Tri-State medical journal and practitioner . is site that a cup appears andthat a certain amount of itching is experienced. The color of the lesionis a sulphur-yellow at first, but it soon assumes a dirty-yellowish tinge from 306 Original Articles. the foreign material which adheres to it. It is quite adherent to the skinon account of a certain amount of the horny layer of the skin forming alap over its edges. When separated it is found to be quite friable, and is,in great part, composed of the vegetable parasite which causes the distribution of the lesions is discrete at first, but it is not unusual forthe scutula to form one mass, simulating a dirty crust and having a tendencyto become quite thick and friable. The distribution of the disease ispeculiar in one respect. It may be either limited to the scalp or it mayoccur upon the scalp and body. It is rarely limited to the latter except inspecial instances. For example, it may be found in infants at the umbili-cus alone, but this is rather of exceptional Fig. 2. Favus of the Scalp. In favus of the body a small area, such as the knee or elbow, may bethe only portion involved, or it may attack the entire body, as shown inFigure 1. It will be seen in this figure that the lesions, whilst occurringall over the skin, still retain their discrete distribution. Another peculi-arity, and this is one which* renders the case more interesting, is that thelesions are very large—one or two inches in diameter. In spite of this largesize they remained cup-shaped and, as the figure shows, they were verythick. Of course, cases like this one are rather the exception than therule, but serve to demonstrate very forcibly how the parasite will flourishon a soil which is favorable to its growth—heat and moisture—as well as notdisturbing the lesions contributing largely to this exuberance in formationand increase. It will be further observed that there is no ocular evidence r A \ L s-C ..VI5v:_ 3 C 7 o
