Diseases of the Respiratory Organs. 25 
“The disease showed itself during a remarkably cold 
spell; indeed, for the first three weeks of the epidemic the 
thermometer was almost constantly below zero. It was 
first observed in two or three pups of four conples which 
were kept by themselves in a separate room, 14ft. by 8ft. ; 
the floor being covered with straw, which was changed 
every week. There was a cupboard in the room, and in 
this the pups slept. This room was on the exposed side of 
the house, and, according to the keeper, was always very cold. 
The rest of the animals were kept in tolerably roomy 
quarters, though at night, with the doors closed, I do not 
think the ventilation would be sufficient. During the day 
they had free access to a large yard. The food consisted 
of porridge and cooked horseflesh, which were given either 
separately or boiled together. They got nothing else. 
The oatmeal was of good quality, nor did I find in portions 
of the food removed from the feeding-pans anything which 
afforded the slightest clue to the origin of the disease. 
“ Pathology.— Post-mortem examinations were made in 
eight cases. The following notes were dictated at the 
time : 
“CASE 1.—Autopsy eighteen hours after death. Body 
that of a well-nourished, half-grown, fox-hound bitch. On 
opening the thorax the lungs only partially collapse; the 
lower borders of the lobes are firm to the touch and dark in 
colour. The vessels in the lower mediastinum look 
full, and the tissues in that region are blood-stained. 
Pericardium natural; heart appears of normal size ; 
right auricle filled with dark grumous clots, which extend 
into the vessels and are here decolourised. Right ventricle 
distended with dark, semi-coagulated blood; the conus 
arteriosus is filled with a perfectly decolourised clot, which 
passes into the pulmonary artery to the third and fourth 
divisions. The left auricle contains a small coagulum. The 
left ventricle contains no blood, but the whole cavity is 
occupied by a firm milk-white thrombus, which is connected
