[BY] Through the consultation about pregnancy, several cases became known to the author where respectable young men and women, who, known to each other and of the same set in society, would never had thought of indulging in illicit venery, after participating in a carouse together found themselves in some hotel the next morning, without the least knowledge how they landed there. [BZ] The automobile has caused the ruin of more respectable girls than all the poverty of the slums has ever been able to accomplish. [CA] In the present state of society, the most rabid, radical and free-love advocate will scarcely cherish the thought of his young daughter becoming impregnated by a chance acquaintance. Nor will the child, born of such a union, thank his parents for the bestowal of the handicap of illegitimacy upon his life journey. [CB] How little influence fear of infection has upon the conduct of our young men, leading a promiscuous life, shows the following characteristic case. The author was consulted by a young man, engaged to be married, who was suffering from gonorrhoea, complicated by a terrible orchitis. He was put to bed where he suffered terrific pains for quite a number of days. The first question the patient asked, after he got well, was whether he may marry the next month. He was warned against marrying before repeated examinations have shown the absence of gonococci. He then requested some drug for the prevention of another infection. Now, if there ever was a man who had a reason to fear infection, it surely was he. He suffered enough. Still he was ready again to plunge into his promiscuous sex-life, without any thought of the young girl who was waiting to become his bride. [CC] Col. L. M. Maus, U. S. A., has used among the troops of his department of the Lakes for one year, with surprisingly effective results, a small tin collapsible tube containing a paste made of phenol 3 per cent., calomel 25 per cent. and lanolin 72 per cent. He has found this paste an absolute preventive against gonorrhoea, chancroid and syphilis, if properly used within half an hour after contact. One-third of the paste is squeezed into the urethra, the remaining two-thirds are applied to the glans. Cleansing the genitalia is not necessary, if the tube is used. [CD] As long as there is a supply of prostitutes there will always be a demand for the services of these unfortunates. The notion that it is the demand which creates the supply has been spread by superficial observers. It was not the demand for the telephone that led to its invention, or the demand for railroads that led to invention of the steam engine. As long as we allow mental defectives to propagate their kind, there will always be degenerate women who will prostitute themselves, and by this very act create a demand.
