This type of cell was said to differ from the ordinary- taste cell in that it was without a taste hair. It has not been identified with certainty by subsequent investigators. The supporting cells of the taste-buds have been the occasion of much difference of opinion. The older workers believed that these cells were limited to the exte- rior of the buds, but Merkel (1880) showed that they also occurred in the interior and Eanvier (1888) . definitely described both inner and outer supporting cells. Hermann (1889) concluded that these two classes of supporting cells differed not only in position but also in structure. The outer cells, which he called pier cells (PfeilerzeUen), were relatively large pyramidal elements whose nuclei were proximal in location and whose distal ends terminated in a zone marked with fine vertical stripings. For the inner supporting cells Hermann used Schwalbe's term of rod cells (Stabzellen) without, how- ever, wishing thereby to imply that they were of a sensory nature. They were said to differ from the pier cells in that they were devoid of the peripheral striped zone. Hermann also described basal supporting cells which to the number of two to four were found in the proximal part of the taste-buds. Von Lenhossek (1893b) doubted the existence of basal cells and described four not very sharply separate types of supporting cells. Graberg (1899) reidentified in human material the basal cells dis-.
