Plate III depicts the double reflecting microscope, which is described as having a greater ease of use than John Marshall's (1663-1725) great double microscope. The components and operation are discussed in detail in chapter V. The double reflection illuminates specimens, providing greater clarity. Concave glass is used to retain liquid specimens. Glass tubes are used to immobilize living organisms for examination.
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.
