In this brochure the authors discuss the technic and interpretation of the colloidal benzoin reaction in cerebrospinal fluid, a test which they originally described in 1920. The discussion is accompanied by photographs and charts illustrating the colloidal benzoin curves obtained in various pathologic conditions. Of especial interest is the comparative study made by the authors of the colloidal benzoin and the Wassermann reactions. A bibliography is appended, consisting of papers written by the authors and their associates.
