The caufes of an Inflammation of the Coats of the Brain, S to the Pathology of the Brain as affected with Inflammations, Ab. fee-fies, Ulcers, an Epileplie, and Pains. The inflammation of the Membranes of the Brain is caufed by Ragna. A llrong Putgativc not good iiian luflammation of the Heath God's mercy, he molt happily exchanged his lower Ration, for a better above. And in a decent time after his departure, I ordered an expert Chyns rurgeon to take off his Scalpe and Skull, where I found underneath, all things anfwer our expectation, and out of the third Sinus, immediately guflied out aRivulet of Blood, and all the Capillary Arteries (which are f0 fmall nan turally, that they can be hardly dilcerned) were here very large and confpi~ cuous in the Dun: and "Pia h'latei', which were molt prodigioufly fwelled and inflamed to the admiration of the Beholders, the Blood being fetled in the Spaces between the Veflels, in lo great a plenty, that the Veins were not able to difcharge it. And the Siam were furcharged with fo much Blood, that the Jugulars tion of Blood, impelled by a violent ptilfation of the internal Carrotide Arteries, into the fubfiance of the Coats, in lo large a proportion, that the mi. nute Extremities of the capillary internal jugulars, are not capable to receive it, whence arife greater or lelis tumors of the Membranes by the undue de- below, were not in a capacity to employ them: Whence is derived an In‘ flammation of the Coats of the Brain above, the courfe of the Blood being tention of more or lefs Blood, fiagnant in the Interlhces of the Veffels. And lofe its Tone, and its Compage growing loofe, the Criltallinek part doth fe- furthermore, the fevetal Sinws of the Brain are then overcharged with fo great quantities of Vital Liquor, when the more minute Chanels of the 111gulars below are not fuflicient to admit the great plenty of Blood tranfmit- parate from the Red Crafiament, and turning corrupt, dorh degenerate intoa Purulent Matter, the immediate fubject of an Abfcefs, which being affected witha kind of Cauiiick quality, corrodeth loinetimes the flura, and other times the 'Pia Mater, which being Perforated, determineth in Ulcers, ted to them ', Of which be pleafed to take this inl'tance. An inflame of an Inflammation of the Coats of the Brain. Of the ‘Pdt/M/ogj of the Mcmbrzmer of the grain. A Gentleman of Oyality of a Plethorick confiitution in the flower of his age, taking too great afreedom in the larger draughts of ill Wine, fell into a dangerous continued Fever, accompanied with a fierce Eryfipelm, figmficd in prodigious Tumors full of Blifiers and Pimples in the Neck and Face, and the Eye-lids f0 tumified, that he was wholly blind, and in this extreniity he fent for a Chyrnif‘t, as I conceive, a better Operator then Phyliciari, more skilled in the preparing then due adminif'tration of Medicines, who g1veth him a Purgative in the hight of his Difeafc, which worked freely with him,aud flrangly difcompofing him, brought him a great Stupor,upon which he was deprived of Senfe and Speech a final] time after the working 0f the Purgative, Nature labouring under a double violence of a Medicme and at Difeafe; whereupon his Friends fent to me to vifit the Patient, defperately lick, and finding by their obfervarion, that the fwelling of his Face and Neck liiddenly fell, with the lols of his Senfe and Speech upon the plentlfill operation of the Medicine, I had reafou to believe, that the Blood before intercepted in the Veins below, they being not fufiicient to reconvey it out: of the fubfiance of the Membranes 3 whence the Blood flagriating, doth affecting the Cortex and fubfl'ance of the Brain, accompanied With a Stupnr andSopor, the fore-runners of a fatal Apoplex. And farther, It may be conceived, and not altogether without ‘reafon, thatthe Coats of the Brain are the fubjeét of the Epilepfv, as they are the Organs of Senfe and Motion, and as they are endued with a great number of Nervous Fibres, with which the molt part of the fubl'tance of the Membranesof the Brain is compelled, and are difperfed all over it; And thefe Coats do not only invef't the Brain, but infinuate themfelves into the in-‘ ward Recelles and Fiffures of it and the Cerebellum : whereupon the Animal Liquor being infe&ed with Nitra-Sulphureous and other malignant Particles, falling into the numerous Fibres of the Membranes of the Brain, do highly irritate thofe tender Senlitive Filaments. putting themfelves upon various inordinate and convulfive motions, in order to difcharge the noifome Epilep» tick Matter, that (o greatly ofl‘endeth them ; and the Membranes not only invelling the Cortex, but alfo the Medullary Proceffes, being highly con- fiaguant in the Face and Neck moving from the Circumference to the Cen- tl‘fiélCd do comprefs the Brain, and hinder the entercourfe of the Animal ter, had a fpeedy rccourfe from the ambient parts by the external Jugulm into the defceiidcnt Trunk ol‘thc Cam, and was thence tranfmitted through the right Ventricle and Lunqs, into the left Ventricle of the Heart, andfrom thence imported by the afcendent Trunk of the Aorta, and internal CaIO' tide Arteries, into the hiembranes andfubi'tance of the Brain, in {0 great 3 quantity, that it intercepted, by comprefling the Fibres of the Brain; ‘hc Liquor and Spirits, difiurbing the fenfitive and nobler Intellectual Operations 5 and do alfo, being hurried with violent concuflions, draw the appen~ dant Nerves into confent, affecting them and the Mufcular parts with molt fierce and Convulfive Motions, mofi terrible to behold. . The Cephalalgid or Pain of the Head is feated principally, if not wholly Thedefcrlpc 1n the Burn and (Pia Jvfenynx, and may be ( as I conceive) defined a trou- {155253; blefome fenfation of the numerous minute Fibres integrating the Membranes "‘34Oftbe Brain, flowing from the folution of the Continuity -, And according to the greater or lefs extent, is called Univerfal or Particular ; Univerfal when all Parts Of the Membranes are affected, and Particular, called Hemitram'a, influx of the Animal Spirits into the Nerves, the infiruments of anlca MC? tion, 311d Language, proceeding from the l'taguation of Blood, whence 3110 arofe a great rednefs and tumor of the Membranes of the Brain, whereUPQ" I immediately ordered, (the Neck being fwelled) a Vein to be open€d l" the Arm. a large Orifice to be made, for the freer emiflion of gl'Ol-S BIOOdt to quicken its motion from the Head towards the Heart, and fome hours 3' ter, I repeated the Blood-letting, and ordered Cupping-Glades to be 313‘ plied with deep fcarifyings, but all in rain, as being not able telievethCPi' tient with Bleeding, and the bell Cephalick Medicines both inwardly take" And in the Cephalalgia, Ithall give you a fhort Hillary of the parts affectEd, the Effence, Catifes, and Differences.
