 abundance of easily decomposable animal matters.* 



The urine of the horse is nearly as rich in animo-vegetable 

 matters ; its composition, according to the experiments of Fourcroy 

 and Vauquelin, is as follows: —

It would appear, from some experiments of Dr. Belcher, that 

 the ammoniacal salts of urine have a forcing or stimulating power 

 which considerably hastens the vegetation of plants. His ex- 

 periments were made with the common garden cress ; and, in his 

 trials, some plants nourished with a solution of phosphate of am- 

 monia were fifteen days forwarder than plants growing under 

 similar circumstances, but watered with plain water. In some 

 experiments of Mr. Gregory, who watered half a grass field at 

 Leyton with urine, the portion thus treated yielded nearly double 

 the quantity of hay produced by the other unmanured portion ; 

 and the use of the urine of the cow, so extensively employed for 

 grass lands, and in the garden and orchard, by Mr. Harley, 

 in the neighbourhood of Glasgow, was attended with results 

 equally satisfactory, producing, when diluted with water or 



* The respective properties of animal urine depend much upon the nature 

 of the food upon which the creatures are nourished ; and its effects upon 

 the land are consequently different : thus, it has been found weaker when 

 taken from cows fed upon white turnips than upon Swedes, and still 

 weaker from cut grass ; while that produced iu the distilleries is com- 

 paratively better than either of the former. — F, Burkij. See Quart. JourOi
