"Speaking in regard to licensed houses, Captain Walker said that he _had not found one case of venereal disease_ contracted in a licensed house in the City of Paris, and he could only suppose that the people who were responsible for putting the licensed houses in Paris out of bounds knew nothing at all about the real facts of the case.... In the licensed houses in the City of Paris, during the year 1917, _only five cases of venereal disease_ were contracted; and in 1918, up to April 20th (the day he was speaking), _there had not been one case of venereal disease contracted in a licensed house in the City of Paris_. But out of 200 women arrested on the streets of Paris during the month of April, _over twenty-five per cent. were found to be infected with venereal disease_. In the months of November and December, 1917, the French authorities had made a round-up on one boulevard of seventy-one women, of whom _fifty-five were infected with venereal disease_; a few days later the French authorities repeated the same procedure on another boulevard; something like _one hundred women_ were arrested, _and ninety-one per cent. were infected with venereal disease_."--p. 134, _Public Health_ (England), September, 1918. I supervised a tolerated house in Paris for over twelve months (1918-1919), and had no cases of disease either among the women or the men. The women attended from 2 p.m. to midnight and resided in their own homes.--E.A.R.] [Footnote J: Among the first medical men in Great Britain to recognise the importance and effectiveness of self-disinfection was Mr. Frank Kidd, M.A., M.Ch. (Camb.), F.R.C.S. (Eng.), etc., of the London Hospital. A full statement of his evidence before the Royal Commission on Venereal Diseases is given in Mr. Kidd's book, "Common Diseases of the Male Urethra" (published by Longmans, Green and Co., 39, Paternoster Row, London, etc., in 1917). The diagram of male organs of generation I have used on page 36 was taken in outline from Mr. Kidd's frontispiece, and during the war I found all the illustrations he gave most helpful with the soldiers, although the book itself was written for the purpose of enabling doctors in outlying districts to treat patients on modern lines with success. Mr. Kidd designed prophylactic tubes, which have been sold in England on his order for more than fifteen years. He tells me they have been used all over the world by his patients, and that as far as he can ascertain "_they have never failed, when used properly and intelligently_."--E.A.R.]
