The ash of the husk differs, in consisting chiefly of common salt, phosphate of lime and magnesia." The analysis of the ash of the Peanut, furnished to the _American Agriculturist_, by H. B. Cornwall, Professor of Analytical Chemistry in the John C. Green School of Science, College of New Jersey, Princeton, and published in that Journal for July, 1880, gives the following as the mineral elements of this plant: PER ONE HUNDRED PARTS OF ASH. Silica 1.06 Potash 44.73 Soda 14.60 Lime 1.71 Magnesia 12.65 Phosphoric acid 17.64 Sulphuric acid 2.53 Chlorine 0.15 ----- 95.07 In this analysis neither the carbonic acid nor carbon were determined. It was further stated that the kernels yielded 2.08 per cent. of ash. These analyses, the one of the ash, and the other of the seed and husk in their natural state, are sufficiently full for the purpose in view, and serve admirably to show the principal elements required in the growth of the Peanut plant. We see that albuminous matter and starch form a very large per cent., over three-fourths, of the seed. Of course an article so rich in fat-forming ingredients, must be well suited for the food of man or beast. This explains why hogs fed on peanuts take on fat so readily. Nothing will change the appearance of a poor hog sooner than a diet of peanuts. The amount of oil in the seed--sixteen per cent., makes the Peanut one of the best oil-producing plants in the world. Of the mineral constituents, potash forms by far the largest part--44.73 per cent. Soda, magnesia, and phosphoric acid also enter quite largely into the composition of this plant. It will be noticed that common salt plays some part in the make-up of the Peanut.
