Abstract
THE very interesting nerve connexions of the taste-buds in the pig do not appear to have attracted attention. In this animal the taste-buds are almost entirely concentrated in the circumvallate papillæ, of which there is but one on each side. This is quite a large structure, about 0.5 cm. across, and contains about five hundred buds. In its base is a large ganglion containing nerve cells of two different types and obviously connected with the buds and the nearby glands of von Ebner which irrigate the vallum of the papilla. The nerve from this ganglion contains about three hundred and fifty fibres and constitutes rather more than half the total number of fibres making up the glossopharyngeal as it crosses the hyoid. The degenerative changes resulting when the nerve is cut at this level show that the fibres are the axons of the ganglion cells.
