of reasons, and is much more common during the first half of the normal 
period than in the latter. It may be sporadic, that is, induced by acci- 
dental or local causes, as atmospherical iufluences, such as bad weather, 
*nd irregular seasons — severe suddenly succeeding mild weather. Cold 
■tonns, etc., are especially to be guarded against. As external causes, 
access by the male, explorations in vagina, surgical operations, throwing 
the animal down, bleeding, and bad or improper food, are among the 
most common of external causes. Excitement, fear, surprise, certain 
odors , contagion, are credited with playing an active part in this dis- 
ability. Various diseases are also active parties in this direction. When

known causation, it may be enzootic or epizootic. Ravages of this kind ar»

drugs to be kept for that purpose ; they may be referred to at will. Iso- 
lation, however, is of absolute importance, lest the cause extend to other 
or perhaps all the cows in the stable. Ergot or other fungus spores in 
the food may be the cause. All possible causes should be carefully ex- 
amined and remedied. A thorough cleansing of the stables should bo 
made, and disinfectants and fumigants used. The following in the form 
ef powder is good as a disinfectant in any case.

Milk Fever. 
This fever occurs from the first to the third day after calving; rarely late* 
than this time. Select breeds and cood milkers seem specially liable to attacks 
from this disorder. 
The primary trouble in this disease is inflammation of the lining membranes 
of the womb, extending sometimes to its substance. and adjacent parts ; and in
