Marked features of the soy bean arethe high column cells of the spermo-derm, the presence of an endospermand the absence of starch in the coty-ledons. The Spermoderm (Fig. iqc)) is closelyunited with the layers of the endo-spcmi. 1. The Palisade Cells (pal) of tliisseed are of about the same height(50-60 /<) and diameter (6-15 /() asthose of the common bean and, likethe latter, may or may not have colored contents, according to the colorof the seed. liiiiii.

The hour-glass or I-shaped cells are usually 35-50 ri high,but about the hilum they often reach 150 u. In width they vary from16-36 fi. Since the cells have a marked tendency to separate from theadjoining layers and from each other, isolated cells may usually be foundin considerable numbers in surface mounts obtained by scraping the innersurface of the hull, or
