 contains four grains of arsenic to the ounce. Very serviceable in chronic 

 rheumatism and skin diseases. Externally it enters into many dipping 

 mixtures for destroying lice and other vermin on sheejD. Nos. 77, 79,

 sheep, 1 drachm. Occasionally given to horses and cattle, for colic 

 and chronic coughs. Nos. 104, 105, 153, 154, 324, 403. 



Belladonna. — Dose of the dried powdered leaves, 2 ounces; 

 of the extract, 1 to 2 drachms. In influenza, sore throat, severe 

 colds, inflammation of lungs, and the like, this is a valuable remedy. 

 For sore throat, with noisy breathing and spasmodic cough in horses, 

 no other medicine gives such immediate relief. Excessive sweating, 

 from weakness, is promptly checked by a full dose. Externally it 

 relieves irritable and painful wounds, the raw surface following frost- 

 bite, cracks from mud fever, etc. Inflammation of almost any part of* 

 the eye is relieved by belladonna. Its active principle is atropia. This 

 can be very neatly administered with the hj^odermic syringe ; ten 

 drops, of a solution of five grains of atropia to the ounce of water, is 

 the proper strength for a horse, repeated as necessary. Nos. 77, 139, 

 157, 165, 264, 268, 273, 274.
