West Midlands spring meeting

Saturday 14th April 2018

Mike Woof organised another well-attended joint meeting of the Quekett and the Postal Microscopical Society, held again in 2 rooms at the Haling Dene Centre in Penkridge, Staffordshire. The morning was given over to exhibits and sales (items ranging from brochures and bulbs to a large trinocular microscope outfit), and the afternoon was given over to lectures.

Geoff also showed a few home-made LED illuminators.

Jeremy Poole brought the Zeiss Photomicroscope II that he bought a few years ago and to which he has recently strain-free objectives and added accessories for polarised light (rotating polariser and stage, calibrated rotating analyser, Bertrand lens and strain-free eyepiece with cross hairs). Jeremy showed some of his own slides, a Brian Darnton arrangement of leaf scales and fern scales, and several slides belonging to Robert Ratford. Jeremy also brought a much smaller polarising microscope.

Jeremy also brought some books, A colour atlas of rocks and minerals in thin section by W. S. MacKenzie & A. E. Adams, The preparation and mounting of thin sections and small whole mounts of rocks and minerals for microscopical examination by Derek D. Underhill, An introduction to crystal optics by P. Gay and Minerals and the microscope by H. G. Smith (revised by M. K. Wells).

Joan Bingley attended the M. C. Cooke Lecture “Why flies” by Dr Erica McAlister on Tuesday 10th April and brought a selection of Diptera slides (including some by Ron Cushing) that we could examine using a simple compound microscope. Erica’s lecture is available in the password-protected area of the Quekett website, and her first book (The secret life of flies) has recently been published.

John Fletcher brought an elaborate black and chrome monocular microscope with a ½″ NA 0.5 objective constructed as 3 cemented doublets. This construction was common in the 19th century until superceded by the Amici design with a single front element. Computer programs for designing and optimising lens designs now enable us to explore the possibilities of the 3-doublet design.

John Ward brought a brass Wenham binocular microscope fitted with a tourmaline analyser, an uncommon and expensive alternative to a Nicol prism. Compared to a Nicol prism (which John also brought), the tourmaline analyser provided better extinction and an unobstructed field of view. The microscope was fitted with a Smith, Beck & Beck 1½″ objective.

Les Franchi brought a very unusual Watson item, a Waterhouse pattern Museum Microscope with a rotating drum that can hold 12 slides. Museum visitors could change slides by turning a knob on the side and focus by turning a ring around the eyepiece, but the other controls were inside the locked case. Les had rescued the microscope when it was being thrown out by Birmingham Medical School, and fitted his own slides, objective and eyepiece. It was originally supplied with a low-power 1½″ or 2″ objective. Tony Dutton had identified the instrument and provided a page from the 1938 Watson catalogue. Illumination was provided by a hemispherical LED lamp.

Les also brought a few other items, including a camera lucida and a simple microscope.

Mike Gibson showed his Lomo Biolam С1Ч42 fitted with a Meopta monocular head (no adapter needed). Mike had replaced the bulb in the lamp housing with a hemispherical LED light, now available for just £3 and fitted with an on/off switch. Power came from a power bank available from pound shops. He was also promoting the Annual Exhibition of the Microscopy Section of the Northamptonshire Natural History Society on Sunday 24th June, where Mark Powell will demonstrate how to make slides of lichen.

Mike Samworth brought a Nikon stereomicroscope so that we could examine 2 slides made by Doug Morgan, the oldest PMS member who had recently passed away aged 98. These 2 slides, of shield-bug egg cases and iron pyrite crystals, were labelled as having been made in February 2000 and having received the Eric Marson Award from the Quekett.

Robert Ratford brought a Vickers M15 binocular microscope, a Russian microscope in its fitted metal case and a box of Biosil slides. He also brought a box of dirty and damaged slides that he had intended to restore, but he has now realised that he will never have the time and so he was giving away the slides to anyone who was interested.

Stephen Parker brought his trinocular Nikon S-Ke microscope fitted with the uncommon interference phase contrast attachment and condenser. This system uses normal Nikon achromat objectives and a birefringent phase ring between a polariser, an analyser and a ¼-wave retardation plate in the attachment. Setting the analyser at 45° and rotating the polariser provides a range of colour contrasts. Stephen used a Chinese inspection camera to show images on a Samsung television.

Lectures

After a break for lunch, we set out chairs in the larger room for 3 talks.

Bill Morris lecturingBill Morris giving his talk

Bill Morris spoke on “Making microscopes: Optical construction kits since the 1930’s”. Bill is fascinated by kits for children that can be used to construct microscopes. It is possible to construct microscopes using Meccano or Lego, but Bill concentrated on optical kits. Brands that he has bought (mostly on eBay) and tested include Construments, Optic-Variant, Clubman, Optik Montage, Optikit, Optical Science and Scope Constructor. He is still trying to find a FischerTechnik at a reasonable price. Bill showed us photographs of the kits and the assembled microscopes, and photomicrographs taken with them. Sadly, none of them have good design, good instructions and good lenses. Bill’s favourite is the Construments kit.

John Birds worked for many years at Chatsworth House and has many stories to tell about his time there. His reminiscences today including rounding up the deer during a foot-and-mouth epidemic to prevent them being infected by visitors, stringing fairy lights for the first Christmas opening, his first industrial accident after more than 20 years of safe working, his alarm at a broken window and blood and tissue on him that turned out to be from a pheasant caught in a very strong wind and blown through a window and into a woodworking machine, and many rooms full of items that were once ordinary but were never thrown away and are now valuable

Mike Gibson spoke on “The enigma of Elgar’s microscope”. In 2015, Mike and Ray Sloss visited the Elgar Birthplace Museum and ran a Micro-Science Activity Weekend there. Soon after, they returned and photographed all of the slides in the Museum. Another Quekett member, Eric Impey, had been to the Museum earlier and wrote an article “Sir Edward Elgar and the microscope” for the Journal. While he was living in Hampstead in 1911–1921, Sir Edward developed an interest in microscopy, owned 6 or 7 microscopes and several hundred slides, and collected specimens from Hampstead Heath and Highgate Ponds The only surviving microscope is his Ross No. 1 in the Museum, and they only have about 130 of his slides. Mike showed us photographs and photomicrographs of many of the slides in the Museum. Mike and Ray wrote an article “Elgar and the microscope” for the Summer 2016 issue of the Journal.
