Here the buds open into the ditch between the ridge on which they are located and the next one. In sections transverse to the axis of the ridge the numbers of taste-buds seen on the two sides of a given ditch may vary from three to twenty. In the rabbit the foliate pa- pilla are especially well developed and are abundantly supplied with taste-buds. These have been very fully studied recently by Heidenhain (1914) who has shown that the buds are arranged in more or less vertical rows on each papillar fold and that they probably increase in numbers by a process of fission. The vallate papillae, which in man are usually six to twelve in number, form on the posterior part of the.
