26 INFLAMMATION. 



terrible attack of colic. They are useful only in 

 clysters. Glauber salts have no better or more cer- 

 tain effects. Castor oil, mild and harmless as it is in 

 the human being, is in the horse seldom to be relied 

 upon where an immediate result is desired. Linseed, 

 olive, and neafs-foot oils are better things; they will 

 rarely do harm, but they are improved in their action 

 by a drachm of chloroform being added to the pint 

 dose of either. Almost the only purgative that can 

 always be depended upon is Barbadoes aloes. 



There has been a great dispute about the kind of 

 aloes. The Cape is the cheapest, and the Barbadoes 

 usually the dearest. The Barbadoes are the most cer- 

 tain in their effect, and can alone be depended upon. 

 The Cape will sometimes gripe, but the Barbadoes 

 will less frequently do so. 



The following will be a good physic mass, though 

 the animal being subjected to constant work is more 

 likely to be ill through exhaustion than to be dis- 

 ordered by repletion. 



RECIPE (No. 1). 

 Physic Mass. 



Take — Barbadoes aloes, very finely powdered, fifteen pounds ; 



Ginger, powdered, one pound ; and 



Soft soap, seven pounds and a half: 

 Beat them well together, and keep them in a jar closely covered. 



A very mild ball of this mass will weigh three 

 quarters of an ounce ; the quantity may be increased 

 to an ounce and a half, beyond which the dose should 

 not be carried, except under the direction of a prac- 

 titioner.
