source of fearful irritation there, and it will lessen the gene- 

 ral fever which accompanies this stage of the malady. The 

 sheep must be removed, and its food changed. Mashes, 

 gruel, and a small quantity of hay, must be given. 



Two doses of physic must be administered, and then re- 

 course must be had to astringents. 



The purging medicines must not be discontinued, until 

 there is a perceptible alteration in the stools ; the doses, as 

 a general rule, should be small, and given for several days. 



The sheep must not be turned on the same pasture from 

 which it was taken ; let it be a dryer one. 



POISON. 



Sheep and calves will often, in the winter or spring of the 

 year, eat greedily of the low Laurel {Kalmia Angustifolia). 

 The animal appears to be dull and stupid ; swells a little, 

 and is constantly gulping up a greenish fluid which it swal- 

 lows down ; a part of it will trickle out of its mouth, and dis- 

 color its lips. 



The plant probably brings on a fermentation in the stom- 

 ach, and Nature endeavors to throw off the poison herb by 

 retching or vomiting. 



Treatment. — In the early stages, if the greenish fluid be 

 suffered to escape from the stomach, the animal most gene- 

 rally recovers. To efl'ect this, gag the sheep, which may 

 be done in this manner. Take a stick of the size of your 

 wrist and six inches long, — place it in the animal's mouth ; 

 tie a string to one end of it, pass it over the head and down 

 to the other end, and there make it fast. The fluid will then 

 run from the mouth as fast as thrown up from the stomach. 

 In addition to this, give roasted onions and sweetened milk 

 freely.*

ANATOMY OF THE LIVER. f 



It seems to be a law of comparative anatomy that the bulk 

 of the liver shall be in an inverse proportion to that of the 

 lungs. In the horse the lungs are necessarily capacious.
