The P: A MA T E R is a fine, delicate, double Memb rane which lies under the Dam Mater, and immediatel y covers the Subiiance of the Brain. Its inner Membrane is much larger than its out~ ward, for it runs in betwixt all the Foldings and Circumvolue- tions of the Brain, to feparate them, and to fullai n the BloodVeiTel s. The BR AIN is the whole Mafs contained withi n the Bones of the Skull. It is divided into the Brain properly (2) called , the Carri‘tl/zrm and the [Vida/[(1 Oblongm‘a ; to which may be joined the fpinal Marrow contained in the Canal formed by the Vertrdrce. ' The Brain properly fo called, is compoied of two Subfiances; the firft is the external, which is of an afhy Colour, and the internal which is ofa white Colour; the latter is called the Sub/22am tz'a {Veda or ORGANICAL PARTS. . . 7 . . _ The Arteries are not accompanied With ihegV (fins, as :lnfgillezt " eniei ‘ttheilcu mama} b" a 16 : h ya Parts ofthe Body ,- they_ ' botn rner ' 1. t, mg Blood they ) 1 , er'd toeether b becaufe 'if they enteic ‘ Way, . eu‘ I), . ‘ r M ot tiic c to the Courie Com refiion, create an Ob {lacle Sm licaring, Sight, or Organs the of Tiie FAG E is the Seat . _ 1 Ma ' ' ' itication. and Tafiino S eaking, mgThere aritviio Kind of Parts Which form the Organ: q/‘Ségljf, the one are external to the Globe of the Lye, andhthelorher? 011;]: 7 (.1, 7' 3C8 , furt I"e t t iyVH1!) ‘ , ' a re the Eyebrows, ‘ ' Globe.
