The first three chapters, twenty pages, include a section in which the special equipment required is described and, in some cases, pictured.

The next eighteen chapters, one hundred three pages, describe the selected procedures for a number of tests, most of which are performed upon 10- to 30-microliter specimens of serum and utilize micromodifications of rather well-known methods.
