Glutenins and Starchy Corn. — The germ and aleurone layers are more nitrogenous in character than the interior or floury portion of the kernel. Since the proportion or germ and aleurone in corn, as in wheat, varies with individual samples, the nitrogenous matter, being greater in these parts, also varies. Taking advantage of this knowledge, it is possible, by mechanical means, to distinguish corn samples of high from those of low proteid content.

" By making cross sections and longitudinal sections of several kernels from an ear of corn, one can judge, with a very satisfactory degree of accuracy, whether the corn is rich or poor in protein. The illustration Fig. 90. — Nitrogenous and non-nitrogenous (Fig. 00) here shown was corn: r> <rorn with I4-92 per cent proteln; • ° r 2, corn with per cent protein. made from a photograph taken of the corn kernels and sections with a magnification of three diameters. At the left are two sections and a whole kernel from corn containing per cent of protein. The sections and kernel at the right are from corn containing per cent of protein. About one fourth of the kernel was cut off from the tip end in making the cross sections. In the longitudinal sections the tip end of the kernel points upward to the right. It will be seen that in the.
