Index of the Second Figure and Its Characters

L Here a small portion of the frontal bone is visible.
O, O, P, P The cuneiform bone.
Q, G The previous figure also has this bone, marked G; it is the first bone [os zygomaticum] of the upper maxilla. 20
S, L The previous figure marks this bone L as well; it is the fourth bone [maxilla] of the maxilla.
V, X The part of the skull which anatomists call the jugal bone [arcus zygomaticus] has already been explained. 21
Y Suture [sutura temporozygomatica] joining the two processes which form the jugal bone.
d Here the suture [s. sphenozygomatica] separating 22 the first bone of the upper maxilla from the cuneiform is hidden; also a portion of the suture [s. zygomatica] separating the first maxillary bone from the fourth, visible in the hollow of the temple.
e Suture [sutura sphenomaxillaris] common to the fourth maxillary bone and the cuneiform. 23
f A portion of the suture separating the first maxillary bone from the fourth, appearing in the anterior region of the maxilla and marked in the previous figure from a to b.
g Suture [sutura frontozygomatica] common to the frontal bone and the first maxillary, which we marked R in the preceding figure.
P Sixth bone of the upper maxilla [lamina horizontalis ossis palatinae].
q The suture [s. sphenopalatina] common to the sixth bone of the maxilla and the cuneiform is marked from e to q.
S [facing backward] The nasal septum [vomer], and the point where it is separated from the cuneiform bone.
t, u The transverse suture [sutura palatomaxillaris] separating the sixth bone of the maxilla from the fourth is marked from t to u.
x The suture [sutura palatina mediana] dividing the two sixth bones of the upper maxilla from each other, and common to those two bones, is marked from x to t.
y The suture [sutura palatina mediana] running straight through the palate, common to the fourth bones of the maxilla.
z This specifically marks the foramen [foramen incisivum] appearing in the front of the palate, in the region behind the incisor teeth;
a near its side an obscure suture [sutura incisiva] sometimes occurs, running transversely to some point in the fourth bone of the upper maxilla. This is marked a.
