other nauseating medicines was followed by increased uneasi¬ 
ness and manifestation of gastric irritation and nausea, and that 
these symptoms do not follow the administration of the same 
dose where the stomach is not thus affected ; and again that 
such symptoms generally follow the administration of such- 
medicine in cases of parturient apoplexy, and patients became 
rapidly worse, and the constant returning of the fluids from 
the stomach into the throat, while the animal is lying flat, 
produce fatal strangulation, more often than when taking the 
medicines in the first place, if they be carefully administered 
while the head is elevated and the body propped up. No 
moie is the loss of the power of deglutition a symptom of 
parturient apoplexy than it is a symptom of the impactions, for 
in either case there is more or less paralysis of the entire 
alimentary tract. 
True, if we ascribe indigestion as the cause of all these 
cases the question naturally arises why are all the cases oc- 
cuiing at this peiiod accompanied with so much derange¬ 
ment of the nervous system, or why are not these complica¬ 
tions a more constant symptom at other times ? It must be 
admitted that at this time, in the history of all animal exiS' 
tence, there is something within the system which predis¬ 
poses, or aids to a derangement of the nervous system. 
The theory of nervous shock” weakening the brain and 
rendei ing the organ an easy prey to disease, is certainly up¬ 
set by the fact that the disease rarely if ever occurs after a pro¬ 
longed 01 difficult labor, in which the nervous system would 
be for a considerable time greatly taxed, but, on the other 
hand, follows easy and perfectly normal deliveries. Neither 
can we favor the theory of non-diversion of the blood from 
the foetus before birth to the mammary glands after birth. 
rushing to the brains,” for, in many instances to my per¬ 
sonal knowledge, there has been quite an abundant flow of 
milk, which would suddenly cease as the other symptoms 
made their appearance. Prof. Williams says, “ When the 
symptoms of the malady are not manifested for some time 
after the birth of the calf, it will generally be found that the 
secretion of the mammary gland has been in an average or
