Engraved plate depicts the components of a pocket microscope with a mirror or speculum used to project light through the specimen. The parts and functionality are explained in detail in chapter IV, entitled "A new invention for fixing the pocket-microscope, and giving light to it by a speculum."
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.
