PURPURA HEMORRHAGICA. 497 



ounces of normal horse serum were injected ; six and a half ounces of 

 sodium sulphate and three and a quarter ounces of alcohol were given 

 in the drinking-water. During the night the difficulty in breathing 

 increased, and tracheotomy had to be performed. 



On the nth the general condition remained stationary. The 

 breathing, however, was easier, and much less rapid than on the pre- 

 vious evening. Temperature 39"o° C. During that and the next day 

 four and a half fluid ounces of normal horse serum were injected in 

 three separate quantities. 



On the 13th the head and fore-limbs were less swollen ; the oedema- 

 tous patch on the thorax was undergoing absorption ; that on the 

 abdomen remained as large as before, and had extended to the sheath. 

 An oedematous zone of considerable size had developed around the 

 tracheotomy wound. Temperature 3g'0° to 39'5° C. The injections 

 of serum were continued. 



During the three following days the head continued to diminish in 

 size ; the swelling in the limbs remained stationary ; the patch on the 

 neck gravitated towards the breast, and increased ; whilst that on the 

 abdomen advanced beneath the thorax. Temperature 38'5° to 38*8 C. 



On the 17th the swellings about the front of the body had greatly 

 diminished, as had those on the hind limbs and abdomen. The 

 tracheal tube was removed, and the wound swabbed with 20 per cent, 

 iodine solution. Temperature 39*0° to 39*3° C. Treatment was sup- 

 plemented by the daily administration of two ounces of sodium bicar- 

 bonate. 



On the 22nd the oedema had almost disappeared at all points ; tem- 

 perature 38*0° C. The serum injections were discontinued ; the 

 patient was exercised night and morning. 



A week later it had entirely recovered. 



189. An eight-year-old entire horse, left in hospital December i8th, 

 1897, to be treated for bronchitis. Double pneumonia afterwards 

 developed ; its onset was insidious, but the real nature of the disease 

 was clearly shown by the moist crepitation and tubal murmur on both 

 sides, and by the dulness of a considerable area of both lungs. 



The pneumonia commenced on the 8th January. On the 22nd the 

 temperature still varied between 39-0° and 39*6° C. Cough persisted, 

 and was accompanied by a double-sided muco-purulent discharge, in 

 which streptococci and some staphylococci were found on bacterio- 

 logical examination. The appetite was capricious. Percussion 

 revealed dulness over the anterior part of the right lung. On auscul- 

 tation moist rales were heard. A patch of chronic pneumonia was 

 suspected. The principal drugs used were iodide of potassium and oil 

 of turpentine. 



On the 27th the hind limbs were swollen, and an oedematous patch, 

 as large as a man's hand, appeared on the right side of the abdomen. 

 The Schneiderian membrane showed a few petechias. Temperature 

 38*9° C. ; respiration 17 ; pulse 40. 



Trmf7;?^n^.— Subcutaneous injection of three. and a quarter fluid 

 ounces of normal horse serum. •
