THE HORSE, ITS DISEASES. 437 



So. 176. 2 Ounces chlorate of potash, 



4 Ounces powdered ginger. 



3 Ounces gentian, 



2 Ounces podophyllin, 

 6 Ounces poplar bark. 



Give also with the food, once daily, 2 ounces phosphate of lime. 

 JRub upon the swelled face with moderate vigor, twice daily, the fol- 

 lowing preparation : 



No. 177. 6 Ounces spirits of camphor, 



4 Ounces cod liver oil, 

 2 Ounces oil of cedar, 



1 Pint diluted acetic acid. 



If the case has been neglected until there are already breaks in the 

 skin, and exudation of matter, adopt the previously described course, 

 with this exception, that the part must be thoroughly cleansed with warm 

 soap and water, and then, instead of No. 177, apply the camphorated 

 corrosive sublimate every other day for six or eight times, then omit 

 three days, and begin again, and so on until the skin shows signs of heal- 

 ing. Apply the sublimate with a little mop of soft rags, and dry it in 

 with a hot iron held near the part, or pressed smoothly over a layer of 

 intervening cloths, thick enough to prevent actual burning. 



n. Sweeny of the Shoulder. 



The common effect of all lameness and disease of a limb is a wasting 

 of the muscles connected therewith. Therefore in all sprains entailing 

 inflammation and continued disease of a limb, and in all injuries entailing 

 chronic, long-continued manifestations, there will be wasting or atrophy 

 of the muscles, and in extreme cases sometimes permanent contraction, 

 even of the cords of the limb. This is popularly called swinny or sweeny. 

 It is the result of disease and not the disease itself. The cause of this 

 wasting must therefore be looked after in order to obviate the difficulty. 



There is, however, from sprain of the muscle outside the shoulder 

 blade, a tendency to waste of the muscles, to such a degree sometimes, 

 that they are so shrunken as to cause the skin to bo drawn tight to the 

 shoulder blade. 



Causes. — Sweeny is usually acquired by young horses, when first put 

 to work, from over-strain ; or, it may occur in horses of any age, from 

 hard pulling on uneven ground, by stepping into holes, etc., thus causing 

 injury to the muscles of the shoulder, and particularly those supporting 

 the joints.
