By this table it appears

that

males

are more often affected with psoriasis

than females, they here forming 53.1 per 100

of the entire number,

and the

females forming 46,9 per 100 ; liais corresponds somewhat to the proportion observed by others, Neumann making the proportion of males 65 per cent.

The youngest patient seen with the disease was a female about two years ofage, the oldest a male, just seventy-five years of âge. ït will be seen that the largest number of cases applied for treatment belween the âges of 25 and 30, when there were 170 cases out of the thousand. Between 20 and 25 years of âge there were 137 cases, and between 30 and 35 years of âge 432 cases.

Relatively few cases were seen during the very early years of life. In but 4 instances the patients were five years or less of âge ; in the next five years there occured 33 cases ; of these 27 were females and 6 males. It will be observed also that relatively few cases are met with in advanced life, but 80 cases in the entire thousand being seen after 50 years of âge. Of the entire thousand the disease was seen in 439 patients between the âges of 20 and 35 years of âge.

It is impossible, however, to draw from this table any exact conclusion with regard to the âge or period of life at which psoriasis is most likely to manifest itself, for. by reference to the next table it will be seen that the éruption commonly first appears at a much earlier âge than will be inferred from the preceding table.
