 lacerum basis cranii, another through anterior condyloid fo- 

 ramen to dura mater. Tempora'llS : from parotid gland up to 

 root zygoma, dividing into anterior and posterior. Trans-vet's a 

 facie'i, in parotid gland, runs across face, supplying glands, 

 integument and muscles, anas, with facial and infra-orbital. 

 Teuipora'lis me'dia, above zygoma to temporal muscle and 

 orbicularis, anas, with lachrymal and palpebral branches of 

 ophthalmic and deep temporal branches of internal maxil-

 forehead, supplying integument, muscles, etc., anas, with 

 frontal and supra-orbital. Te)npora f lisJ>oste'rior, up- and back- 

 wards over side of head, anas, with opposite fellow, posterior 

 auricular and occipital. Mazilla'rij intor'na I (see external caro-

 nosum, dividing into anterior and posterior branches, supply- 

 ing anterior and posterior surface of dura and bones, facial 

 nerves, and branches to other parts ] anas, with opposite fel- 

 low, anterior and posterior meningeal. Meninge'a fa^i-a, 

 through foramen ovale to Casserian ganglion and dura ; also 

 to nasal fossa and soft palate. Alveola'ris infe'rior, (inf. den- 

 tal) with dental nerve to foramen on ramus, then along dental
