The thickness of this coat is about one-seventeenth of the diameter of the sac. The starch cells polarize light or not as they are uncooked or cooked. The cellulose envelope of the entire bean is made up of layers of crystal-like shapes, which are set in rows, their internal and external faces appearing very much like the tops of the Giant's Causeway crystals of traprock. These crystal-like elements of cellulose, when un-or partially cooked, are but slightly hourglass-shaped, but, when thoroughly cooked, appear like double-headed tacks. Epithelial cells and areolar tissue of beans may also be present. Bananas: --Clustered masses of starch grains. Cranberries: --Pigment cells of skins. Greens: --Spiral ducts in bundles, etc. Potatoes: --Cork cells, starch cells, areolar tissue. Gubernaculum tissues that lead from the eyes to the centre. The starch bundles or the starch in homogeneous masses, the pitted ducts, the vascular bundles, etc. Wheat: beard, outer coats, gluten cells, areolar tissue, etc., etc. This is only a very partial list of vegetable tissues. I have only indicated a few elements in order to show how to go at the study, for my own work has led me to distinguish many more forms. Saccharomyces cerevisiae. Sarcina ventriculi. Seroline. Several species of minute algae. Shreds of coagulated mucus. Sirocoleum. Strings of thin folded laminae of coagulated mucus. Strips of tissues, scourings. Sugar. Sulphuretted hydrogen vegetations. Tarry condition from bile which should have been carried out by urinary organs and sweat glands (Salisbury). Tegument of wheat, cigar coat. Tough ropy mucus (colloid). Tripl
