Microscopic Examination of Red Currant Preserves.—Cells of theendocarp are the most conspicuous and characteristic elements ofcurrant preserves. Fragments of the epidermis and floral parts arealso evident, but are of less value in identification. The outer gela-tinous coat of the seed is destroyed by cooking, but the crystallayer and the inner epidermis retain their original form and may beidentified in surface mounts prepared by warming the seed in dilute jKmr- K lep.
