David Richman's (USA) studies of the amazing diversity of spiders in certain
habitats prompted this thought provoking essay on biodiversity from his
beginner's microscope? Paul James (UK) looks at the old toy microscope
of a good design which inspired his interest in microscopy, with his thoughts
on the toy microscopes then and now.
mucus belts of the Oscillatoria Wan Yu (China) describes and illustrates
