practical slide staining
by Mike Asquith. This will be an excellent chance to experiment and get ‘up-close and dirty’ with different types of stain. It will certainly be an interesting, and perhaps a very colourful evening.

staining, an introduction
by Mike Asquith. One way of highlighting the different structures of a sample is by means of staining. Mike gives an introduction to some of the theory of staining with demonstrations.

diatoms (part ii)
by Mike Gibson. In this session we show you how to prepare and make permanent slides of these beautiful plant life forms. Also how to adjust your microscope for the best lighting and contrast.

diatoms (part i) – an introduction
by Mike Gibson. If you’ve never seen these beautiful plant life forms now’s the chance to find out more. A unique feature of diatoms is that they are enclosed within a cell wall made of silica and called a frustule, which show a wide diversity in form, but are usually almost bilaterally symmetrical - hence the group name. Learn how to view clearly these often difficult subjects under the microscope.

victorian slides (part ii)
by Tim Newton and Mike Gibson. Another chance to view slides from our own collection and others: Tim will be setting up a couple of microscopes using illumination methods favoured by our Victorian forebears, including the use of a ‘bull's-eye’ lens, to enable us to see the slides as they would have seen them. Then he will show you how to reproduce these effects on more modern microscopes - demonstrating such techniques as dark ground, critical oblique and condenser-less illumination.

entomological workshop (part i) - fleas
by Tim Newton. There are over 60 different species of flea found in the UK, and in this first session Tim will show you various species, and outline the differences between mammal and avian fleas.
