74 THE PRACTICE OF VETERINARY MEDICINE. 



nostrils become swollen, there is considerable danger of 

 death from suffocation. Another characteristic feature of 

 the disease is that the swelling will disappear from one 

 place and re-appear in another. The udder, sheath, or any 

 part of the body may slough. When the breathing is inter- 

 fered with, there is a snuffling sound to be heard, a slight dis- 

 charge of matter and blood may come from the nose, and, 

 in conjunction with sloughing of the soft tissues, renders 

 the animal a pitiable and loathsome object. There is a loss 

 of appetite, or perhaps inability to take food ; the bowels 

 may be constipated, and the urine is of a higher colour 

 than usual, but scanty. Sometimes the external manifesta- 

 tions of purpura hsemorrhagica are entirely absent — such a 

 case, though, is rare. In a horse with a white heel, or leg, 

 the purple spots in the skin are plainly visible; flies will soon 

 attack and fly-blow the sloughs if not closel}^ attended to. 



Prognosis. — This should be somewhat guarded, as fre- 

 quently the animal, after getting along satisfactorily for 

 several days, suddenly becomes worse, and dies. The signs 

 of amendment are gradual improvement of the appetite, 

 the circulation becomes regular and increases in volume, 

 the swelling of the extremities gradually subsides, the 

 patient recovering in from ten days to six weeks. The 

 last-mentioned time being generally occupied. 



Treatment. — Eemove the patient from all obnoxious sur- 

 roundings. He should be placed in a scrupulously clean 

 and dry loose box, to which fresh air and sunlight have 

 free access. In purpura the products going to form 

 albumen and fibrin are deficient in quantity, hence potassae 

 chlor. is indicated on account of its peculiar action on the 

 blood, the dose being gi. — giss. daily for the first day or 

 two, then 5ii. — 5iii. daily. 01. terebinth as a styptic, in 

 doses of 3ii. every alternate day or so, is very beneficial ; it 

 also tends to regulate the bowels. Enemas are beneficial,
