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 afterwards or
a little longer.[L]

[Footnote L: In 1915-1916 Colonel Sir James Barrett, then A.D.M.S. of the
Australian Force in Egypt, had successfully applied prophylaxis, but
unfortunately he was invalided for a time to England in November, 1916,
and with the evacuation of the Dardanelles there was a severe outbreak of
