but drank freely. The condition on the 6th of July 
about the same, and on the 7th the animal ate a little b 
mash in the morning and noon, drank freely and seem 
to be somewhat better ; but in the evening the animal bt 
came worse—pulse 94, respiration 92, and the temperature 
dropped down to 98-f 0 —and finally died at 2 o’clock A. M., ap¬ 
parently with heart-failure. 
A post mortem was held in the morning of the 8th of 
July, and on opening the thoracic cavity we found that the 
latter contained about 6 gallons of a brownish-looking fluid ; 
the heart looked externally just like a big lump of curdled 
milk, showing extensive lesions of pericarditis. Internally 
the heart looked just as if it were boiled, showing anaemia of 
the heart, and in the left auricle and right ventricle we found 
large ante mortem clots. On close examination of the tho¬ 
racic cavity we found large ante mortem clots in the pos¬ 
terior aorta extending even into the branches of the iliac 
arteries and its branches. On opening the abdominal cavity 
we found a clear looking fluid, a dropsical condition, due to 
weakness and debility of the animal; the liver was of a 
dark blue color, showing everywhere the lack of circulation 
and its consequences. The animal apparently died from 
heart-failure, caused by various clots in the different cham¬ 
bers of the heart and general circulatory apparatus.

DOUBLE INTESTINAL INTUSSUSCEPTION IN A DOG. 
A Scotch collie dog, in an emaciated condition, had per 
sistent diarrhoea of six months standing. When seen had a 
prolapsus of the rectum probably about three inches, swollen 
and inflamed. On palpation is found an invagination of the 
posterior part of the colon, extending forward about eight 
inches. External manipulation failing to reduce the prolap 
sus, the animal was etherized, the abdomen opened and a
