The following is quoted as sample of directions authorised in U.S.A.:--

"The use of this package is not to be construed as a licence to exposure.
Pro-Ven, the original preventive. _The only sure_ way to prevent
infection: _Do not expose yourself._ All exposures should be considered as
infections, for 90 per cent. of all "easy women" are infected. By proper
use of the contents of this package disease may be prevented, as the
action upon the germs is as effective as can be secured by the latest
scientific knowledge; if exposed, _use within two hours_. After contact:
1st. Urinate. 2nd. Remove the cap from tube; take organ in the hand,
holding the canal open; insert tip of the tube and squeeze half of the
contents into the canal. 3rd. Squeeze the remainder on the outside of the
organ, rubbing well into the creases and folds under and back of head and
clear to the body. 4th. Leave ointment on three or four hours. Remember:
It is best to use _Pro-Ven_ immediately after exposure; never delay more
than two hours if possible. _Pro-Ven_ is not a cure--it is designed to
keep men from getting disease; it can be used as a lubricant and
preventive both before and after exposure. _Pro-Ven_ is harmless and will
not cause pain or injury to the sexual organs. Insist upon having
_Pro-Ven_. At all good druggists, or directly by mail, 25 cents a tube; 5
tubes, $1.00. Booklet mailed free upon request. The Pro-Ven Laboratories,
Washington, D.C. This product has been tested and approved by the
Pennsylvania State Department of Health Laboratories."

In addition to _Pro-Ven_, the following proprietary tubes of
self-disinfecting ointment have, to my knowledge, been authorised by the
Department of Health, and samples were sent to me:--

_Procaline_, manufactured by the Hawthorne Drug Speciality Co.,
Inc., 88-90, Reade Street, New York City.

_Cargenios_, manufactured by H.K. Mulford Company, Philadelphia.

_Andron_, manufactured by Andron Hygienic Co., 120, W. 32nd St.,
New York City.

_Sanitube_, manufactured by the Sanitube Co., Newport, R.I., U.S.A.

Excellent printed directions and pamphlets accompany these tubes.--E.A.R.]

It has been found that the 30 per cent. to 33 per cent. calomel ointments
(and suppositories) are not suitable in all cases; and careful
investigations are being made to ascertain the best germicide to use.
Whatever is used must be non-irritating, odourless, stainless, and yet
strongly
