Ichthyosis. Ichthyosis (fish-skin) is included by Will an in squamae. It is occasionally seen as a congenital or transmitted I fforni of disease; the skin is so much thickened that iit assumes a horny texture, with a tendency to fall oft’ in llarge scaly patches; these are, in appearance, quite dis- ttinct from the scales of either psoriasis or lepra. In the sspecimens which have fallen under my notice, the epi- (dermis appeared to be hypertrophied; the scales were m completely condensed and blended together, and it ’■was almost impossible, without soaking for some time in sa solution of potash, to separate and render them thin eenough for examination under high-powers of the micro- sscope. This difficulty appeared to be increased in one oor two instances by fungus threads binding the scales :more intimately together, weaving them, as it were, into a consolidated mass. Vitiligo (veal-skin) is a disease occurring in patches over the surface of the body; the scales fall oft’ and leave a white state of the skin, not unlike veal in appear- ance.
