Fixed, but Noxious Disinfectants. — These are dis- 

 infectants which, when mixed with manure, render it 

 valueless as such. 



1. Chloride of Zinc. (Burnet's Disinfectant Fluid.) 



2. Nitrate of Lead. (Ledoyer's Disinfectant.) 



3. Sulphate of Copper, and Zinc Solution. (Larnaudes.) 

 Chlorinated Soda Solution may be mixed with manure, 



without destroying its qualities as such. 



Chloride of Lime. Solid, or in powder, does not destroy 

 the manuring qualities of vegetal, and other materials 

 usually converted into manures. 



Diuretics. — Medicines, which, when given to animals, 

 increase the flow of urine. They are used in eases of 

 swellings and dropsies of the body and legs of horses. 



Elecauipane. — Lnula Helenium. The root of this plant 

 is highly thought of, and much used, by horsemen, in 

 coughs and colds. Some make a tea of it, or decoction, 

 and give it to the horse to drink. It is certainly a warm 

 and grateful aromatic, and a good expectorant. The plant 

 should be gathered when the seed is ripening. 



Elm Bark. — Slippery. This bark, when scalded with 

 hot wdter, makes a useful poultice for irritable wounds, 

 ulcers, and sores. A decoction of the bark will answer 

 every purpose for which flaxseed, or linseed is used, or 

 recommended, as in diseases of the kidneys, and bladder, 

 produced by the use of Spanish fly, and from over-dosing 

 with rosin, and other diuretics. In diarrhoea, in all ani- 

 mals, slippery elm tea, or decoction, will serve a good 

 purpose, by sheathing the covering of the bowels, which 

 is so apt to become irritated and inflamed in violent 

 superpurgation.
