EXTRACTS FROM EXCHANGES. 779 
the lesions of the left iliac were due to a rather uncommon 
cause. In an animal, which had presented the progressive 
manifestations of intermittent lameness of the left and after¬ 
wards of both hind legs, and whose symptoms were evidently 
those observed in aortic embolism, the post-mortem revealed 
the startling cause of the arterial disease. A tumor of sarcoma¬ 
tous nature surrounded the right kidney, involving the aorta 
on a level with the renal arteries. The kidney itself was free 
from any alterations, but the aorta had lost its supple condition ; 
its external coat was red, eroded, and rough, and at its termina¬ 
tion contained a clot which extended into the iliac arteries, 
which were double in size. The walls of the aorta were ossi- 
fied. The sarcoma in modifying the walls of the aorta and 
giving rise to endarteritis had promoted the formation of the 
thrombp. The clot, loose in the cavity of the vessel, had 
moved, into the iliac and there given rise to the formation of the 
embolism, fatal cause of the incurable lameness of the patient. 
Chorea oe the Diaphragm in a Cow. —Spasms of the 
diaphragm are of common occurrence in horses, but their 
presence in cattle is rather rare. From the “ Notes of a Prac¬ 
titioner ” the Reciceil publishes an interesting case observed in 
a Normandy cow in an advanced state of pregnancy. When 
called to examine her the author of the note found her in an 
apparently perfect condition of health, almost ready to calve, 
pulse strong and regular, temperature normal defecation and 
micturation normal ; appetite good, rumination perfect. No¬ 
thing abnormal in respiration, heart normal, foetus alive. Given 
hay, she took hold of it with an appetite and after a few minutes 
a sudden spasm was observed at the flank. This soon increased, 
became stronger, more marked and repeated. At each inspira¬ 
tion, the flank was raised by a sudden powerful jerk, shaking 
the whole body. The ribs were projected outwards, the expira¬ 
tion short, the respiration increased, rapid, and accompanied with 
marked roaring. The animal seemed suffering with violent 
hiccough. These symptoms were truly alarming, and still the 
animal kept on eating. The hay was then taken away, and as 
the prehension of the food ceased the symptoms diminished and 
disappeared, to return as soon as the same food was given 
again. The^ treatment was all indicated. A change of 
diet. The animal was fed to the end of her delivery with food 
of easy digestion, her ration was carefully measured, the hay 
entirely suppressed. After delivery the animal was gradually 
brought back to her ordinary diet and continued in perfect health.
