Sen presents the Prize Essay of the Indian Medical Gazette for the best paper on this subject. He gives an outline of the contributions toward the present knowledge of syphilis, quoting freely from the published articles of others. He includes his "Notes on Salvarsan" reprinted from the Indian Medical Gazette of August, 1914. Sen gives arsphenamin at intervals of four weeks, as he asserts that the drug given in doses of 6 dg. is not completely excreted even after three weeks.
The monograph gives no indication of the prevalence of syphilis in India. It is of no value to the syphilologist of this country.
