ordered stomach, it then becomes also dangerous 

 to the animal, not merely as a disorder in itself, 

 but from its origin. 



There can be no doubt but strict attention to 

 the state of the horse's stomach is a very great 

 prevention of such attacks, for if simple megrim 

 is caused by effusion of blood to the head and 

 brain, that is wonderfully increased or diminished 

 by the state of the stomach ; and although many 

 horses will have frequent attacks of megrim (let 

 us do all we can to prevent it), if they were, 

 under such circumstances, frequently so attacked, 

 the recurrence would be much more frequent 

 without such precaution, of course. 



Harness horses are certainly much oftener at- 

 tacked by megrim than riding ones, doubtless 

 from the pressure of the collar. This in single 

 harness is very objectionable : for though an 

 attentive eye will generally detect the coming 

 attack, it is sometimes too sudden to allow time 

 to disengage the horse from the vehicle, and then 

 a breakage of some sort may be anticipated. 



There is one circumstance in this disorder 

 greatly in our favour. Horses are seldom at- 

 tacked with it when used by night ; and some 

 stage-coach horses, that would be certain to get 

 megrims if driven by day, and particularly with 

 the sun in their faces, will work in a night-coach 

 without ever showing symptoms of the complaint.
