Engraved plate depicts the components of James Wilson's (fl. 1702-1710) single pocket-microscope, which is explained in detail in chapter III. Wilson introduced this screw-barrel microscope to the Royal Society in 1702. The sliders were held between springs and could be rotated to bring the object into focus. It reached the height of popularity by 1740 and was supplanted by a microscope with an open stage capable of examining live organisms.
This plate comes from The Microscope Made Easy by Henry Baker (1698-1774), a book that popularized the microscope in the 18th century. The first section describes simple and compound microscopes along with how to prepare specimens and calculate their size. The second section introduces the reader to microscopy and the laboratory manual. Also includes "Animalcules," or microscopic animals, and anatomical discoveries made with the microscope.
