/'//./. initial nerve. When the branch constituting the superji--i<il t< m/Ktral nerve 

 reaches the jxisterior bonier of the maxilla, it divides into several ramnscules; one 

 lotion lies beside the middle branch of the facial, the other accompanies the anterior 

 auricular nerve by becoming intimately united to it. We have also found, in the Dog, a 

 branch that is detached from the inferior maxillary, almost immediately after its exit 

 from the cianium : it descends into the intermaxillary space, in company with the facial 

 artery ; at the posterior border of the mylo-hyoideus muscle it separates into two 

 lainiiscnles : one is applied to that muscle, and follows it to near the symphysis of the 

 jaw ; the other is inflected outwards and upwards, in front of the masseter muscle, and 

 joins the inferior branch of the facial. Owing to this arrangement, each of the branches 

 of the facial is provided with a sensitive ramuscule from the fifth pair. 



Fticial. At its exit from the external auditory hiatus, it divides into four branches, 

 three of which api>ear to form its termination. The first, the smallest, is directed down- 

 wards across the parotid gland, and constitutes the cervical ramuscule. The other three 

 are distinguished as superior, middle, and inferior. 



The superior brunch, the largest, ascends towards the forehead, and describes a curve 

 whose convexity is upwards, turns round the orbit, and terminates near its nasal angle. 

 In its course it furnishes: 1, An anterior auricular ramuscule; 2, Above the insertion of 

 the masseter, several museul-T filaments ; :-?, It is crossed, above the eye, by the super- 

 ciliary filaments of the ophthalmic nerve. The middle branch accompanies 8 tenon's duct 

 to the surface of the cheek ; reaching the anterior border of the masseter, it anastomoses in 

 a very tlexnoiis manner with the minuscule of the inferior branch, and terminates in the 

 upper lip and the end of the nose The inferior brunch passes towards the maxillary
