Immersion Oil and the Microscope

Since the microscopist's major field of interest is the application of microscopes and related equipment, the fields in which the instruments are used are, in a sense, secondary. However, many scientists, having selected a field, find the use of a microscope a necessity but secondary to their major field of interest. Therefore, the microscope is thrust upon them as an essential tool. Often, basic background necessary for proper use of the "tool" is lacking or inadequate, having been picked up on the job so they can "get by."
