The facts that the horny gluten is per cent protein and that the germ is per cent oil, are very striking. The most significant table is here presented, which shows the percentage distribution of the chemical constituents among the physi- cal parts for an ear of medium protein content.

Germ. f. p. Floury part or white starch. h. p. Horny part, or horny starch. per cent of all the oil in a kernel of corn in the above case is in the germ. The fact that corn has a large or small germ is therefore indicative of its oil content. The large per cent () of protein in the horny starch accounts for the higher feeding value of well ma- tured corn, which always shows a greater development of horny Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly res
