PURPURA HEMORRHAGICA. 



187. A six-year-old entire horse, brought for examination on the 

 5th March, 1897, suffering from a corn in the off fore-foot. The bar 

 and branch of the sole were thinned, the foot reshod, and a tar 

 dressing applied. 



On the loth March the horse was returned here. For two days 

 before all four limbs had been swollen and oedematous. 



State on Examination. — The swellings were of considerable size, and 

 extended as high as the elbows and stifles, where they were sharply 

 delimited. The mucous membrane of the nose was covered with 

 petechias. There was no swelling about the face. Walking was 

 difficult, the limbs being carried stiffly and not being flexed. The 

 appetite was good. Temperature 38*4° C. During the previous three 

 years four cases of purpura hsemorrhagica, three of which had ended 

 fatally, had occurred in the stable from which this patient came. 



Treatment. — Injection into the connective tissue of the neck of 

 three and a half fluid ounces of normal horse serum. During the five 

 following days four to four and a half fluid drachms of this serum were 

 injected in the region of the neck, over the triceps muscles, and into 

 the front of the chest. 



On the i6th swelling of the fore-limbs had diminished ; that of the 

 hind remained as before. There was little fever, the temperature only 

 rising a few tenths of a degree above normal ; appetite was preserved. 

 The treatment was continued. 



On the 19th the swelling in all four limbs was diminishing. 

 A trifling whitish discharge ran from both nostrils ; it continued for a 

 week. Serum was injected, and one and a half ounces of sodium 

 bicarbonate were administered on alternate days. 



The animal left hospital on the 31st March, the swelling of the 

 limbs having completely disappeared.

 Had been rested since the 25th November. On the 9th December 

 signs of purpura appeared. Was brought to the school on the evening 

 of the next day. 



State on Examination. — The limbs were swollen as high as the upper 

 third of the forearm and thigh. The left side of the breast and the 

 right of the abdomen showed oedematous patches ; the lower half of 

 the head was swollen ; the nose, face, lips, and cheeks were greatly 

 infiltrated. Blood-stained discharge ran from both nostrils ; the 

 mucous membrane of the nose exhibited blackish ecchymoses, almost 

 everywhere confluent. The respiration was 60 per minute and noisy ;
