evenly with small, fine, soft conical papille directed backwards. 
Amongst them a few round fungiform papillz are scattered; but 
these become much more conspicuous on the intermolar eminence. 
There is no sublingua. 
The salivary glands are very largely developed. 
The parotid is exceedingly large and of very loose texture, its 
very numerous lobules being very much scattered and in part loosely 
coherent. It is arranged in two superimposed layers in folds of 
gland-substance, and extends over the whole side of the neck, 
where it forms a large mass dipping into a triangular cavity above 
the cleido-mastoid muscle, between it and the levator clavicule, 
and even a little beyond the clavicle. Its anterior margin is 
strongly concave forwards, extending almost as far anteriorly

beneath the mandibular angle as it does in front of the opening of 
the external auditory meatus. Its duct runs forwards across the 
masseter muscle, just below and parallel with the Jower border of 
the zygoma, to open beside the anterior molar tooth. 
The submacillary is large and of very similar texture to, but only 
between 3 and 2 the size of the parotid. It is pyriform in shape, 
lying beside the inner border of the masseter, and separated from its 
fellow of the opposite side by the sternohyoid muscles. Its duct 
runs forwards along the inferior margin of the masseter muscle to 
end as usual, The length of the submaxillary is about 2!'°4, its 
breadth about 1-5. The gland is almost divisible into two parts,
