MEDICAL TREATMENT OF DOMESTIC ANIMALS. 449 



*' back. In a few minutes the pain seems to cease, the horse 

 " shakes himself and begins to feed ; but on a sudden the spasm 

 " returns more violently, every indication of pain is increased, he 

 " heaves at the flanks, breaks out in a profuse perspiration, and 

 " throws himself more violently about. In the space of an hour 

 " or two either the spasms begin to relax and the remissions are 

 " longer in duration, or the torture is augmented at every paroxysm, 

 " the intervals of ease are fewer and less marked, and inflam- 

 *' mation and death supervene." 



Youatt also gives the following tabular statement of the symp- 

 toms by which colic and inflammation of the bowels may be dis- 

 tineuished from each other: — 



"Sudden in its attack, and without any 

 warning. 



" Pulse rarely much quickened in the early 

 period of the disease, and during the in- 

 tervals of ease, but evidently fuller. 



"Legs and ears of natural temperature. 



" Relief obtaine4 from rubbing the belly. 



" Relief obtained from motion. 

 "Intervals of rest and ease. 

 " Strength scarcely affected. 



INFLAMMATION OF THE BOWELS. 



Gradual in its approach, with previous indi- 

 cations of fever. 



Pulse very much quickened, but small, and 

 often scarcely to be felt. 



Legs and ears cold. 



Belly exceedingly painful and tender to the 



touch. 

 Pain evidently increased by motion. 

 Constant pain. 

 Great and evident weakness." 



With reference to colic, inflammation of the bowels, and in- 

 flammation of the lungs, Herbert says, — 



" Colic is usually produced by sudden cold, often the result 

 "of drinking cold water when heated ; sometimes by exposure to 

 "cold wind in a draft, when heated; sometimes by overfeeding 

 "on green meat or new corn. The causes of inflammation of 

 "the bowels are somewhat similar, though not identical. Horses 

 "used to high feeding and warm stabling, which, after sharp exer- 

 " cise and being for some hours without food, are exposed to cold 

 " wind, or are allowed to drink freely of cold water, or are 

 " drenched with rain, or have their legs and belly washed with cold 

 " water, are almost sure to be attacked with inflammation of the
