increased to six grains, and continued until the cough 

 abates and the condition of the horse has improved; or 

 the ergot of rye may be used internally, as a substitute 

 for the iodide of potash. 



The brain of a horse that dies of glanders, is some- 

 tiroes wholly changed to a sort of gangrenous matter; 

 or near the base of the brain there will appear a sack 

 filled with the same. Veterinarians have bored through 

 the frontal bone of the face for the purpose of letting out 

 the matter collected in the cells and sinuses of the head, 

 without any injuries resulting to the horse. Shepherds 

 have been successful in curing what they call water in 

 the head of sheep, by running a sharpened wire up the 

 nostrils, through the sack that contained this water on the 

 brain, and thus let it out; and sometimes they have bored 

 through the skull for the same purpose with equal suc- 

 cess, penetrating the brain in both instances. The brain 

 of a horse may be bored into, or cut, or even a part of 

 it extracted, without destroying the life of the animal. 

 You may cut the brain without producing any sensation 

 of pain to the horse, notwithstanding you hurt any other 

 part, while at the same time the brain being the seat of 

 pain. Why, says some one, this is a very broad asser- 

 tion. Very well, 1 know it involves the question again 

 of this organ being the motive power, or the originator 

 of all the motions of the limbs, &c., which might be car- 

 ried much farther than my time or purpose would admit 

 of here. But if it were not for the sensation produced 

 by this organ on other parts, it would not produce pain 

 to cut off a leg any more than it would to cut off a stick 

 of wood.
