An estimate of the results of treatment of central nervous system syphilis is an extremely complex problem, involving prolonged observation of treated patients, and the correlation of intricate clinical data with equally complicated laboratory investigations. Adequate studies free from controversial bias, comparable to the detailed information now available from many sources as to treatment results in early syphilis, have been lacking until the authoritative discussions of Fordyce1 and of Stokes and Shaffer2 appeared.

In this paper I will outline briefly the methods of treatment in use in the syphilis division of the Medical
