was probably tricophytic in origin. Sehleiffer, however, claims to have proved 

 that aspergillus fungi were the cause of the trouble. 



Ringworm of calves ( Kalbergrincl, Teigmaul) is a trico- 

 phytic disease of sucking calves in which thick bran-like or 

 dough-like dry scabs develop in the region of the mouth and 

 face, more rarely on the body. The scabs are roundish or oval 

 in form and show hairs with split ends sticking out ; they coalesce 

 and finally unite to form an extensive mass of crusts. The dis- 

 eased spots are sensitive to pressure and violent itching is pres- 

 ent, which interferes with the nutrition of the animal. 



That ringworm of calves belongs to the ordinary herpes, was proved by 

 Hahn by means of microscopical examinations, and by Schindelka in his animal 

 experiments. (The transmission of the crusts of calf ringworm to cattle and horses 

 caused the usual form of herpes in these animals.) 



(c) Herpes in the Sheep. 



Herpes tonsurans crust aceus is rather a rare disease in 

 sheep, which begins with the sudden appearance of circular 

 spots, in size like a one-cent to a twenty-five-cent piece, on the 

 back, chest, shoulders and neck. These spots are recognized by 

 the fact that they mat the wool into tufts and cause it to stand 

 up straight, giving the sheep a tousled appearance. The skin 

 is reddened, often brownish in the center of the spots and cov- 

 ered with grayish white, bran-like rather firmly adherent scales 

 or scabs. The itching is intense, especially at the commence- 

 ment and causes the animal to scratch and rub continuously, 

 and this leads to a rapid extension of the eruption, with coales- 

 cence of the spots and finally extensive baldness (Brauer, Schin- 

 delka). 



In lambs herpes manifests itself similarly to the disease in 

 calves, it is called ringworm of lambs {Ldmyner grind, Milch- 

 grind, milk scab), but is a rare disease. Thick and dark colored 

 crusts form on the face, especially around the eyes and ears, 

 exceptionally also on the neck. Now and then the disease leads 

 to cachexia and even causes death (Schindelka). 



Ringworm of sheep shows a tendency to recurrence 

 (Anacker). 



Eingworm has been observed very rarely in goats, in which it occurred as a 

 very mild skin disease. 



(d) Ringworm in the Pig. 



Two cases of the disease were seen by Siedamgrotzky and 

 one by Schindelka. It occurs most frequently on the back and 

 on the outer surfaces of the thighs; also on the croup and the 

 sides of the chest. There are only isolated reddish and roundish 

 spots as large as a twenty-five-cent to a dollar piece, the raised
