accuracy, is under the jaw, where the sub-maxillary 

 artery can be pressed against the bone. As the 

 position of this artery is only known with certainty 

 by the anatomist, it may guide the touch to direct the 

 finger along the inside jaw, a little above the edge 

 where it begins to decline downwards, gently press- 

 ing it against the jaw till the pulsation is felt. By 

 doing this two or three times, any man will soon dis- 

 cover the exact spot where he should feel for the pul- 

 sation. In a healthy horse, the intervals should be 

 about 40 or 45 per minute. When it exceeds this 

 by ten or twelve pulsations, the horse is not well ; 

 but the circulation may be momentarily accelerated 

 even to that extent, by sudden alarm ; it is there- 

 fore expedient to approach the horse quietly, and to 

 caress him for a minute or two at first, if he shrinks 

 from approach. If the pulse exceeds sixty, prompt 

 and scientific attention is indispensably required.
