To the Editor:—In reply to the recent communication of Dr. Schauffler, I wish to thank the doctor for his interest and his kindly criticism. In regard to the ointment, I have used hydrous wool fat, mixed with petrolatum and 1 per cent mercurochrome-220, ever since we first began our work on vulvovaginitis in 1921. Hydrous wool fat, according to Cushney (edition 4, p. 50), "is miscible in twice its weight of water without losing its ointment consistency," and therefore is capable of absorbing the vaginal moisture completely.
I have not materially changed our technic of treatment in the past seven years except for the additional use of the vaginoscope in the study of our patients. Will you kindly refer Dr. Schauffler to our former publications (A Clinical Investigation of Vulvovaginitis, Surg. Gynec. Obst. 36:43 [Jan.] 1923; A Bacteriologic Study of Vulvovaginitis in Children, J. Infect. Dis., 32:444
