the same, so that one migTit be liable to suspect tKe occur- 

 reDce 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- 

 sibility 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 : 



COLIC. 



Sudden in its attack, and Without 



any warning. 

 Pulse rarely much quicljened in the 



early period of the disease, and 



during the intervals of ease, but 



evidently fuller. 

 Legs and ears of natural temper- 



Boiief obtained from rubbing the 



belly. 

 Eeliei" 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 

 u)arked 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 convenientl^elt at the lower jaw ; a little behind 

 th-j s[)ot where the submaxillary artery and^ein 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 parsing. under and
