. Chymistry applied to agriculture. Agricultural chemistry. CHYMIS APPLIED TO CHAPTER I. GENERAL VIEWS OF THE ATMOSPHERE, CONSIDERED IN ITS EFFECTS UPON VEGETATION. In order to judge of the influence which the atmosphere exercises over vegetation, it is necessary to be acquainted with the peculiar and characteristic properties of each of the elements of which it is composed, and to study their action upon terrestrial bodies. The gases, azote and oxygen, are the two fluids, of which the atmosphere is essentially composed; they are found in uniform proportions, even in the highest regions from which they have been brought. M. Gay-Lussac has established this fact, by a comparative analysis of the air taken from a height of twenty-three thousand feet, and of that which is upon the surface of the earth. There are certain other fluids, which are uniformly found in the atmosphere, but in very variable proportions ; the principal of these are carbonic acid, water, the elec- tric and magnetic fluids, light, and heat. The two last mentioned exercise a very marked influence, not only on vegetation, but on all the phenomena which terrestrial bodies present to our notice; and though they do not enter essentially into the composition of the atmosphere, their action is so closely united with that of its principal constituents, as to be nearly inseparable from them. In order that the action of the atmosphere may be better understood, I propose to treat separately of all the fluids it contains, and afterwards to show the phenomena which the application of them to agriculture exhibits. 1.
