Dr. K.R.D. Shaw, of 144, Harley Street, London, W.1, who has had a very wide experience of "prevention" in different parts of the world during the last twenty-five years, has named the following as suitable disinfecting lotions:-- Half a teaspoonful of Lysol in 5 pints of warm water; _or_ One teaspoonful of Sanitas " " _or_ One quarter teaspoonful of Bacterol " _or_ 2 grains of Sulphate of Copper " " N.B.--Where there is grave danger of venereal infection, it is an excellent additional precaution to douche first with soap and water, and douche again with antiseptic lotion. The sooner this is done the better. If all or most of these hygienic measures are widely made known to women, it can rightly be claimed that women have been released from the twin terrors of unwanted pregnancy and venereal infection, which are at the present time ruining their marital health and happiness in so many cases. Even if _some_ only of these measures are adopted, the nation as a whole cannot fail to benefit mentally, morally and physically. The success of the measures, of course, depends to some extent on their being taken _in time_, but in this, as in many other directions, the old proverb holds good: _Better late than never._ II.--PRACTICAL METHODS OF PREVENTION.--(_Contd._) B. FOR MEN: Marriage cannot be made safe, of course, so long as men are permitted to contract venereal diseases, and spread them. Early marriage will greatly lessen the chances of this; tolerated houses under _effective_ medical supervision (such as we had in Paris during the War)[I] would enormously lessen the chances of infection, even where marriage was delayed or interrupted; prophylactic depots where disinfection was properly applied, _and efficiently taught on request_, would be invaluable; but it is at present from self-disinfection, properly understood and efficiently applied, that the community can hope for the greatest and most immediate gain in sexual cleanliness.[J] The following were the directions I gave the Anzacs during the war, distributing these with prophylactics for men and for women (the directions for women being printed in French and English); this action was endorsed by all the leading British, American and French military and medical authorities, from the Commanders-in-Chief downwards, and the effort undoubtedly saved many thousands of men from damage and ruin:-- "AVOID INFECTION. "If you become infected with V.D., the fault is really your own. Either do not risk infection at all, or, risking infection, take proper precautions. These are quite simple. If you take the following precautions _without delay_ you are very very unlikely to contract disease:-- 1. Use vaseline or some other grease (such as calomel ointment) _beforehand_, to prevent direct contact with the source of infection.*
