Rh differs from psoriasis in one respect. While in the latter affection the infiltration of the skin is slight and the accumulation of scales a prominent feature, in the papular syphilide the infiltration of the skin is considerable and the scaling is comparatively slight.

It is a noteworthy fact that many patients suffering from



psoriasis are unusually well developed and robust in appearance. It is not, like eczema and certain other skin affections, a disease of the weak and the neglected, but one which seems to delight in attacking those who are strong and well nourished. In any case, however, where the tendency to psoriasis exists, the eruption is certain to be most severe whenever the patient is weakened by lack of proper food or by overwork.
