It is difficult to estimate the number of prostitutes--impossible to determine it exactly. The police may approximately determine the number of women for whom prostitution is the sole or chief source of income, but they ~can not~ determine the far greater number of those who resort to prostitution as a partial support. Nevertheless the numbers that have been determined are enormous. According to Oettingen at the close of the sixties of the last century the number of prostitutes in London was estimated to be 80,000. In Paris on January 1, 1906, the number of enrolled prostitutes was 6,196, but more than one-third of these manage to evade police and medical control. In 1892 there were about 60 public brothels in Paris, harboring from 600 to 700 prostitutes; in 1900 there were only 42. Their number is constantly decreasing (In 1852 there were 217 public brothels). At the same time the number of private prostitutes has greatly increased. An investigation, undertaken by the municipal council of Paris in 1889, estimated that the number of women who sell their bodies had reached the enormous figure of 120,000. The chief of police of Paris, Léfrine, estimates the number of enrolled prostitutes at 6,000 and the number of private prostitutes at 70,000. During the years 1871 to 1903 the police inhibited 725,000 harlots and 150,000 were imprisoned. During the year 1906, the number of those who were inhibited amounted to no less than 56,196.[106] The following numbers of prostitutes were enrolled with the Berlin police: In 1886, 3006; in 1890, 4,039; in 1893, 4,663; in 1897, 5,098; in 1899, 4,544, and in 1905, 3,287. In 1890 six physicians were employed, who performed examinations for two hours daily. Since then the number of physicians has been increased to twelve, and since several years a female physician has been employed to perform these examinations, notwithstanding the objections of many male physicians. In Berlin, as in Paris, the enrolled prostitutes only constitute a small fraction of the entire number, that authorities on this subject have estimated to be at least 50,000. In the single year 1890 there were 2,022 waitresses in the cafés of Berlin, who, with very few exceptions were given to prostitution. The yearly increase in the number of harlots inhibited by the police also shows that prostitution in Berlin is growing. The numbers of those inhibited were: In 1881, 10,878; in 1890, 16,605; in 1896, 26,703: in 1897, 22,915. In the year 1907 17,018 harlots were brought to trial before the magistrates, which was about 57 for each day the court was in session.
