PLATE XLIII. 

 THE FACE. 



This dissection shows as far as possible the structures of the face ; no attempt was 

 made to dissect out the small muscles of the nose, but the rest of the structures are well 

 shown. The accompanying diagram shows the cutaneous nerves of the head and neck. 

 (A) supra-clavicular 

 (3 + 4 C) ; (B) super- 

 ficialis colli (2 + 30); 

 (c) great auricular 

 (2 + 8C); (D) small oc- 

 cipital (2 C); (E) great 

 occipital (posterior 

 division of 2 + 8 C) ; 

 (F) auriculo-temponil 

 (3rd division of 5th) ; 

 (o) temporal twig of 

 temporo-malar ('2nd 

 division of 5th) ; (H) 

 supra-orbital ; (i) la- 

 chrymal ; (K) frontal ; 

 (L) twigs from infra- 

 trochlear loop (all from 

 1st division of .1th i ; 

 (M) infra-orbital (2nd 

 division of 5th) ; 

 (N) malar branch of 

 temporo-malar (2nd di- 

 vision of nth) ; (o) nasal 

 nt Tve (1st division of 

 5th); (P) mental branch 

 of inferior dental (3rd 

 division of 5th). 



There was no divi- 

 sion of the zygomatic 

 muscle into major and 

 minor ; in fact the 

 latter is but a slip of 

 the major which has 

 remained separate 

 from its anterior edge. 

 Nor is there any sepa- 

 ration, as a rule, 

 between the adjacent 

 edges of the leva-tor 

 labii superioris and the 

 leyator labii superioris 

 alaeque nasi, and but 

 a faint attempt at divi- 

 sion ; in fact the whole 

 should be called the 

 levator labii superioris, some of whose inner fibres get an insertion into the alae of 

 the nose. In the chimpanzee these four muscles, the two zygomatici and the two 

 leva tors, are united to form one broad muscle which arises round the circumference of 

 the orbit and runs down to be inserted into the upper lip.
