    In Psoriasis vulgaris tlie patches are generally of large size; in P. guttata, the place of the patches is occupied by small spots. In each case, the patches or spots may be on any part of the body, or upon almost every part of the body at the same time. P. inveterata is the name given to the most obstinate and inveterate form of the disease. One variety has been called P. gyrata, but this ought more properly to be passed over to lepra; for regu- larity of form, as we shall soon see, is the chief artificial distinction between lepra and psoriasis. Other names, as P. palpebram, P. labialis, P. prceputii, P. pudendalis, P. scrotalis, P. palmaris, &c., indicate simply the locality affected. The latter variety is a common con- dition in grocers, bakers, dyers, masons, washer- women, &c. Cases of chronic eczema and lichen agrius are not unfrequently met with, in which it is by no means easy to draw the line of dis- tinction between them and psoriasis; and this difficulty is increased by the fact, that in certain cases psoriasis may become blended with an unusual amountof erythematous conges- tion, and losing the want of moisture and dis-
