DISEASES OF THE GENITAL ORGANS. 



neoformations, chronic inflammatory processes of the vaginal mu- 

 cous membrane, of the uterus and Fallopian tubes. The treatment 

 of these accidents is essentially surgical. 



Incurable sterility is usually related to the absence of ovaries or 

 to alterations of these organs ; aplasia, hyperplasia, atrophy, cystic 

 or carcinomatous degeneration ; obstruction of the ovulary fossa 

 by a circumscribed peritonitis (in the mare) ; also membranous 

 neoformations, which cover up the ovary and prevent the exit of 

 ovules; absence or partial ablation of the uterus, aplasia, and 

 uterine atrophy ; hermaphrodism in twin gestations, hybridity, 

 etc. 



In the cow Eloire has produced artificial sterility by introducing 

 a foreign body (lead ball, pebble) into the uterus. 



ANOMALIES OF LACTATION AND ALTERATIONS OF 



THE MILK. 



Alterations of the milk are quite frequent in the cow. The 

 veterinarian is more often consulted upon that subject than on the 

 most commou diseases of the bovine species. Our present knowl- 

 edge on this question is particularly due to the researches of Fuchs, 

 Haubner, and Fiirstenberg. 



Their principal causes are : 



1. Irrational alimentation, either excessive or insufficient ; a bad 

 quality of food, or tainted. It is often the case with the cow that the 

 alimentary conditions differ considerably from the natural regimen. 



2. Gastro-intestinal catarrh, the general morbid conditions, and 

 cachexia. 



3. Diseases of the udder. 



4. Influences of an infectious kind (micro-organisms), thermic, 

 chemical, electric. 



Among these alterations there are some which interest public 

 hygiene and the sanitary police, because they may determine serious 

 accidents in man and the animals of our various domestic species. 



According to the standpoint accepted, we may establish a different 

 division. We have adopted the following : 



1. Anomalies of secretion : agalorrhea, watery milk, fat milk. 



2. Alterations due to external influences, especially to the action 

 of certain micro-organisms : curdled milk, milk not producing any 

 butter, mucous, putrid, blue, red, or yellow milk.
