ACUTE DYSPNCEA.

tongue with cyanosis of the visible mucous membranes ; as¬ 
sociated with these was a rattling tone, emitted both upon in 
and expiration. 
Case II. An eight year old gelding of the better breed, 
became sick with a bronchial catarrh, which terminated 
favorably within a week. During the disease the general 
health was disturbed but in a slight degree. From the 6th to 
the 8th days the patient could be led in the open air; the ani¬ 
mal being so lively, and his actual condition not speaking to 
the contrary, it was deemed advisible to harness him to a 
wagon. I left directions that in two days the horse might be 
used for his usual task. Before 7 o’cloek on the second day 
after this disposition of the case, I was informed that the 
horse was threatened with suffocation. At my arrival I 
found him perfectly sound, and by the most painstaking in¬

could discover nothing of a morbid nature. On the same day 
about noon the attendant came with the same word, and the

This was half consumed with great eagerness and appetite, 
when the horse moved suddenly back from the trough, and with 
separated limbs, distended head, and dilated nostrils, concen¬ 
trated his thoracic and abdominal muscles in efforts at respir¬

The heart pulsation could not be felt, but the movements 
of the flank numbered 60-65 per minute; anal movements 
were also present, from the heavy breathing. Eyes were 
widely open, and indicated great anxiety ; mucous membrane 
of the nose and mouth were cyanotic; the gluteal region was 
covered with perspiration which rolled in small streams down 
upon the limbs. 
Before I had concluded what should be done, the symp¬ 
toms suddenly ceased, so that in less than ten minutes the at¬ 
tack was past. Gradually the breathing became more quiet 
and the animal observed his surroundings with a blank stare ; 
the sweat was removed and in a few minutes he ate the bal-
