West Midlands autumn meeting

Saturday 18th September 2021

Mike Woof organised another joint meeting of the Quekett and the Postal Microscopical Society, held as usual in 2 rooms at the Haling Dene Centre in Penkridge, Staffordshire. Because of the Covid-19 epidemic, this was the first Penkridge meeting since September 2019, so there was lots of catching up with old friends. The morning was given over to exhibits and sales, with items ranging from filters and slides to trinocular microscopes, and after a break for lunch there were 3 talks in the afternoon.

Joan Bingley has been working on a new citizen science project on birds’ nests, and showed one nest from Cobham and another from Nuneaton that she had started to analyse for their invertebrates (fleas, mites, flat flies, etcetera) and their composition. She showed the nests, some of their contents, her draft of notes for the project, and asked for feedback.  The project was also the subject of Joan’s talk in the afternoon.

The other entry was from Les Franchi, an example of his Pol-Rheinberg technique applied to the hind leg of Melophagus ovinus.

Talks

“Looking at birds’ nests” by Joan Bingley

Joan BingleyJoan Bingley

Joan Bingley is developing a new citizen science project on birds’ nests that will involve collecting and identifying invertebrates (fleas, mites, flat flies, etcetera) and analysing the composition of the nests. She showed us photographs of two quite different nests, a great tit from Cobham and a robin from Nuneaton, and compared the materials of which they were constructed. It is illegal to disturb nesting birds in England, Scotland and Wales, and most parasites leave the nest soon after the young have departed, so it is not clear how to sample them.

“Adventures in anaglyph 3D” by John Ward

John Ward showed us lots of his anaglyphs of diatoms and mosses, as well as Golgi-stained brain cells, the hooks that hold honeybee wings together, and turnings from mild steel. The diatom photomicrographs were mostly taken with a 100× objective and were stacks of 50–100 images. For photomicrographs, John takes photographs through one eyepiece with a pair of semicircular masks (◐ and ◑) to obtain the two images. For macro with a reversed Pentax 50 mm standard lens, John uses a separate iris diaphragm to take image through the left and right sides of the lens. Sharpness is important, so all of John’s images are stacked. John provided us with red and blue 3D anaglyph glasses (blue over right eye) so that we could appreciate his photographs.

“Robert Hooke – the Royal Society’s dogsbody” by Terry Hope

Terry HopeTerry Hope

Terry Hope provided us with all sorts of information about Robert Hooke, who we associate with microscopy but whose interests also included architecture, astronomy, geology, lens making, physics, surveying and telescopes. He was the most loyal curator and experimentalist the Royal Society ever had. He is perhaps best known for his illustrated book, Micrographia: or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses. With Observations and Inquiries Thereupon.
