solution vegetable or animal matters, as the dung of animals. 

 Now these matters contain carbon, hydrogen, oxygen, 

 nitrogen, and various salts : the three first are absolutely 

 necessary for the existence of all plants, every part of these 

 is composed of them ; nitrogen is found in some plants ; 

 and the importance of salts to vegetation is demonstrated by 

 the facts, that clover will not flourish where there is no sulphate 

 of lime, that nettles follow the footsteps of man for the nitrate 

 of potass, which always abounds near the walls of his habit- 

 ation, and that marine plants linger for the common salt of their 

 native haunts. Salts of some kind or other are found in 

 every species of plant, but none that have not also been 

 detected in soils. During decay, vegetable and animal matters 

 exhale various gases. Carbonic acid, hydrogen, carburetted 

 hydrogen, ammonia, &c, are of the number ; all of which 

 have been applied to the roots of plants with great benefit by 

 Sir H. Davy and others.

 treading the steps of his estimable predecessor, in improving
