text books but they grow a shell like structure called
a test to protect themselves from the many hungry creatures of the seas. There
are no organs and these animals belong to the Protista: the simplest and
earliest of creatures to appear on Earth. The tests are made of various types
of chalk (calcite). Some species seem to be almost transparent, being
constructed of crystalline calcite, but others seem to be paved with porcelain
like chalk but in the river mouths where there is less chalk dissolved in the
water, they are protected by particles of sand or debris bonded onto a covering
of a chitin-like material. These are called arenaceous species. The
Foraminifera are clearly masters of adaptation as well as being climate
indicators. Generally the white tests are noteasy to find because they are very
small but in deposition areas they can be found en masse, usually mixed with
black sea coal from industrial spillage and ship wrecks. This gives these sites
a black and white banding which</span><span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-fareast-language: EN-GB;"> </span><span style="font-family: "Times New Roman","serif"; font-size: 12.0pt;">is easy to spot
(See above Right). In Swanage Bay an
area can be discovered between the Mowlem building and the Public Hard at low
tide. Washing, sieving, drying and floatation in clean, fresh water all help
to improve the sample.<o:p></o:p></span></div>

Fleet, there are local deposits within Poole Harbour near the Salt
marshes at Arne and Redhorn Quay where they lie almost unseen, amongst the
small washed up shells. </span><span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-ansi-language: EN-GB; mso-bidi-language: AR-SA; mso-fareast-font-family: Calibri; mso-fareast-language: EN-GB;">The ornamental tests of these invertebrates are

significant scientific interest.</span><span style="font-family: "Times New Roman","serif"; font-size: 12.0pt; mso-ansi-language: EN-GB; mso-bidi-language: AR-SA; mso-fareast-font-family: Calibri; mso-fareast-language: EN-US;"> The two illustrations above, clearly show

Quite often one change leads to a complete change of direction. I have been aware of the deposition of Fresh Water tests of testate amoeba in Swanage bay for several years but have rather overlooked them as an object of interest. </div>

After several years of Dry mounting I have moved over to aspects of Mounting in Canada Balsam. and this has enabled photography using traditional methods such as Bright field, Dark field, and photography of arenaceous tests of foraminifera in polarised light.</div>

</div>
<div class="separator" style="clear: both; text-align: left;">
More recently I have tried polarised light not only at full extinction of direct light but also when using various Victorian selenite plates. These effects are rather unnatural looking and much less sharp but never the less they are quite compelling. I include my first effort as the coloured image above. The less colourful one below is a test from several years ago shown for comparison.</div>

<span style="font-size: 12pt;"><span style="font-family: Calibri;"><span style="mso-spacerun: yes;"> </span>Although More frequently Mounted dry, the mounting
in Canada Balsam has surprising results. At the Turn of the centuary in 1900
Joseph Wright the clear leader of the Belfast “School” of Forams, discovered
that Canada Balsam mounting improved the clarity of vision and was particulary
lucid for arenaceous tests. He makes a clear statement in his account of the
Foraminifera of <span style="mso-spacerun: yes;"> </span>Rathlin Island.</span></span></div>

most distinctly the arrangement of the chambers throughout the entire test. I
have examined In this way about 150 from dredgings taken off the Irish coast,
including These Rathlin specimens, with a large number of fossil specimens from
the Chalk of Co, Antrim; also the only perfect specimen, which I had of the variety
fistulosa, Brady, from Raine Island Torres Straits 166 fathoms. In all Cases
both the recent and fossil specimens when perfect had the early chambers

<span style="font-size: 12pt; line-height: 115%;"><span style="font-family: Calibri;">However those species
constructed of crystalline calcite do become quite transparent when mounted in
Canada balsam. The full beauty of the three dimensional spiral then becomes
both evident and optically enhanced. The tests must be much cleaner than
normally used for dry mounting and up to three days immersion in an open vessel
of hydrogen peroxide may be required followed by washing in a fine sieve of pure
water. The initial problem however, is ridding the mount of air bubbles before
mounting commences. The tests may be laid as a small central strew or equally
well they may be laid in a geometric or taxonomic array, depending upon the
quality of material available. The tests can be secured to the glass with the
Gum tragacanth more traditionally used for dry mounting and when dry, the
slides can be immersed in toluene overnight in a Coplin Jar half filled with
the solvent. Quite often vacuoles of air are trapped and unable to escape from
the natural apertures within the test, so before mounting, the<span style="mso-spacerun: yes;"> </span>need to be examined under the microscope.
Species of the Lagena genus only have one small aperture so the slide may need
to be inverted several times over two to three days. When the expulsion of air
is complete, the slide can be laid on a hot plate and two drops of Canada
balsam applied with a pipette and a coverslip laid. Since the tests are quite
thick and brittle compared to other micro-organisms the slip must be applied
without pressure and the simplest and best support is the use of three
peripheral disks of around 0.5mm thickness 1.5mm diameter. The disks should be
bonded to the coverslip before mounting using glass bond in sunlight followed
by washing in toluene and drying with paper tissue before use. The cutting tool
for these is flat nosed pliers drilled out for a piston on one side and a complimentary
hole on the other These tools are actually available for the amateur Jewellery
trade. Any burrs may be rubbed down on fine emery paper. Suitable brass or
aluminium sheet from model shops can be purchased in various thicknesses but
having been produced in the USA the measurements then tend to be imperial
rather than metric. A vernier gauge is also a useful tool for this work of
course. The space afforded by the three small discs also enables spontaneous bubbles
to escape quite freely during the drying process. After several days of
hardening the surplus balsam can be scraped away with a scalpel and the work
can be ringed and protected with black shellac in alcohol and dried. Suitable

This is a description of just such a method from that age, which is equally suitable for use in dry mounting as in Canada Balsam. </p> <p class="western" style="margin-bottom: 0cm"><br /></p> <p class="western" style="margin-bottom: 0cm">Is begins with having a sieved washed sample of Radiolaria that has first been washed in acid and looks clean and bright in good light, before mounting.</p> <p class="western" style="margin-bottom: 0cm"><br /></p> <p class="western" style="margin-bottom: 0cm">Preparation is as with most things the key to success. Quality 3X1” glass slides need to be well washed and quality Gum Tragacanth as well as a ringing table is required.</p> <p class="western" style="margin-bottom: 0cm"><br /></p> <p class="western" style="margin-bottom: 0cm"><u><b>Mountng in Resins such as Canada Balsam or Eukit</b></u>.</p> <p class="western" style="margin-bottom: 0cm">The Gum Tragacanth solution must first be prepared . I use the lid of the gum jar as a painters pallet and add one very small portion of gum to a large pool of distilled water on the lid. When the gum is fully dissolved there must be no blobs of mucilage visible. If there are any blobs, use a pipette to suck them up and add more water, until nothing is visible in the fluid.</p> <p class="western" style="margin-bottom: 0cm">The clean 3X1” slide is placed on the ringing table and a little paintbrush is used to run a circular pool of gum water onto the centre of a rotating glass slide. Check that the circular disk of gum/water is stable, sometimes it prefers to run off into pools. Then perhaps the suface is contaminated and an alcoholic wipe might help.When the liquid is correct, dry it off with gentle heat until quite dry. One should be able to see a dried up but complete feint disk of dry gum . If it is too white and prominent, wash it off and try again with less gum or more water. Remember, that the dried up disk of gum will become the same diameter as the completed strew of Radiolaria.</p> <p class="western" style="margin-bottom: 0cm">Then make sure the slide is cool . Here a cold plate from a fridge might help, and breath on it. Ones breath should condense on the glass in droplets but the disk of gum will become slightly liquid, as it absorbs moisture. Then pour the shells from a Petri dish onto the central disk quite thickly and then invert the slide smartly over the Petri dish so that most of the loose shells return to the dish. Tap the glass to make them fall. Then use the warmth of a lamp to dry the thing off fully and again invert the slide over the Petri dish so that the shells that landed on the liquefied gum remain, but those that landed on damp glass now fall, having dried out. One should now be looking a a clean disc of Radiolaria surrounded by clear glass. Make sure that the whole slide is dry by heating under a lamp. </p> <p class="western" style="margin-bottom: 0cm">Then a resin like Canada Balsam thinned with a little Xylene is dropped on the middle to help expel the air from the shells. Then place a drop of thicker Balsam or other resin over the shells and lower a cover slip.</p> <p class="western" style="margin-bottom: 0cm">This may seem to be quite a performance for a tiny circle of Radiolaria, but it will be worth the effort.<u><b> </b></u>The resin may then be dried off with heat in the usual way, and the slide labelled.</p> <p class="western" style="margin-bottom: 0cm"><u><b>Dry Mounting</b></u></p> <p class="western" style="margin-bottom: 0cm">Dry Mounts may be constructed in a similar manner but first an aluminium ring must be cemented to the glass and a black background must be laid and dried . More care is needed in any heating or the paint may be damaged. The circle of gum-water can then be laid using the ringing table. When this is successful the same procedures can be followed but without the Canada Balsam or other resin of course. This same system can also be used to renovate a very old slide that has through the ravages of time become thoroughly unsuitable for use. The method itself was I know learned from a very old book but I am afraid that I have long forgotten the reference or the original author of the idea.</p><p class="western" style="margin-bottom: 0cm"> Image to follow next weekend, hopefully BD</p><p class="western" style="margin-bottom: 0cm"><br /></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6142755590749587922.post-13000366070194040032010-11-09T02:40:00.000-08:002010-11-09T02:50:51.659-08:00Two Species of Lagena<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhnnwNHzOS5xN2rrX-E8FIkIrgHXBuWbsgCQBLPCXUdnfgV89AIPlf3zbLFfdv2d5CFNuq9_j_t0_YTgN5gHnqmF7Or5Qz9TPgYjHl6hacUhaVdlI5wPZwxEbaZFljwXPd6f1vBKVgTAak/s1600/photos.jpeg"><img style="TEXT-ALIGN: center; MARGIN: 0px auto 10px; WIDTH: 317px; DISPLAY: block; HEIGHT: 320px; CURSOR: hand" id="BLOGGER_PHOTO_ID_5537498442836100418" border="0" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhnnwNHzOS5xN2rrX-E8FIkIrgHXBuWbsgCQBLPCXUdnfgV89AIPlf3zbLFfdv2d5CFNuq9_j_t0_YTgN5gHnqmF7Or5Qz9TPgYjHl6hacUhaVdlI5wPZwxEbaZFljwXPd6f1vBKVgTAak/s320/photos.jpeg" /></a> At the moment I am trying to complete an illustrated booklet on the Foraminifera from my digital pictures and I have just been distracted by these two species of lagena.

Never the less its really surprising what sort of a number one can come up with, but it is just these figures no matter how inaccurate, that engage and surprise the general public.How do we find an average when there are so many eroded tests to sample ?<br /><br /><br />I have just taken a typical surviving test mounted in a canada balsam strew that is neither too small nor too large by observation. The initial measurements were taken with a Beck eyepiece graticule graduated in parts of a mm. I shrank and expanded the image until it was exact according to my record through the microscope.<br />Since the chambers of the test are quite globular, I measured the radii of each chamber and calculated the volume of each, using the formula (<span style="color:#3333ff;">Radius cubed times PI times 4/3)</span> ; the formula for the volume of a single globe. The results were then added together. My selected "average" test made 0.00044107 cu mm which is pretty small .<br /><br />This was then divided into the volume of the 15cm block cube which is hopefully 3,375,000 cubic mm. The result is rather nicely 7,651,846,645 which is fascinatingly enough very nearly the human population on Earth not so long ago. I think we are currently way past this figure and well over the 8 billion. This means that the calculation for the whole of Ballard Down would need a considerable amount of paper, and my old computer would certainly blow a fuse in the process.<br />When I consider the effect of potential inaccuracies on this figure it can more probably become greater than smaller.<br /><br />I fully appreciate that numerous other and perhaps better methods can be used to arrive at a figure. I tried several alternatives but came back to the above with all its faults.

I should have spent more time writing about the point. <br /><br />that was the really the point of the aticle I suppose.!!!................<br />I have to write that at first I could not find a tube that was 1mm external so I used 1.5mm diam. and had to shape the point by rotating it when it just protruded from my mark one version . I used a combination of a fine triangular file and very fine sandpaper to make a blunt point of about 0.3mm diam. at the end but the very end was flat and burnished flat and then painted with Matt black.<br />The relatively. large forams like Elphidium I glued on the round end with water based Gum tragacanth so that any part of the periphery could be imaged. by rotation .====Then I decided that a flat platform was also a good stage for angular shots of apertures .so I filed one side flat to create a flat stage 2mm long which bit into the end of the cylinder to a width of 0.3mm. I had to buy a brass vernier measure .<br /> When I found my 1mm external hollow brass tube in Holland the diameter of the insert was 0.3mm and that was the right size without treatment except when I wanted the inclined stage. All the measurements were based on my wanting to look at the Foraminifera tests. and in particular those of +_ 500um diam.<br /> <br />So briefly Gumming with Gum Tragacanth on the end of the 0.3mm insert rod is how I now do it.<br /><br />Centralisation on the end so would be trial and error whilst under the microscope as the tests are drying off..<br /><br /><br />Its up to you folk to develop it. I can see that some with a large(ThicK) mechanical finger on thir stage (ie the Clip)may need another slide glued underneath but that is not a problem. Also for reflected light only then a layer of paint underneath might look neater and avoid little glares!.<br /><br />Also Please read info on the supply of 1mm hollow tubes<br />NOTE for integration into the text or at the end.<br /><br /> A SUPPLY OF 1MM HOLLOW BRASS TUBES.<br />At first I could not find any tube less than 1.5mm in diameter in the<br />UK. I had to use thicker glass up to 1.5mm but it<br />was much more difficut to cut neatly.<br /><br />Even on line scanning on US sites, I found nothing; they still seem to<br />be using imperial measure anyway. Then I began to look at the EU and<br />sure enough there was the 1mm I was looking for on a Dutch site for<br />hobbyists.<br /><br />http://www.plasticmodelbouw.nl/contact<br /><br /><br />The internal hole was 0.3mm which was just right. A pack of several<br />tubes was less than £10 with postage and took only 3 days BD.<br />Best wishes Brian Darnton.

They are not true shells however but are more closely related to the antediluvian Amoeba of our school text books. In order to protect themselves from the multitude of hungry creatures in the sea, they have simply developed a spiral shell like structure called a test, though the smaller ones prefer the simplicity of an urn shape. In the open ocean, the more globular species float with the plankton and it is these free spirits that form deep deposits on the sea bed. Given a few million years of pressure they will become chalk, as at Ballard Down. They are mainly constructed from some form of crystalline chalk and others look externally almost like porcelain.<br /> In the great lagoons of Poole Harbour they enjoy the muddy less-salty water by means of an adaptation. With a shortage of the minerals of the open sea, they create a bag of chitin-like material and bond silt and sand particles onto this to make their tests. This can be seen in the illustrations on the top row, these are called arenaceous tests and are often very beautiful indeed. <br /> Each species has a preferred level of saltiness and temperature, so seen together they are useful environmental indicators. At Swanage and Weymouth the mortalities are washed up at the most westerly edge of the bays with the sea-coal fragments. This alternate black and white banding is a good clue to their location. In the harbours and lagoons like The Fleet they are to be found around the edges near the high tide marks. as well as embedded in the mud itself.<br />The Foraminifera of warmer waters can be larger than one millimetre but most of the Dorset ones are from a tenth to a half of a millimetre in diameter and provided they are well illuminated they can be seen with a good hand lens or a simple microscope. <br /> This phylum of single celled members of the Protista are just a tip of the iceberg sample of what exists in the seas around our world, when examined with a microscope B.D.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6142755590749587922.post-59670401344407145972009-11-05T01:45:00.000-08:002009-11-05T01:48:38.506-08:00Page4<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFasrmmb9ENu_ZmtQE4VzQoLFr6ICS0VkiIoXyxLeCkGFsO0dXqJl46hzaGztzt2RbM3lgR7v0xVOt0VzRfv1TCC1YAJjTa9HZojWwOY57z3W6P-gvg9C0h3wZkqZ_WiHULfotK_gnICo/s1600-h/Cibicides+lobatulus.jpeg"><img id="BLOGGER_PHOTO_ID_5400554132519514562" style="DISPLAY: block;

It was more intended to be a little Christmas fun for <span class="blsp-spelling-error" id="SPELLING_ERROR_1">microscopists</span> at a time when I was looking at fractals..<br />The work was published on <span class="blsp-spelling-error" id="SPELLING_ERROR_2">MICSCAPE</span> UK and is still in their data base under my name (B.<span class="blsp-spelling-error" id="SPELLING_ERROR_3">Darnton</span>). Several <span class="blsp-spelling-corrected" id="SPELLING_ERROR_4">people</span> had fun <span class="blsp-spelling-corrected" id="SPELLING_ERROR_5">writing</span> in both BBC <span class="blsp-spelling-corrected" id="SPELLING_ERROR_6">BASIC</span> and Q<span class="blsp-spelling-corrected" id="SPELLING_ERROR_7">BASIC</span> using the <span class="blsp-spelling-corrected" id="SPELLING_ERROR_8">relevent</span> language. Recently a friend drew my attention to the fact that a new BBC BASIC is <span class="blsp-spelling-corrected" id="SPELLING_ERROR_9">available</span> at <a href="http://www.rtrussell.co.uk/">http://www.rtrussell.co.uk/</a> . This will run within MS WINDOWS. A free download of a trial version can be accessed as well as the full programme which of course needs a fee. There is much advice on how to use it under HELP but one of the improved features is the automatic colour coding of words so that for example line numbers appear in one colour and words of command in orange etc. The result is that mistakes like incorrect case use, or bad spelling, stand out in the wrong colour which is very useful when writing the programmes.<br />I hope to be able to upload both the images produced, as well as images of the programmes. These <span class="blsp-spelling-corrected" id="SPELLING_ERROR_10">will</span> not copy in text form :I left them as an image in order to demonstrate the colour code effect. These programmes will run on the free download from R.T.Russell and unless developed do not require the ull programme. </div><div align="justify">NOTE If you would like to watch the development of the running programmes then insert a line</div><div align="justify">WAIT 10 anywere in the loop before the NEXT line.</div><br /><br /><br /><div align="justify"></div></div>Unknownnoreply@blogger.com2tag:blogger.com,1999:blog-6142755590749587922.post-21499889000006038692008-11-15T11:51:00.000-08:002008-11-15T12:24:15.449-08:00A New Microscope<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinXzbOGToV1KzprMrRxZJfgeOCm4ipo9tnDc4ugSyJG2We-fykfMu3M9XnCRzuIuTJ0ipAo3wS9AnvDElKFfTDGKFjHZDLouK6ulqk5DlkNd7xkSF_yWiJbtVofygm4vizxaiXwfSGM_o/s1600-h/Crouch.jpeg"><img id="BLOGGER_PHOTO_ID_5268976896247138994" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 242px; CURSOR: hand; HEIGHT: 400px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinXzbOGToV1KzprMrRxZJfgeOCm4ipo9tnDc4ugSyJG2We-fykfMu3M9XnCRzuIuTJ0ipAo3wS9AnvDElKFfTDGKFjHZDLouK6ulqk5DlkNd7xkSF_yWiJbtVofygm4vizxaiXwfSGM_o/s400/Crouch.jpeg" border="0" /></a> My new microscope, which is a Henry Crouch, was recently purchased at the excellent camera shop of Mr Palmer of Bridport Dorset ( Near the bus station). I have improved the fine focus with a new adjustment and I have purchased an alternative low power objective lens of Voigtlaender & sohn A G 38mm (Euryscop), for my little Foraminiferids. The Boxed microscope also contained the standard pair of objective lenses in brass cylinders with data. The Number of the microscope is 8801 and I wonder if anyone has a book containing data such as the age of this instrument. I really would be obliged for this information. <a href="mailto:brian.darnton@googlemail.com">brian.darnton@googlemail.com</a><br /><div></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-6142755590749587922.post-20633163336737200972008-06-17T10:48:00.000-07:002008-06-17T11:06:51.556-07:00Slide of Poole Foraminifera with labelled grid of 12<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsDWnnUHqkhJUn5IDGCRUJdE1k73vL6k2GfIbSEWi96bK2PDcGrEvOQfnw6ft9mUC19ReDozTAp19EoGflB6Wov3MJPTQtBccRAy9wIT9tMkosc37v4J_4dPfI1kMbxJw1udvbVVSRtas/s1600-h/poole+types.jpeg"><img id="BLOGGER_PHOTO_ID_5212909511957534306" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsDWnnUHqkhJUn5IDGCRUJdE1k73vL6k2GfIbSEWi96bK2PDcGrEvOQfnw6ft9mUC19ReDozTAp19EoGflB6Wov3MJPTQtBccRAy9wIT9tMkosc37v4J_4dPfI1kMbxJw1udvbVVSRtas/s320/poole+types.jpeg" border="0" /></a> The slide was created on a standard 3 inch by 1 inch glass slide.<br />The artwork was first completed on a computer and the printout was reduced by photography with a 35mm camera using litho-film.

On the diagram this would be right to left, so the place to search is point B. This is valid for <span class="blsp-spelling-error" id="SPELLING_ERROR_0">Swanage</span>, <span class="blsp-spelling-error" id="SPELLING_ERROR_1">Weymouth</span> and Tor Bay. If the bays of the North East are examined then the flow is from the North Eastern corner of Scotland and on the diagram would be left to right and the site would be at A. This is valid for Scarborough and <span class="blsp-spelling-error" id="SPELLING_ERROR_2">Filey</span>. A quick look at the tide tables of ports either side of the bay in question, will soon determine direction if there is doubt. Of course few bays follow the exact symmetry of a diagram so a little common <span class="blsp-spelling-corrected" id="SPELLING_ERROR_3">sense</span> is required. Do not forget that blog images can be enlarged by a click of the mouse. In estuarine conditions like Poole Harbour,limited deposition zones can be identified by the concentration of shelly remains in the mud. Please see earlier posts.
