which occupy corresponding recesses in the ordinary epithelium; each presents a 
minute opening, the gustatory pore. The buds consist of fusiform supporting cells 
grouped around central gustatory cells. The latter are long and narrow; the 
peripheral end of each bears a small filament, the gustatory hair, which projects at 
the gustatory pore; the central end is produced to form a fine process which is often 
branched. The taste buds are innervated by fibers of the glosso-pharyngeal nerve 
and the lingual branch of the trigeminus.

The eyelids are thick, prominent, and less pliable than those of the horse. 
The lower lid bears a considerable number of cilia, which are, however, finer than 
those of the upper lid. The tarsal 
glands are more deeply embedded 
— 9 and therefore not so evident. The 
conjunctiva of the lower lid presents 
folds or ridges, and one or two promi- 
nences which contain numerous leuko- 
cytes; the conjunctival epithelium is 
transitional in type. The superficial 
part of the cartilage of the third eye- 
lid is leaf or shovel-shaped and thicker 
than in the horse; the edge bears a 
narrower process, on which there is a 
transverse bar, giving the arrange- 
ment some resemblance to an anchor. 
The gland of the third eyelid is very 
large—an inch or more in length—
