The : ^-3^' basal half of many of the bulbs rests entirely in the mucosa, and is fre- quently bent somewhat downwards. Non-medullated nerves approach the furrow from the sides, and their terminal branches can be followed directly to the bases of the bulbs. The organ bears a striking resemblance to the duct of a gland, and doubtless represents the papilla foliata in its simplest form. Amherst, Mass., 11. May ^ l^. Nachdruck verboten. The epitrichial Layer of the hnman Epidermis. By John T. Bowen, M. D., Boston, U. S. From the histological Laboratory of the Harvard Medical School. With 5 figures. The investigations, of which this paper offers a brief outline, were begun in October 1887, and have been prosecuted, with few interruptions up to the present time. The subject was brought to my notice by Dr. Charles Sedgwick Minot, with whose kind aid these studies were undertaken, and to whom I am indebted for many valuable suggestions. Dr. Minot had observed in bits of human foetal epidermis, when separated from the corium, stained, and examined with the outer surface uppermost, an outer layer of large polygonal cells, with well marked outlines, and in their center a granular deeply stained body, within which a nucleus could usually be seen. These granular bodies he considered to be the shrunken cell protoplasma,. Please note that these images are extracted from scanned page images that may have been digitall
