(S.) CYSTITIS, OE INFLAMMATION OF THE BLADDEE. 



Except as a result of the irritating effects of cantharidine or 

 croton oil absorbed from a blister, or administered internally, I 

 have never seen this affection in any of the lower animals, and 

 am disposed to coincide with many veterinarians, that it never 

 occurs except from the above causes. 



SymjJtoms. — These are manifested primarily by excitement, 

 followed by prostration of strength, the animal appearing to 

 suffer much pain and distress ; the urine is passed freq[uently, 

 and with difficulty and pain ; the fseces are covered with mucus 

 and mixed with blood. When induced by cantharides or croton 

 administered by the mouth, the inflammation extends throughout 

 the whole alimentary canal, and there is redness of the buccal 

 mucous membrane, with difficulty of swallowing, and attempts 

 at vomition in horses and cattle, the genito-urinary organs being 

 also much affected ; but if the above irritants be absorbed from 

 a blistered surface, their effect is concentrated upon the urino- 

 genital organs, causing in most animals strangury and ajDparent 

 sexual excitement, and if these symptoms are not soon allayed, 

 death will result in two or three days. 



Treatment. — If from a blister, wash and cleanse the blistered 

 part ; internally, hyoscyamus or opium, bicarbonate of soda, de- 

 mulcents, such as linseed tea, mucilaginous drinks, milk, and 

 white of e^n's wUl be found beneficial.

 urine contained in the bladder. It is caused by spasm of the
