Table C 85 shows to what a high degree +the heart and vessels especially are harmed by syphilis+. At this point it is to be noted that it may now be considered as proved that the statement that general paralysis causes death in 2.9% cases among the non-syphilitic is erroneous, because general paralysis only occurs among persons who have been affected with syphilis. There is no doubt that the poison of syphilis is also most injurious to the germs and the progeny; the foetus is sometimes infected in the mother's womb, and sometimes suffers by the general debility of the maternal body. A large proportion also of those children who attain a higher age are either enfeebled or damaged in many ways, and this inferiority is often passed down to the grandchildren. The most recent Serum investigations (the Wasserman reaction) are the first to throw full light on this. In Germany syphilis occurs much more frequently in town than in the country; this no doubt dependent on prostitution and on a much greater degree of promiscuity of sexual intercourse in cities. In the country couples keep together with greater constancy, even in the case of cohabitation without marriage. [Sidenote: C 86-88] +The frequency of syphilis and other venereal diseases in town and country+ is illustrated in Table C 86, which gives the result of the enquiries of the Prussian Government on the 30th April, 1900, and Table C 87 after Schwiening, on +the frequency of sexual diseases among military recruits+. Also Table C 88 which gives the +frequency of delirium tremens, epilepsy, and general paralysis+ in the +Prussian lunatic asylums+, points in the same direction by the great differences shown in the frequency of general paralysis in the different institutions. This table, at the same time, indicates what is also supported by other observations, that the +frequency and intensity of harmful influences through alcohol+ are much +greater in towns than in the country+; this may be partly because in cities there is a greater and more regular abuse of alcoholic beverages than in the country, partly because town-life induces a greater susceptibility to alcoholic poisoning than country life (less intense metabolism with sedentary occupations).
