PATUR!ENT APOPLEXY IN THE COW; A NEW METHOD OF 
TREATING THIS DISEASE SUGGESTED. 
By R. H. Harrison, D.V.S., Atchison, Kansas. 
A paper read before the Missouri Valley Veterinary Association, October 3, 1894. 
The practitioner having city or country practice is familiar 
with this condition among dairy stock, and knows with what 
poor results he successfully treats it. It is an affection of milch 
cows, and, as a rule, affects those that are plethoric and deep 
milkers, who have an easy, rapid labor. It is rare to see a case 
before, during or after parturition in a lean animal, although she 
may be a deep milker; or in a fat one, where the labor is diffi- 
cult and prolonged. 
Many theories have been advanced as to the cause of this 
condition, both in the cow and the state similar to it in woman. 
Lever, Braun and Frerichs ascribe the condition in woman 
to an excess of albumen in the urine, together with a retention 
of urinary elements in the blood ; this is not true of the cow ; in 
rare cases we have traces of albumen in the urine during preg¬ 
nancy occuring during the latter stage, but I have been unable 
to find any during the attack or after this disease. If the urine 
has been retained very long in the bladder,-it becomes very 
strong of ammonia. 
Other investigators consider the condition due to septic 
poisoning from the entrance, through lacerations in the os and 
cervix of septic material. I have seen but one case where an 
abrasion was found, although I always look for trouble, which is 
treated if found, antiseptically. 
All will agree with me that there is an increased arterial 
pressuie during pregnancy, and it is reasonable to suppose that 
when the foetal and maternal.circulation is so quickly discontinued,
