DISEASES OF THE SKIN AMONG DOMESTICATED ANIMALS.

few days as quickly as it has risen. There is no solution of the 
continuity of the integument, and it is followed by a small and 
insignificant desquamation. 
Shortly after the outbreak of a more or less violent attack of 
fever, accompanied sometimes by gastric symptoms, a circumscribed 
spot of the epidermis is seen to be hot, tense and very painful to 
the touch. When occurring upon unpigmented skin a vivid red¬ 
ness appears,but little elevated above the level of surrounding parts, 
and spreads rapidly. 
As a rule the redness finally involves the entire extremity and 
is divided from the normal skin by a raised or even swollen bor¬ 
der. But rarely does it begin gradually. 
Severe cases may go on to the formation of vesicles, the fluid 
of which is purulent. These soon burst, and leave small excoria¬ 
tions behind. Inflammation of the lymphatic vessels and glands 
belonging to the affected portion of skin are also occasionally ob¬ 
served. 
This malady is undoubtedly caused by a streptococcus, and 
but rarely ends unfavorably. Treatment consists of lukewarm lave¬ 
ments with soap and water to relieve tension, and the inunction of 
carbolized oil or carbolized glycerine; all the so called specifics 
have proved worthless. Camphor ointment, iodine solution, re¬ 
sorcin and the subcutaneous injection of carbolized water or sub¬ 
limate solution have no effect on the disease. 
9.—Dermatitis gangraenescens. 
(Brand mauke). 
Horses and cattle are occasionally affected by more or less ex¬ 
tensive gangrene of the skin, especially upon portions of the ex¬ 
tremities covered with white hair. Traumatisms of various kinds 
—falls, solar heat, wet, ice, etc., may cause the affection. Scars 
are left after it has run its course. A ery probably the circulation 
is interfered with by the injury—and hence occurs death of an 
area of skin. 
Treatment consists of the removal of necrotic tissue, and the 
use of antiseptics.
