One of the standard references in the field. The microscope collection documented here is very diverse, having been started by Lieutenant John S. Billings, a medical officer of the US Army, and curator of the Army Medical Museum from 1883 to 1893 and extended through donations and acquisitions in the years since. It is very helpful for dating unknown microscopes by form, useful for collectors, dealers, and historians. This second edition contains an additional 32 pages of microscopes added to the collection since 1967. The many, many photographs, descriptions of each instrument (including dimensions) make this an essential reference for the collector, dealer, or historian.
