 lameness, on which event he should not be exercised ; but let the parts be 

 poulticed with a turnip poultice, or it may be made of oatmeal and the grounds 

 of stale beer, or both may be employed alternately ; and then the parts, if luxu- 

 riant or thick, may be washed with a solution of blue vitriol in water, or the 

 wash, No. 3. Dress the cracks with the following 



Ointment. 



Oil of turpentine, 3 drachms. 



Hog's lard, 6 ounces, 



Litharge water, half an ounce. Mix. 



This may be varied by substituting Venice turpentine, half the quantity of 

 the oil. In these inveterate cases we have now under consideration, a change 

 of medicine is desirable, if but for the change which it occasions in the animal's 

 digestive powers; for this purpose the blue pill has been given as an alterative, 

 as well as that other preparation of mercury, the well-known Cvlomel. Both 

 act upon the kidneys, and set them in motion for ths production of urine; ?nd 

 calomel chiefly effects this, by previously stimulating the liver, uhkh again u 

 very desirable by way of change. 



Alterative Balls. 



Calomel, 1 1-2 drachms, 

 Aloes, 3 drachms, 

 Castile soap, 6 drachms, 

 Oil of juniper, 40 drops. 



Mix ; make into three balls and give one daily for a week ; but should it gripe 

 the animal, discontinue it, or add opium from half a drachm to a drachm. 



SURFEIT— MANGE. 



Both of these diseases of the animal's system, and the first-mentioned proves 

 its connexion with the second by sometimes ending in the mange. Over- 

 feeding, or too much of it, or gross feeding, as it is the cause of these twin dis- 

 eases, so are the two appellations it receives in the different stages of the at- 

 tack descriptive of the cause : both are of French origin, as I apprehend ; sur- 

 fait or overdone, being tantamount to mange, in its imperfect tenses, the 

 effect of eating too much, which has brought on the disease. A surfeit, or 

 sur-fait, is not an uncommon disease with reasonable man, and is alike caused 

 by eating improperly, if not too much, and sometimes from the preparation of 

 viands that are over-luxurious for the stomach that is to receive it. and is in 

 fact incapable of digesting it. This is a state of the stomach that is by no 

 means uncommon, and up to a certain extent happens every day to the full
