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.]

[Footnote K: Since this was written, a large number of experiments have
been made with the single treatment tube, containing an ointment
destructive of all forms of venereal disease microbes, whether used before
or after connection. The Pennsylvania Department of Health is within
measurable distance of finding a solution of this problem--the production
of a cheap, portable, easily applied and thoroughly efficient
self-disinfecting ointment.--E.A.R.]

It was clearly proved that so long as men took these simple precautions
(which I always explained _personally_) they were very unlikely to
contract disease; most cases of disease came from multiple connections
with the women of the cafes, etc. It was difficult to impress on ordinary
men's minds the fact that _each and every connection was a danger_; that
the danger of infection began immediately there was any contact, and that
it continued until disinfection, and was renewed as well with each fresh
connection during the night. If the danger had continued for several hours
in this way, the men were told to go to the medical depot or report to a
doctor as soon as possible. When they did so they were saved from disease
in the vast majority of cases, even up to twenty-four hours after
