PARTURIENT APOPLEXY IN THE COW.

and salt made to the poll, a solution of salt and water, io grains 
salt to 01 . of water, heated to the temperature of ioo° F. is in¬ 
jected into the jugular vein, the point of selection being the 
upper third of the neck. 
The apparatus used for this purpose is Dieulafay’s aspirator 
manufacturers, Codman & Chentleff, of Boston ; this is Patain’s 
modification of Dieulafay’s aspirator. 
The needle is introduced into jugular vein with point directed 
toward the heart. Care being taken that no air is allowed to 
enter, after the solution has been injected remove the needle, 
and the wound or puncture may be compressed with the finger 
for a moment, 
It is a physiological fact that the blood maintains a constant 
specific gravity, which if increased, the fluid relieves itself, by 
pouring out through its depurative passages the excess. 
In from twenty minutes to one half hour the pulse from slow 
and full becomes increased in action almost tumultuous; temper¬ 
ature rises to 102°. Respiration quickened, and bowels begin 
to move, the muzzle becomes moist, and later the body is bathed 
in perspriation. Purging may ensue, but I have seen but two 
cases where it became alarming and then it was checked in the 
usual way. The animal gets up, and although groggy and be¬ 
wildered for a short time, begins to notice and care for her calf, 
and to eat. I have found that one attack does not necessarily 
predispose an animal to another at the next time of her coming 
m, although if in the same condition at the time, I have seen it 
occur. 
I think care in feeding in plethoric cases is a wise precaution 
to take in avoiding an attack of this trouble. All grain should 
be withheld for a time before calving. This condition I have 
not witnessed in mares. In one case I attended it was a question 
between it and azoturia. 
As to the condition occurring during or previous to labor, I 
think the cases are rare. I have seen but two cases which oc¬ 
curred before and one during labor. In the first two, delivery 
was induced by artificial means, one recovered rapidly, while the
