MAMMALIA.

The inferior branch passes quite behind the angle of the lower jaw, and mounts up into 

 the face, along with the facial artery, just beyond the anterior insertion of the masseter 

 muscle ; it sends a branch forward along the lower jaw to communicate with branches 

 of the inferior dental nerve, to be distributed on the face and lower lip ; it then joins 

 the middle branch, where there is an intimate connection between this junction and 

 part of the buccal, passing towards the angle of the mouth ; it gives branches to the 

 muscles of the lips and mouth, and supplies the large muscles of the snout, as well as 

 the smaller ones connected with the skin of this part. In different animals, the several 

 branches are larger or smaller, according to the extent of the parts supplied ; the 

 ramifications of these also vary with the form and direction of the muscles. The 

 temporal branch in the baboon and monkey is small, also in the sheep, but in the calf 

 it is large, and still larger in the dog. There are differences also with respect to its 

 degree of communication with the branches of the fifth ; in the sheep, both pass nearly 

 separate to their destination : the final distribution of the branches arising from both is 

 not, however, in consequence much altered. The hard portion in the porpoise on 

 emerging from the cranium sends off slender branches at the lower part of the face ; 

 two pass down the neck to the cutaneous muscle, the other to muscular fibres on the 

 face ; it is then continued across the face and underneath the orbit, and sends filaments 

 to the muscle of the eye-lids, and to those at the angle of the mouth ; it then mounts 

 upwards somewhat like the inferior branch in the pig, and terminates on the muscles 

 connected with the blowing-hole. 



The glosso-pharyngeal nerve arises from the involuntary centre near the restiform 

 body ; it passes out of the head with the trunk of the par vagum. It then forms a 

 distinct ganglion in the dog ; in the goat and calf, it has a slight change in texture ; 

 but in the ass, sheep, and jaguar, it has not any discernible difference ; it, however, 

 varies in this respect in different instances of the same animal. It soon gives off the 

 tympanine nerve, which is usually large when compared with that in man ; it may be 

 seen ramifying in considerable branches on the external surface of the labyrinth, 

 particularly in the horse, calf, and sheep, and communicating there with branches of 

 the sympathetic, and the cord of the tympanum. It communicates with the superior
