obstruction to the flow of milk. Their presence in the teat 

 can be readily detected, and they can usually be removed 

 by gentle manipulation, etc. 



Excoriation of the Teats. — The teats are frequently 

 excoriated, by coming into contact with long damp grass, 

 exposure to cold, etc, and such a condition may lead on to 

 mammitis. 



Treatment. — The teat should be handled very carefully 

 when milking the animal, and soothing and astringent 

 ointments should be used ; and sometimes it may become 

 necessary to remove a teat. Occasionally a large swelling, 

 partly of an inflammatory character, may be observed, 

 situated near the upper part of the udder. The practitioner 

 should be very careful as to the course of treatment, as 

 the enlargement may be due to the presence of hernia — a 

 condition occurring very easily in this region, as here the 

 abdominal walls are very thin. The cow should be cast 

 and secured, after which the parts may be opened very 

 carefully, and explored with a probe, as the enlargement 

 may be due to the presence of an abscess, or an abscess 

 coexisting with hernia. In either case give such treatment 

 as the condition seems to demand.

 AZOTURIA. 



AzoTURiA belongs to the class of dietetic diseases, and 

 may be defined to be a hyper-nitrogenous condition of

 the hind quarters, and has often been mistaken for a renal 

 affection. Percivall termed it ' albuminuria.' It is also 

 know as 'enzootic haematuria,' 'hjsteriti,' etc., and by the
