The police regulations require that no registered woman shall be under twenty years of age; but in this they have a discretionary power, so as to keep under inspection and supervision some younger girls whom neither the work-house nor prison can reclaim, the experience of the Hamburg authorities having convinced them that such _punitive institutions are seldom successful in the work of reformation_; a truth which will, ere long, be more generally acknowledged, especially in reference to abandoned women, than it is at the present day. The official list for 1844 shows that of the registered prostitutes there were Under 20 years of age 16 From 20 " to 30 years 401 " 30 " " 40 " 74 " 40 " " 50 " 11 --- Total 502 In 1846, of women living in registered houses, there were From 20 years to 30 years of age 199 " 30 " " 40 " " 50 " 40 " " 50 " " 8 --- Total 257 The birth-places of the 502 women reported in 1844 included most of the countries in Germany. There were from Hamburg 108 Hanover 101 Prussia 81 Holstein 78 Other parts of Germany 129 Holland 2 Russia 2 France 1 --- Total 502 The nativity returns for 512 women, in 1846, do not vary materially from the above, the difference in the foreign-born being that there were four, instead of five, born out of Germany. These tables show that about one in five are natives of Hamburg city and territory. Dr. Lippert notices this fact as a small proportion, and accounts for it by enumerating the difficulties of local relationship, parentage, etc., which would be opposed to the registration of native women. These circumstances favor the presumption that many of the unregistered women are city born.
