Fm. sphplt., Foramen spheno-palatinum. — Sphenopalatine foramen. 

 Fm. infor., Foramen infraorbitale. — lut'raorbital foramen. 



§ 554. Lm. (Lamina) cribrosa — Cribriform plate of the ethmoi(i.--The mesethmoid

O. preesph., Os praesphenoideum, az. — 

 Prffispheuoid 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).

§ 555. Fig. 61— Preparation.— 

 After the removal of the soft parts

 at the symphysis ment'i (Fig. G2).

Pre. cor., Processus coronoi- 

 deus. — Coronoid process. 



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