Note J — II.—PRACTICAL METHODS OF PREVENTION.—(Contd.)

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.
