Chap. VI. The Anatomy of a HOKS^. 79 



ThQCoronal^ fo called becaufe the Ancients were wont to 

 wear their Crowns or Garlands on that Part. The Suture, 

 ?s in Men, fo likewife in a Horfe, runs athwart the Skull, 

 above the Forehead, reaching on each Side to the Temple- 

 bones, ar.d joining the Forehead-bone to the Sinciput. 



The fecond, LambdoideSi becaufe of its Refemblance to 

 the Greek Letter A. This is feated on the hind Part of the 

 Head, being oppofite to the other, beginning at the Bot- 

 tom of the Occiput^ and defcending above the Ear fome- 

 vvhat higher than in Men. It joins the Bone of the Occi^ 

 put^ or hind and under Part of the Skull, to the Bones of 

 the Sinciput and Temples. 



The third begins at the Middle of the Lamhdoidal Su- 

 ture, dividing the two Bones of the Sinciput^ and is there- 

 fore called the Sagittal Suture ; but in Horfes, and many 

 other Quadrupeds, it crollcs the Coronal Suture, as in Chil- 

 dren, quite down to the Nofe. This Suture in a Horfe 

 is not fo much indent as the other two, but is in a great 

 Meafure ftreight and linear. ' 



The falfe Sutures are in Number two ; Its falfe Su- 

 the firlt palles from the Root of the Pro- . ^"f"^^- 

 cejjlis Mammillaris with a circular Dudl, returning down 

 again towards the Ear, encompafling the Temple-bone. 



The fecond runs obliquely downwards, arifing from the 

 Top of the former, and palles to the Socket of the Eye, 

 and the Beginning of the firft common Suture. 



Thefc Sutures, which are common to the *^ko/e common 

 Skull, the Wedge-like Bone, and upper Jaw, ^-^ ^^-"^ Skull and 

 are chiefly thefe three that follow, to wir, «//^^ 7«w. 

 the Frontal^ the JVedge-Uhe Suture, and the Cribrofa : 

 The firft being that by which the Procefs of the Forehead- 

 bone is join'd with the nrll Bone of the upper Jaw ; the 

 fecond that by which the Wedge-like Bone is join'd with 

 the firft Bone 'of the fame Jaw ; and the third that Suture 

 which is common to the Wedge-like Bone and the Septum^ 

 cr Partition of the Nofe. 



The Sutures are of Ufe, not only as they ^heirU/e. 

 divide the Bones which compofe the Skull, 

 buialfo as they afford a free Ingrefs and Egrefs for the Veflels 

 which fupply Life and Nourifliment to the Parts contained 

 •within the Skull, and likewife as they give a Pailage to thofe 

 little Fibres, by v/hich the Dura Mater is kept fufpended : 

 And further, they are of Ufe in Cafe the Skull ihould at any
