Thirty Diatom Species – Mounted Microscope Slide and Catalogued by Bernard Hartley

Bernard Hartley was diatom royalty. He was born in 1917 and lived most of his life at Yoevil in Somerset. He was a civil engineer and began to make prepared microscope mounts of diatoms in 1957. He worked with fellow diatom expert R I Firth and together they identified and systemised the cataloguing of British diatom species. His other close colleague was the undisputed King of diatoms Klaus Kemp who must have had the steadiest hand known to man.

If you know little about diatoms how about this for a start. These tiny marine organisms [phytoplankton] contribute around 50 % of the marine oxygen production. In the right conditions they reproduce rapidly dividing every twenty four hours – but they only live six days. There are 12,000 known species and an estimated possibility of 200,000. The Amazon basin is fertilised by diatoms remains whipped up into the wind currents from the Sahara – an estimated 27 million tonnes per annum. They take two forms one radially symmetric and the other bilaterally symmetric. Lots more look them up – oh and they are very small and it takes great talent to handle them.

Here we have a slide by Hartley with a carefully placed row of thirty varying diatom types and, almost impossible to find, his original list of species types.

50% of the marine generated oxygen – better save them then! Special scientific collectable – with the list!

South Australia – Marine Bryozoan – Antique Microscope Slide – Ernest Hinton – 150 Years Old

Ernest Hinton worked as a professional microscope slide preparer from 1864 to the end of the 19th Century. His mounts are identifiable by his standard slide labels and small distinctive and very neat handwriting. See example in authority Bracegirdle Plate 21 and page 52. This slide we believe circa 1875.

Hinton became a member of The Quekett Microscopical Club in 1872 [as an aside if you want to know more about the Q.M.C. contact Voyager Bill]. He spent his first 20 years working for Edmund Wheeler, some think he produced all of Wheeler’s slides from 1870. He worked in his own name from Holloway, London. His slides are considered to be of the highest quality.

Here we have an interesting Australian subject a marine lacy bryozoan from the waters off South Australia where they particularly occur. They are actually colonies of small marine animals [or zoids] fused together. Millions can form a colony, and South Australia has over 500 species.

Fine Australian specimen from top London maker circa 150 years old
