PULMONARY EMPHYSEMA IN A COW. 
By C. H. Sweet apple, V. S., Ontario Veterinary College, Toronto, 
Canada, 
Among the numerous post-mortem examinations that I am 
accustomed to make on cattle for butchering purposes in the 
city of Toronto, Canada, for the Health Department of the city, 
the following case may be of interest to your readers, as so 
marked a case of “ pulmonary emphysema ” in the ox tribe, 
and the animal otherwise in perfect health, is probably seldom 
met with. 
A short time ago I was called to the Toronto cattle market to 
examine a fat cow. Her respirations were very frequent, but not 
abdominal; temperature 102 0 F. ; pulse normal; healthy moist¬ 
ure on the nose ; auscultation revealed no mucous rales in the 
trachea or bronchi ; in fact, no abnormal sounds whatever 
that I could discover. On percussion of the thorax, I fancied 
that the right side was a little more resonant than the left. Blit 
there are certainly better places for auscultation and percussion 
than a crowded cattle market. There were no febrile symptoms 
whatever. 
The cow was ordered to be retained for a few days and 
then to be butchered under inspection, as it was probable that 
by rest and quietude for a short time her respirations might 
improve. Four days afterwards I again examined her at the 
slaughter-house. I found no change in the respirations ; they 
were quite as frequent as before, and all the other physical signs 
of health as before. I was told that the appetite and rumina¬ 
tion, as well as the evacuations from the bowels and kidneys, 
were normal. 
The animal was then butchered in the ordinary way, the 
viscera removed, and all carefully examined. 
There were no adhesions, abnormalities nor pathological 
changes of any kind that I could discover, with the exception 
that the greater part of the large lobe of the right lung was 
greatly distended with air (“ interlobular emphysema ”). The 
distension being much greater than the same condition in the 
horse, owing to the well known fact of the much greater amount 
of areolar tissue in the lungs of the ruminant. The carcass was 
well nourished and fat.
