A CASE OF THROMBOSIS OF THE PULMONARY ARTERY. 
By E. E. Quitman, M. D. C., Chicago, Ill. 
During the evening of September 27th, 1901, I was called 
to the stable of one of my clients to see a mare about nine years 
old, weighing in the neighborhood of 1100 pounds, which was 
thought to have been “foundered.” 
The history of the case was that the mare had been idle for 
about four weeks, but had been at work for the past four or five 
days. Previous to this time she had never been sick or ailing 
during the time of her present ownership, which was over three 
years, her idleness being due to the owner having no use for her. 
She was noticed to be stiff in the morning, but I was not 
called until evening. On coming into the stable the attendants 
were found trying to move her, and my first impression, gained 
from her attitude and apparent disinclination to move, was that 
I had a case of laminitis, myositis, or muscular rheumatism, to 
deal with. But upon examining the pulse, which was my first 
step in the examination, I saw that I had something “ unique ” 
instead, and immediately put on my thinking cap. I found a 
pulse which was at least one-half inch in diameter, extremely 
resistant and beating like a trip-hammer. This in an exagge¬ 
rated sense also suggested lymphangitis. The accompanying 
vein was also immensely distended, but more compressible. 
I next examined all superficial blood-vessels and found all 
extremely distended and firm. Especially noticeable were the 
larger blood-vessels on the inner aspect of the limbs, both hind 
and fore, which seemed, at least, an inch in diameter. The 
mucous membranes were slightly injected, respiration rapid, 
about 50 to 60 per minute. Occasionally there would be mus¬ 
cular contraction of the trunk, as though affected with “shoot¬ 
ing pains,” lasting but a moment. 
Surface temperature was apparently normal, or higher than 
normal, temperature per rectum 104^° F. The limbs Were 
warm and lung sounds noirnal. There was apparently an 
inability for motion, but upon forcing the animal this proved 
to be a disinclination rather than an inability. On first attempt 
the mare would settle back on her hind quarters as if badly 
foundered, then getting started would act as though the front
