    function is of a higher order. It is more particularly in the grain that this accumulation becomes striking by its constancy and by the quantity of products thus condensed. In the bean, the solid matter amounts, according to Braconnot, to as much as 25 per cent.; in the pea and the horse-bean the quantity may reach 20 per cent. The comparative analysis made by M. Boussingault of the grain and straw of wheat and of oats clearly demonstrates this law of decrease. In 1000 parts are found : Wheat Phosphoric Acid. - 9'64 Nitrogen, 1970 Wheat straw - - - i'6i 3-80 Oats - - 473 i9-oo Oat straw - - rc>7 3'°° There exists, as is seen from the above, a close connection between azotised matter and phosphoric acid in the organic world. These relations had long ago been brought to notice by M. Boussingault: “ Generally the alimentary substances the most azotized are also the richest in phosphates, which would appear to indicate that in the products of vege- table organization the phosphates belong to the azotised principles, and that they follow them in the organization of animals.”—“ Economic rurale,” tome P- 353- A few years later, M. Mayer formulated as follows the results of his researches on the same subject: “ There exists a remarkable relation between the albuminoid substances and the phosphoric aeid con-
