Ciliate feeding: see bottom of page for details.

Micrographia is for those who use microscopes in their investigations of the world around them.
It is for students and teachers of (especially) fresh water biology in their search for creature identification and illustrative material, for both amateur and professional light microscopists seeking to extend the performance of their instruments and to record the images they produce ..... and for anyone at all who feels like a browse through a minutely detailed world of small animals, small plants, and small things.

This website was created by John C Walsh, who died on 18th November 2012. It is maintained by his friends in order that John's thoughts and micrographs may continue to be seen by anyone who shares his fascination with the world of very small things. Requests for use of John's images will be dealt with by his Estate, which may be contacted via the email links in this site.

Feature Picture.

Dirt on an eyepiece lens.
A galaxy of oil-exuding airborne particles which have settled on an exposed microscope eyepiece -- and an unexpectedly interesting exercise in image interpretation for the microscopist.
Editorial and Comment. Micrographia site news, recent and current events in science and microbiology, plus anything else deemed relevant.
Articles. A considered selection of articles, culled from various sources, most likely to be of interest to users of the microscope in particular, and to those curious about Life on Earth in general.
Specimen Gallery Directory.

Elodea plastids   Water mite
The Specimen Galleries are a major part of the site.
The directory groups biological specimens according to physical features and habitat, and non-biological specimens by subject.
Intended for those needing to identify creatures and objects seen under the microscope, as well as for the casual browser.

Logo Animation:   Particles of debris caught in the feeding current generated by this sessile ciliate (possibly Rhabdostyla spp) have been loosely compacted into a ball which will rotate as long as the organism continues to feed.
The original sequence was shot on Kodachrome 16mm film using synchronized electronic flash, which has rendered the action of the cilia sharply in each frame. (x 200).
