CHAPTER I. 
SUTURES AND BONES OF THE CRANIUM. 
Suture is made by the mutual indentation of one bone 
with another. Thofe which have proper names, are 
here deferibed; thofe which have not, derive their 
names from the bones they furround, and are known 
by them. 
Sutura coronalis (Tab. iii. iv.) runs acrofs the fcull, 
from one upper edge of the fphenoidal bone to the other, and joins the 
parietal bones to the frontal. 
Suturafagittalis(Tab. iii.iv.vi.vii.) joins the parietal bones: It begins 
at the os occipitis, and is continued to the os fronds, in children down to 
the nofe; the os fronds in them being two bones, and fometimes fo in 
adult bodies. 
Sutura lambdoidalis (Tab. v. vi. vii.) joins the back part of the offa breg- 
matis, or parietal bones, to the upper part of the occipital: In this future 
are frequently obferved fmall bones called olfa triquetra, and fometimes 
in other futures. 
Sutura fquamofa (Tab.iii.iv.v.vi.) is made by the upper part of the 
temporal and Iphenoidal bones, wrapping over the lower edges of the 
parietal bones. °
