This differs from leprosy in the eruption being more irregular. The spots sometimes come out in thick clusters, and blend in various ways. The eruption is not circular as in leprosy, but consists of irregular patches of every extent, and the surface is more tender and irritable than in leprosy. There are many varieties of this disease. The "Baker's Itch," "Grocer's Itch," and "Washerwoman's Scall," are only different varieties of psoriasis.
TREATMENT. -- The acetic tincture of blood-root or oxide of zinc ointment, may be applied to the eruption, and the skin should be kept clean, and the pores open. The inflammations may be lessened by emollient and soothing applications. Sea bathing is very good. The general health should be attended to in all cases, and the tonics given in necessary cases.
