REPORTS OF CASES. 
found some effusion, patchy peritonitis, bowels congested, kid¬ 
neys enlarged, stomach congested, spleen empty, flat and flabby 
and beautifully mottled with haemorrhagic infarcts. The ovaries 
were normal. The liver had an old cicatrix on it about one 
and a half by one inch in size, and a number of small elevations 
of Glisson’s capsule, as if gas had forced it out into minute 
elongated pouches. 
Upon opening the thoracic cavity a considerable amount of 
very foetid gas escaped. There was also some serous effusion 
here, patchy pleurisy and a pericarditis. The heart was en¬ 
larged and contained antemortem but recent clots. The lungs 
were filled and distended with a very foul sero-sanguinous fluid, 
which ran out when the lungs were cut and could be squeezed 
out like water from a sponge. There were large and innumer¬ 
able areas of gangrene, and were emphysematous. 
Upon opening the pulmonary artery I came upon my object 
of search. There we found a thrombus of a yellowish or 
grayish-white color, which I caught hold of and gently pulled 
upon, and was rewarded by drawing out a clot which showed 
the distribution of the blood vessels most beautifully and mi¬ 
nutely. I spread this out nicely on white paper and the clot 
shows the main trunk which represented the pulmonary artery 
and the right and left branches into both lungs and further 
subdivisions until it became as fine as the finest hair. 
It seemed almost impossible that a clot could get so tough 
as to have strength enough to allow it to be drawn out of the 
most minute blood-vessels. This toughness proves its age and 
in my opinion leaves no doubt as to the diagnosis made on my 
first visit. 
In conclusion, I will say that I based my diagnosis almost 
entirely on the very great distension of the blood-vessels, to¬ 
gether with a lack of completing symptoms of other apparent 
ailments, or, in other words, I diagnosed “by exclusion.” I 
figured that nothing short of a mechanical obstruction could 
cause such a condition of the blood-vessels and pulse ; along 
side of which a typical laminitis pulse, which I believe is our 
largest pulse, becomes a small wiry pulse in comparison. 
REMOVAL OF A CALLOSITY. 
By J. A. McCrank, D. V. S., Plattsburgh, N. Y. 
A few years ago Dr. W. purchased a driving mare. She 
was gentle, easily handled, perfect in every respect, barring a 
callous cicatrix on the front of the ankle on one hind foot,
