This book is an attempt to record what the author has seen and what others have done. His association with Dr. Apostoli has given the impetus which was necessary to inaugurate such a work. In speaking of his master, Apostoli, the author says: "His name will ever be indissolubly linked with gynecological electro-therapeutics. Many of the ablest men of to-day carry with them the delightful souvenirs of individual contact with one who was always courteous, obliging and honest; who is as free from the dross of life as a man can be, and whose extensive observation, patient investigation and research are sources of wonder. I have had the free use of his clinic, of his records, of his library and instruments, since October, 1888, and during the days of treatment in the Rue de Jour I have been in contact with medical men from all parts of the world.
