of comparatively immense doses of them, which in all probability arises from the 

 peculiar structure of his stomach. 



Wheat and Barley have been designated as poisons to this animal ; and occasionally 

 they have proved to be so, by setting up acute gastritis. A very common sequela of 

 poisoning by Wheat is inflammation of the laminsB, the result of metastasis ; and of 

 Barley, a depilation of the sldn. We are, however, in want of more correct information 

 than at present we possess, before anything definite can be laid down under this head, 

 as both wheat and barley, given in moderate quantities and with judgment, often prove 

 beneficial. 



I am induced to pass the agents above enumerated thus cursorily over, my object 

 having been to give a condensed and tabular view of such substances as are known to 

 destroy life in the horse when incautiously or maliciously administered, and to elucidate 

 a Thesis on Poisons which I had the honor to read before the Members of the Veteri- 

 nary Medical Association in 1836 : at the same time, I hope that this attempt may 

 prove of some use to the Student of Veterinary Medicine.
