In some places, as in the palm of the hand and foot, in the scrotum, tlie nipple of the breast, the scalp, Init especially in the axilla, this distal portion of the coiled tube is of \evy great length and breadth, and its epithelial cells contain a variable amount of granules. It appears to me that the cells resemble in this respect those of the serous salivary glands and the.
