quarters, where, after a stay of about ten days, the disease ap¬ 
peared in a pronounced form, and sheep began dying in con¬ 
siderable numbers. , 
The herd was a mixed one of ’1800 sheep, largely ewes, and 
240 Angora goats. About the i8th or 19th of May, the sheep 
began dying at the rate of two to four daily, and continued 
through June. During the investigations of a year ago it was 
thought that one or two Angora goats had died of the disease, 
but in the present outbreak none of the 240 goats, which com¬ 
mingled freely with the sheep, showed any signs of the malady. 
On May 30th post-mortem examinations were made on three, 
affected animals, the results of which follow. 
Case No. /.—An aged Merino ewe, about 50 lbs. weight, 
weak, and emaciated, was killed by bleeding. The subcutane¬

men contained three or four ounces of dark colored serum, liver 
slightly enlarged, yellow, firm; gall bladder distended with 
dark-green bile, the connective tissues surrounding the gall 
bladder infiltrated with pale, dirty-brownish serum. Alimentary 
canal was moderately filled with food and offered nothing of 
note except a well-marked dirty-brown effusion along the 
smaller curvatures of omasum and abomasum. Kidneys en¬ 
larged, dark, soft, and on section much blackish urine exuded ; 
bladder contained eight ounces dark-brown, semi-transparent 
urine. Uterus contained placental debris from recent parturi¬ 
tion. Spleen small, globular, contracted, black on section. 
Lungs normal, heart pale, flabby and empty. Facial sinuses 
contained six 'oestrus larvse. 
Case No. 2 .—Grade Leicester ewe, 75 lbs., down, unable to 
rise. Conjunctivse dirty-brown in color. Killed by bleeding. 
The blood flowed freely (black, thin and smeared on a glass 
slide appeared dirty-brown in color, quite devoid of the usual 
red). Subcutaneous connective tissue dark, dirty-yellow. 
Omental and mesenteric fat dirty, dark-yellowish brown, spleen 
small, firm, dark ; the liver large, dark in color, the lobules 
yellow, the inter-lobular spaces filled with blood which gave a
