The negro sailor is held in very bad repute by these women, and some keepers will not allow him to enter their houses, believing that infection from a colored man is of the worst kind, and almost incurable. The medical returns for the year 1846 give the following tables relating to the women in the St. Paul Suburb: "In January there were 186 women, of whom 15 were sick; the diseases were Venereal disease 9 Itch 1 Colic 1 Gastric fever 1 Rheumatic fever 1 Catarrh of lungs 1 Calculus 1 -- Total 15 "In May, of 189 women, 21 were sick: Venereal disease 9 Itch 8 Gastric fever 2 Inflammation of lungs 1 Spitting of blood 1 -- Total 21 "In August, of 181 women, 17 were sick: Venereal disease 13 Colic 2 Itch 1 Rheumatism 1 -- Total 17 "In December, of 161 women, 18 were sick: Venereal disease 6 Itch 6 Sprain 1 Colic 1 Gastric fever 2 Disorder of digestive organs 1 Cold on the chest 1 -- Total 18 This would give an average of about ten per cent. of the women of the suburb sick." From the facts we have quoted, it is evident that the virulence of syphilitic affections among the registered women is unquestionably mitigated. "_Tertiary syphilis is rare_;" secondary syphilis but occasional, while primary forms have lost their malignity. "There is a marked aggravation of the disease during the summer months, when a considerable influx of strangers takes place. This was particularly observable after the great fire in 1842." _The mildness of the disease, and its easy control, can be ascribed to nothing but the weekly medical supervision. The women are visited at their own houses, and any reluctance or refusal renders them liable to punishment._ Contrasted with this state of affairs, we have the severity of syphilis among unregistered women, who conceal their disease as long as they can. Of those arrested, many are found to be diseased in an aggravated form. In the year 1845, of 138 unregistered women sent to prison, 43 had syphilis, or nearly one third of the whole. Parent-Duchatelet says this proportion is exceeded by the same class in Paris, where the infected amount to one half the illicit prostitutes.
