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 antiseptic.  It is possible, I think, that chinosol[P] best fulfils the required conditions.  It was first suggested by Surgeon-Commander Hamilton Boyden, R.N., of the Whale Island Gunnery School, England, who was led to choose it because of its known usefulness in ophthalmic work.  It does not matter to the general public what drug is finally selected; all that matters is that it should be of proven value for the purposes required.  Women can help forward this great work by deciding in their own mind:  (1) That the medical prevention of venereal disease is right and wise; and (2) That the authorisation by the Public Health Departments of efficient means of preventing venereal disease will consequently have their support.

[Footnote P:  Chinosol (C9H6NKSO4), potassium oxyquinol in sulphonate, is a proprietary disinfectant and deodoriser.  After some little experience of it in ointments and suppositories, I believe it deodorises these—­an important advantage.  But further investigation is necessary.—­E.A.R.]

We must all of us first learn to separate the moral from the medical campaign.  Both are necessary, but they must be conducted independently.  America is doing this; England is not.  In England venereal disease is still officially regarded as something to be discussed; in America—­as something to be destroyed.  Thus America is winning and England losing the battle against the venereal microbe.  The Overseas British Dominions will undoubtedly follow the lead of America—­particularly that of Pennsylvania.  Hence, these newer countries may have a glorious future, England—­only a splendid past.[Q]
