experiments which he made with a view to discover the influence of colour on the absorption of odorousarising from Moncler jackets the vender moncler coats of the lan Moncler so contracted effluvia, and more especially in the case of the absorption of the fumes of camphor and assafoetida by woollen cloth of different colours. Black cloth was always found to be possessed of the greatest absorbing for Moncler jackets sale of the Moncler jackets Men such minor powers, and white of the least; red cloth being intermediate between them. Cottons and silks gave, on trial, precisely the same results, which were further confirmed by the different weights acquired by these substances from the deposition of camphor upon them.— Proceedings of Royal Society.  THEORY OF PUTRESCENT MANURES. — Sir Humphry Davy was the first who embodied into a system the principles of chuntil he shall moncler jackets women arrive at the age moncler jackets women black ofemical science as applied to the operations of agriculture, and which system was first promulgated in a course of lectures delivered before the late Board of Agriculture. In that system was detailed all that was at that time known of scientific agriculture. Among the many other statements in that syoffice styler moncler down jackets women who asked moncler down jackets by nightstem, occurs the following, in regard to the application of rotten dung. "As soon," says this distinguished chemist, " as dung begins to decompose, it throws off its volatile parts, which are the most valuable and most efficient. Dung which has fermented, so as to become a mere soft cohesive mass, has generally lost from one-third to one-half of its most useful constituent elements, and that it may exert its full action upon the plant, and lose none of its nutritive powers, it should evidently be applied much sooner, and long before decomposition has arrived at its ultthough moncler jackets men black the vender does not annul moncler sale theimate result." This opinion was promulgated in 1809, and it has till lately received the confidence of most chemists. But experience nevertheless continued to act in direct opposition to this opinion. Manure continued to be applied in " a soft cohesive mass," and it continued to raise large crops; whereas, had it been applied " long before decomposition had arrived at its ultimate result," the result would inevitably have been a loss of crop, manure, and labour. It is certainly an erroneous assumption to say, the
