DISEASES OF THE DIGESTIVE ORGANS. 22) 
ubject, by way of prevention, is to give tone to the digestive or- 
gans ; and soon after the worms have congregated in the intestinal 
canal, bitter tonics and alteratives are obnoxious to them. They 
then die, are digested, and pass from the anus as fecal matter. 
Suppose we give the infested horse powerful purges, tartar 
emetic, calomel, turpentine, etc., as the books recommend. We 
may succeed in their expulsion, but that does not mend the mat- 
ter for the agents just named are all more or less prostrating, 
and create a worse state of digestive derangement than that which 
previously existed, and soon, by virtue of spontaneous generation, 
8 new crop of parasites make their appearance. 
When a horse shows any of the symptoms here alluded to, in- 
dicating indigestion, or the actual presence of worms, I recommend 
that an occasional dose of the following be given: 
Powdered sulphur..... cc. seccccesecceres 
xrowdered salt .....0.ee000- ie ais e/atweis ues 
Mix. 
Dose, one table-.poonful, to be mixed with bran or oata,

EXAMPLES OF VERMIFUGES. 
No. 1.—Fluid extract of wormwood, four drachms ; to be given 
in the morning, before feeding time, for several successive days. 
No. 2.—Give one ounce of fluid extract of pink-root, every 
morning, before feeding, for a week. 
A GOOD REMEDY FOR THE TAPE-WORM. 
Give four drachms of the solid extract of male fern (aspidium 
felix mag) every other morning, during a period of about ten days, 
This is said to be a specific for tape-worm. 
Finally, as regards the treatment of worms, Nature has endowed 
these parasites with such tenacity of life, that no matters knowr 
to us will effect their destruction, though a few may answer the 
purpose of their expulsion. Bots are so hardy as apparently te 
survive immersion in oil, in alcohol, spirits of turpentine, and 
even powerful solutions of mineral acids. The continued use of 
salt, mixed with the food, appears, however, obnoxious to them; 
for sometimes, under its use, their hold gives way, and they are 
eiected. Ditters, purgatives, and the mechanical irritation of
