fibrous patches, which, however, were of earher date than the pulmonary 

 disease. The endocardium and valves of the right side appeared 

 unaffected. The great sciatic nerve of the right side was exposed 

 throughout ; its upper part displayed a few disseminated haemorrhagic 

 points. The spinal cord appeared normal. Microscopic examination 

 of the cardiac and nervous tissues failed to reveal the presence of 

 microbes, and inoculation of gelatin and agar with scrapings from 

 these tissues produced no growths. 



Remarks. — In equine pneumonia, quinine sulphate in doses of i-j to 

 2^ drachms, according to the size of the patient, repeated twice a day, 

 usually causes temporary lowering of temperature. Excessive doses 

 produce excitement and hyperthermia, as in Case 182, where the 

 animal was of medium size, and 2^ drachms was an overdose. 



185. A six-year-old entire horse, bought six weeks before, and left 

 in hospital April 2gth, 1899. Had been kept in a stable where out- 

 breaks of pneumonia were frequent. In consequence of an attack of 

 acute enteritis at the commencement of April it had been rested for 

 nearly three weeks. On the 27th April it showed symptoms suggestive 

 •of pneumonia, and was sent here two days later. 



State on Examination. — Seen in its stall, the animal seemed greatly 

 depressed, and hung back from the manger, with its head low and eyes 

 half closed. The conjunctiva was yellowish ; the mouth moist and 

 hot ; the artery tense ; the pulse feeble ; the cough small and paroxysmal. 

 Nothing was noted on auscultation or percussion. Respirations 26, 

 pulse 68, temperature 40'5° C. 



Treatment. — Mustard was applied to the chest, causing the tempera- 

 ture to fall eight tenths of a degree ; internally, alcohol, bicarbonate of 

 soda, and warm creolin enemata were prescribed, while 8 ounces of 

 normal salt solution were injected subcutaneously. 



On the 30th the condition was graver ; torpor, loss of appetite, and 

 injection of the visible mucous membranes were noted, and a dark line 

 had developed along the gums. Respirations 35, pulse 75, temperature 

 40'4° C. On auscultation the vesicular murmur extended over the 

 entire area of both pulmonary lobes. No abnormal sound could be 

 heard. Apart from its rapid action the heart showed nothing particu- 

 lar. The evening temperature was 40"6° C. 



On the ist May the general condition remained as on the previous 

 evening. Respirations 32, pulse 75, temperature 30*9° C. The con- 

 junctivae were saffron-yellow; the pulse feeble; there was abundant 

 rust-coloured discharge from the nose ; inspiration was oppressed, and 

 expiration sighing. Cough was frequent. On the left side the zone of 

 dulness extended as high as the point of the elbow. On auscultation, 

 crepitation and a slight tubal murmur could be heard. On the right 

 side the lower part of the chest revealed partial dulness, but no abnor- 

 mal sounds. The heart-beats were strong and slightly irregular. The 

 same treatment was continued, but a dose of digitalis was also given. 

 Sixteen ounces of "8 per cent, salt solution were injected. During the 

 following hours the temperature fell a few tenths. In the evening 

 •respirations 35, pulse 84, temperature 40*4° C.
