Part II, folid parts of the Body are rendted Cations: And farther it may be urged, Sympathy betWeen the Teeth and Ears, whence it hath been obferved that their Figme as an argument of their Solidity and Hardnefs, that they retein the Teeth have been offended by fome great Sound. And if anv Petfon {hall have fo little Faith, as not to believe the entrance of the Vellels inro tl e Boots of the Teeth, the hole into their Mucous parts will confirm it where the Capillary Arteries may be difcoveted to enter into that l the Membrane invcfting the inward Cavity of the Teeth, hath been Renato be Bloody, and that the Nerves do infinuate themfelves through the fub" {lance of the Teeth into their inward liecelles, their acute Senfe will con~ Attrition, for the Comminution of hard and lohd Bodies in pomt of Non. rilhment. . The Teeth are accommodated with divers forts of Veflcls, Arteries, 5",:Iflfl't‘fll Veins, and Nerves: That they have Arteries, is molt evident in thofe that are afllifted with fevere pain in the Teeth, wherein they perceive a huzh hearing, proceeding from the troublefome Pulfation of the Artery. And Perfons who have their Teeth drawn out by Violence, are obnoxrous to great fluxes of Blood, caufed principally by the Laccration of Arteries inferred into the Teeth. fPldlcrln malceth mention of the Drawing a Tooth, that proved fatal Thedrauiiig }'Eq‘f{,‘,l,'c‘,‘,c_ to the Patient, who laboured with f0 great a Flux of Blood grilling affirm; out of the Cavityof the Mandible (upon the Laceratlon or an Artery) Urmorrhdsm that no Art could lupprefs it. The Arteries importing Vital Liquor into the Teeth, are yn'opagared from the Anterior and Polierior Branches of the external Carotides; of which, two enter under the Ear into the lower Mandible, and are infer-'5 i into the Roots of all the lower Teeth, and by thefe Veflels lharp Humour; ;lii>ciated with Blood, do enter into the Cavity of the Teeth, and afflict the Mim_ branes (encircling outwardly the Roots, and inwardly the Marrow of the £13133:- Tecth) conlifting of many Nervous Fibrils, endued with molt acute $933,," Senfe; whence arife thofe feverc pains of the Teeth, wherein the Mem- ‘,‘;‘£‘,‘]‘_i"8"‘" bi'aneis vellicated with the Saline Particles of ferous Humours ( confederates of the Blood) carried into the Coat, invelting the inward Cavrty 0f the Teeth, by the external Carotides palling under the Eat. VVhereIJpon to prevent the Pain of the Teeth, lodged in the lower Mandible, Afiringent Medicines may be properly applied under the Eats, to hinder the recoutlc 0 Humours into the lower Mandible. A . ilihiiriifliiich The Anterior Branch of the external Carotide Artery, doth allo immit exit-marche- many Capillaries, into the upper Mandible, and Teeth feared in it, and "‘"Amms' the external Carotides do infinuate many Ramulets into the Roots of the Teeth through minute Perforations, which may be feen in the 10iver Region of the Teeth of Infants, when they are foft and Mucous, but cannot be difcovered in the Teeth of Petfons of more Mature Age, in whom though the entrance of the Arteries cannot be made good by Autopfy, yet itmay be proved by Reafon and Experience ( who are great Mallets in Art) by {53' ion of the great Hemorrhages, that proceed from the Laceration of Arteries, upon pulling out of Teeth, which hath been more frilly difcourfcd above. Swami? Teeth are not only furnifhed with Arteries, derived from the exterm . \wvllu- Carotidcs, but with Veins alfo derived from the Jugulars, which are divided . ' V into \ince us: Whereupon, if one of the Grinding Teeth hath :1 Perform tion by forne Corroding Matter, into which a Needle may be immittetl a troublefomc Senfittion will follow, which cometh from prickins' the Membrane, lodged in the Penetrals of the Teeth: And thounh the l'ln lTnl'IrIElOI‘l of the Velfels cannot be difcerned in the Teeth of Mei; of riprr Years, yet it is very vilible in Bruits, whofe lower Mandible being opened in the inlide of the Cavity containing the Marrow, the Artery, Vein and Nerves, do offer themfelvcs to our view, as loving Allociates, encircled with one common Membrane,which being opened,a Nerve appearetha'onmo» fed of many Fibres, between which, divers Branches of Arteries and Vein; are lodged, and the Membrane being lifted up, many Fibrils may be dill: cerned, which refemble a Spiders Web, and tend to the Roots of the Teeth and if any of the Teeth be taken out of its Cavity, we may fee thole lVli: nute Fibrils conjoined to the Roots of the Teeth. ' .The Teeth, in reference to their Connexion, are enclofed about their middle Region in the Gooms, as within foft Repofitories, and their Roots lz' Hmliom are lodged within the Cells of the Mandibles, as within more llrong Walls . 5133:?" 5'; and when thefe parts are immured above with a more tender and bClO"; "ml": l. with a more hard Confinement, they are covered with a more, thin Mem- brane, as with a fofter Vail. The Teeth borrow their Origen, with all other parts, out of the Genital Matter, and have their firfi Rudiment in the "term ; where they lie obfeure= ly within the Cavities of the Goomes and Mandibles, as in fafe Allodga merits, in which liep by ftep, they arrive unto greater and greater Matu~ rity: And upon the opening the Goomes and Mandibles of Abortiv‘es, a treble printiple of the Teeth may be difcovered, confiliing of a Membranous, Olleous, and Mucous part. The firll is a Membrane, as a Cafe encircling the Bony and Mucous parts and refeinbleth a Cortex, encompalling the Medullary Matter of the Seed: and 15 not Wholly Membranous, but fomewhat Mucous, having Perforatin N f » ons above and below, out of which the Teeth do fprout in their firfl: more i‘ii‘gli‘l‘ix rough, and imperfect Delineations, made up of a Bony and Mucous Mat- foils" MW 181' 5 the Olleous part is the bafe of the Teeth, and beginneth after the manner of a Shell, and by degrees is Confolidated into a. firm white fubll'anCC, Iii and it and Mignitudc, although they have been manyh'ears expoled .to frequent Ellis into two, the lix'erior, and Interior Branches: The firll: tranlinitteth Ca, pillaries into Teeth of the upper Mandible, and the Exterior into thofe of the lower Jaw.
