120 ERYTHEMA IKTEETRIGO. 



abundant sweating, and the animals being allowed to re- 

 main dirty. The skin is thus apt to be chafed by the har- 

 ness, &c. On horses going long sea voyages, when the 

 urine is apt to flow over the skin, especially in mares that 

 cannot conveniently stale without wetting their thighs, con- 

 siderable excoriations occur. The same happens in animals 

 that are slung. In the latter instance, however, the inflam- 

 mation is often severe from excessive pressure, and such a 

 case properly belongs to the next form of erythema. 



In calves, erythema intertrigo is seen in cases of pervious 

 urachus, when the urine is apt to induce inflammation 

 of the skin over the abdomen. Very fat cattle are apt to 

 become chafed between their thighs, in the arm-pits, &c., 

 when travelled on a hot day and along dirty roads. 



In sheep this form of superficial inflammation is com- 

 mon after shearing, especially in warm climates. In Germany, 

 the sheep suffer much in the filthy stables where they are 

 congregated in large numbers. 



In the summer of 1846, Mr Eobert Read, of Crediton, re- 

 ported that the number of shearling sheep that had died 

 from traumatic erythema amounted in his district to three 

 out of every ten, or even more. Farmers attributed the loss 

 to the hot and scorching weather during the month of June, 

 in conjunction with the attacks of flies. The symptoms of 

 the disease were heat, redness and tenderness of the skin ; 

 the areolar tissue beneath soon became infiltrated with serum, 

 and, in some cases, the skin assumed a yellow colour, with 

 petechial spots. The swellings which occurred were at first 

 hard, and then indented on pressure, and death followed as 

 the result of gangrene. 



Erythema intertrigo is a disease of common occurrence 

 amongst greyhounds. The scrotum and inside of the thighs 

 are often found red and sore from friction.
