This is a small monograph of thirty-four pages, liberally illustrated with curves and four photographic reproductions of reactions. It is simply a report of the technical experiences of the authors covering a large series of observations; the theory and interpretations of the tests are not covered.
The test is based on principles similar to those on which the Lange gold reaction is based, and gives similar results. A much larger series of dilutions is used, generally sixteen, and the resulting curves are therefore more complicated and give promise of being of greater clinical value in the more unusual forms of cerebrospinal syphilis. The tabetic and paretic curves closely resemble the Lange curves.
