Fm. sphplt., Foramen spheno-palatinum. Spheno-palatine foramen. 

 Fm. infor., Foramen infraorbitale. Infraorbital foramen. 



554. Lm. (Lamina) cribrosa Cribriform plate of the ethmoid. The mesethmoid 

 separates the bones of the two sides. The cribriform plate is the cranial part of the eth- 

 moid, the ethmo-turbinals properly belonging to the face. 



O. praesph., Os prassphenoideum, az. 

 Praesphenoid bone. 



O. pit., Os palatinum. Palate bone. 

 O. Ich., Os lachrymale. Lachrymal 

 one (Fig. 56). 

 O. planum (Fig. 56). 



O. ethtrb., Os ethmo-turbinale Eth- 

 mo-turbinal bone. In this figure is shown 

 the rounded scroll-like part projecting into 

 the frontal sinus ( 550). 



O. frontis. Frontal bone. 



Sinus frontalis. Frontal sinus (Fig. 56). 



555. Fig. 61 Preparation. 

 After the removal of the soft parts 

 (250, B), the rami were separated 

 at the symphysis menti (Fig. 62).

 LAMINA CRIBROSA AND THE SINUS 

 FRONTALIS : x 1.5. 



006. An. (Angulus) mandibularis. 

 Mandibular angle. 



Cd. mndb., Condylus mandibularis. 

 The condyla or arthral head of the mandible (Fig. 62). 



D. m., Dens molaris. Molar tooth. 



DD. pm., Dentes prsemolares Praemolar teeth. The bicuspides of Anthropotomy. 



D. c., Dens caninus. Canine 

 tooth. 



DD. i., Dentes incisores. 

 Incisor teeth. 



Fm. m , Foramen mentale 

 Mental or labial foramen. There 

 are almost invariably two on each 

 side in the cat. 



Fs. (Fossa) coronoidea Cor- 

 onoid fossa. From this fossa arises 

 a large part of the masseter muscle. 



Prc. cor., Processus coronoi- 

 deus. Coronoid process. 



557. Ramus, Ramus mandibularis Mandibular ramus. The mandible is made 

 up of two similar bones joined at the symphysis menti, and these rami form the frame- 

 work of the floor of the mouth ; Flower, A, 120. 



In Human Anatomy, the " ramus " is the so called " ascending part," and not the 

 entire half of the mandible as here ; Quain, A, I, 54.
