The wounds of the Skull, as being an Integriment of the moil: noble part Book III. c H A P. XXXi. 0f the Dam Zléfcnjnx6 of the whole Body, do threaten great danger, as often affefting the MemA rmaIlFifi branes and fubfiance of the Brain. The danger is lefs when one Table is wounded, and greater when both gliiifisiiiy are divided, and when the Filfure is fmall it hath molt of danger, and H, d"‘""°"5' in a Seder when the wound is broad and not deep, without any Contufion rnwoumor or Figure, which when made through both the Laminfl, is attended with a iaéiildiiiii. Flux of Blood ( coming from the lacerated velfels) falling down upon the Dltrd Mater, often productive of an Apoplexy, from comprefliug the Origens of the Nerves, and intercepting the Influx of animal Liquor. The fracture of the inward Table is fometimes accompanied with fhivers of the Skull, which do prick the Coats of the Brain, and produce dreadful fymptomes, which prove very fatal, efpecially if the fragments of the broken Skull do penetrate the fubi'tance of the Brain. In hidden Fractures and Contulions, the Mcditullium is often wounded, and its veffels broken 3 whereupOn it is filled with extravafared Blood, which putrifies and corrupts the Skull. Wounds are dangerous in the Sutures, in reference to the weaknefs ofthe Skull, and by reafon fome part of the Dura Mater is fal'tned by Fibrils to the n‘ Y [nterPcices of the Sutures. _ (- Deprcflions of the Skull are not fafe, becaufe there is but a little fpace bedrpnmmtgft tween the Skull and the Brain , whereupon it being compreffed, is often en- ntsnm. gaged in ill accidents, which are of Two kinds, which follow the affeétions ol the fubfiance of the Brain, and its neighbouring parts, as a. Convulfio n, Palfy, Sopor, Stupor, Delirium, and a Fever. A Second kind of Symptomes is lefs terrible, and follows the commotio n of the animal Liquor and Spirits, whence Patients are deprived of their Speech, Hearing, and Sight, which often return without any great prejuice. dink]??? : Accidents coming in the beginning of wounds of the Head, as pain ofthe 33,}. 5" ' ‘ Head, and bleeding of the Nofe, or the diflurba nce of the animal Spirits are not deadly; and ill fympromes arifmg about the Rate of the Difeafe are worfe, by rcafon they denote a collection of rPu: or fanious And if a Fever doth appear about the Fourth or Seventh day, Matter, (Wit proceedcth from the generation of 'Fur, and if the Fever happens after that time, it may have a more fad con-fequence, as denoting the corruption of the coats or lubllance of the Brain.

And afterward I intend to give you alfo a Hil'tory of the progrefs of the Animal Liquor, how it afsoeiateth with the Chyle, exalting it in its {Everal local and incel'rine motions through the Ventricle, Guts, Mefentery, and thoracick Duels, and how the Animal Liquor curring into an intimate Confederacy with the Blood,enobleth it in its Circuit through the Kidneys,Spleen, Liver, and the Chambers of the Heart, and pafsage through the Lungs; as alfo through the common and afcendent Trunk of the Aorta, which lead into the Carotide Arteries, climbing up into the highell fiery; w here my purpofe at this time is to give you a defcription of the fine Veilments, and rich Houlholdfiulf of this molt excellent Aparriment, and the Origen, Sub- fiance, lifts, and action of the Coats, Cortex and elegant Procefses of the Brain, and where, how, and of what the Animal Liquor is generated, and propagated through the feveral Proceffes of the Brain, into the Nerves, as fo many elongations, and outlets of it, made for the exercrfe of the rational fenfitive and motive Powers and Funé'tions; and what proportion or dilproportion the Coats and Procefses of more petfeét or imperfect Animals hold . with that more noble Fabrick of Humane Brain.
