THE EQUINE HOSPITAL FORMULARY. 37 



'At 10.15 a.m. — The dog now refuses food ; the swelling 

 increases, especially in the sub-labial region. Breathing 

 tliroucrh the nose becomes still more difficult : the comatose 

 condition is becoming more extreme. The breathing is very- 

 slow (9 in the minute). 



' At 10.20 a.m. — The swelling is increased. Eespirations 

 9, and laboured, but vary slightly. The swelling shows 

 ecchymoid patches, of a reddish-purple hue. 



'At 10.25 a.m. — ^The respirations number 12 per minute, 

 and are laboured. The swelling is still more marked. One 

 hind-leg is stiffened, and apparently partially tetanized. 



'At 10.29 a.m. — The animal is perfectly helpless, and 

 lies prostrate. The ecchymoid patches are more marked, 

 more purple, and are especially well shown near the teeth. 

 Both hind-legs are slightly stiffened, but movable. The 

 temperature is 99" F. 



' At 10.35 a.m. — The respirations number 8 per minute.

' At 10.45 a.m. — The animal is still capable of feeling, 

 since an incision, made to obtain a drop of blood, produces 

 pain, which is evidenced by a scream. The tetanus has 

 disappeared. The dog moves, there being, apparently, a 

 temporary revival. The swelling has extended on to the 

 cranium, and is more marked. Respirations 30 in the 

 minute. 



'At 11.15 a.m. — An incision was made with some sharp- 

 ness for the purpose of procuring a drop of blood for 

 microscopic examination. It is noteworthy that this 

 incision, unlike the one made at 10.45 a.m., was not felt 

 by the dog. A specimen of blood was then carefully pre- 

 pared with warm water. No abnormal appearances could
