Hooke used a compound microscope for many of his observations. He helped to improve the design but it was still difficult to use, requiring great skill and patience.
Hooke referred to it as “My faithful mercury, my microscope”

Représentants les plus primitifs des annélides oligochètes ( vers possédant des soies), Aeolosoma possède un corps muni de soies latérales et coloré par des cellules glandulaires épidermiques qui consistent en une vacuole remplie d'un liquide dont la couleur varie selon l'espèce : rouge, vert, bleu-vert, jaune ou parfois incolore. Dans le monde, il existe une trentaine d'espèces réparties dans trois genres (Aelosoma, Histricosoma, Rheomorpha).
it's so art nouveau. I can't believe the concentration and variety of microorganisms. look at all the different types.
Robert Hooke: Micrographia: or some physiological descriptions of minute bodies made by magnifying glasses
London: 1665
Sp Coll Hunterian M.3.1
The Micrographia is the most famous work written by Robert Hooke (1635–1703), a brilliant scientist who made outstanding contributions to a number of scientific fields. Hooke was the curator of experiments at the then newly founded Royal Society, and the results of his observations in using a compound microscope and telescope are recorded in this groundbreaking text. The work begins with an investigation of inorganic matter and goes on to examine vegetable and animal bodies; included are descriptions of minute features such as 'the edge of a razor', various silks, 'the fiery sparks struck from a flint or steel', snow, urine, the leaves of herbs, flies and fleas. As well as being the foundation for the study of microscopy, in this work Hooke proved to be ahead of his time in a variety of areas. Most famously, he used the word 'cell' for the first time in describing the structure of cork; he also explained the diffraction of light independently of Grimaldi's discoveries, and was the first to describe, for example, a bee's sting, the compound eye of a fly, and the structure of feathers.
The book is renowned for its magnificent plates, mostly drawn with the greatest attention to detail by Hooke himself. It was an immediate bestseller.

An interesting look at everyday things.
I bought a cheap USB powered Microscope and then started exploring. Some of the images were very unexpected so I thought I would post a few.

Straight out of Jos Weyers' big bag of Lockpicking and Key Impressioning tricks. These are the kind of tools he uses to break world records with.
This picture was taken at the request of Deviant Ollam and might make it into his upcoming book on Lockpicking techniques.
