A great number of research workers in this country and abroad are devoting their time to finding new and better antisyphilitic drugs. Recently, Sazerac and Levaditi1 demonstrated spirocheticidal activity of bismuth in experimental and clinical syphilis. Fournier and Guenot2 followed the initial reports of Sazerac and Levaditi with extensive clinical observations on 200 syphilitic patients. Since these reports the literature abounds with reports of favorable clinical action of bismuth in the treatment of syphilis.
In this country, McCafferty,3 Pardo-Castello4 (Cuba), Hopkins,5 and Klauder6 have presented clinical and experimental findings.
