COLIC.

fche same, so that one miglit be liable to suspect the occur* 

 rence of either, from a knowledge of the antecedents to 

 which the horse has been exposed, it was well done in 

 Youatt to present briefly in a tabular form the distinctions 

 between the symptoms of the two, which, if carefully ob- 

 served, cannot be misunderstood, and will prevent the pos- 

 Bibility of confusion, which might lead to the most fatal 

 consequences. We proceed to present his table, accom- 

 panied by his remark that the treatment recommended for 

 the former (colic) would often be fatal in the latter : 



Sudden in its attack, and without 

 any warning. 



Pulse rarely much quickened in the 

 early period of the disease, and 

 during the intervals of ease, but 

 evidently fuller. 



Legs and ears of natural temper- 

 ature. 



Relief obtained 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 pre- 

 vious indications of fever. 



Pulse very much quickened, but 

 small, and often scarcely to be 

 felt. 



Legs and ears cold. 



and 



Belly exceedingly painful, 



tender to the touch. 

 Pain evidently increased by motion. 

 Constant pain. 

 Great and evident weakness. 



Of these differences the most strongly and decidedly 

 marked are the different affections of the pulse, the differ- 

 ent conditions of the extremities, the remissions of the 

 pain in the one, and the constant increase of it in the 

 other, and the extreme weakness which rapidly comes on 

 in inflammation, and does not show in colic. 



It will be well, here, to state that the pulse of the horse 

 is most conveniently felt at the lower jaw ; a little behind 

 the spot where the submaxillary artery and vein and the 

 parotid duct come from under the jaw: in other words, 

 close to the junction of the head and neck. The thumb 

 should be placed on the cheek externally, with the nail 

 upward, and the tips of the fingers passing under and
