Some PUTS"! I'tfllim and Velmrdzz, two renowned Anatomifts, report that fome Perilfffi‘l‘fil,‘by fons, by the interpofition of this Membrane, have been able at their plea‘Cm‘mcw fine to move their Skin both in Back and Breal't, which in them was a great Fégiifiic variety of Nature; not recounted by any other Authors, as far as [can learn. Axiptfz. And this unufual motion of Back and Breal't, was aceomplilhcd (as I conceive) by Catnous Fibres inferred into the Memlvrmm Adipofa, by reafon this :iéiion was celebrated by a thin Mufcular Expanfion, here the immediate 1113.chin of voluntary motion. Iii/mm. This Membrane in Bruits, is a thin Cutaneous Mufcle, immediately furL151??? rounded with the Skin, which celebrating various concullive motions, by §?:§§.,.ir."oi{i"2§ frisking up and down the Skin, giveth a difiurbance to the importunare guefis Mumc. of Flies, and frceth it from other ill accidents, which difcompofc their cafe and quiet. This Mufcular Expanfion of other Animals, in whofc diffeftion molt Anatomifis have been commonly exercifed, hath given ocCafion to deceive them, thereby giving their opinion, that this Membrane was alfo Carnous in a HHmane Body, which is found only in its Neck and Face, and other parts are difcerned to be Membranous. Therefore in a Humane Body, it may truly obtain the appellative of MEI/1' b74714 Adipflfd, becaufe in molt parts it is of a membranous nature, being 3 inc "W! in. Chap.

It feemeth to be a great fecret in Nature, how Fat is generated, whofe Heat cannot chirient caufe is configned by many Anatomifls (of no mean Rank) to "mm the firli qualities of Heat and Cold. As to the firft, It can hardly be com mired, how it lhould be produélive of Fat, which Iguefs proceedeth from Sulphureous parts concreted, no Ways to be el'feéled by Heat, rendring them fluid, which is effeéted by a Colliquating power: And all unfluous bodies which are rather condenfed by Cold, are rarefied, and melted by hot Par: titles. So that Cold rather, or at Ical't a very gentle Heat (which is a kind of COMM" comparative Cold in reference to a more intenfe Heat ) doth contribute iiiircliiogh. fomcthing to the concretion of Fat, made of Oily Particles. fecerned from the WWW Satan hutririm (allociated with the Blood) in the fubftance of many Glands (befetting the Membraim Adz'pofiz) and thence conveyed to the empty fpaces of the Veflels, to whofc lides the unéiuous parts of Fat do adhere. Whereupon Ido humbly conceive, that Fat being attenuated by heat, and condenfed by cold, is only altered by them according to different modes of the Matter, as being rendred fluid or condenfed; which are no ways the intrinfick caufes of Fat, formed out of the 9ulphureous parts of the Suctm Nurricim, which are liquid, as long as they move in company with the Chyme and Vital Liquor in the Veflbls; out of whofe Tcrminations they are tranfmitted into the fubflance of many {mall Glands, as f0 many fifainers of the oily Juice , which afterward exudeth into the habit of the Body, Where it being defpoiled of motion in Extravafation, gaineth a more folid fubr'iance, and there being concreted, is affixed to the Walls of the Veflels. And oftentimes concreted Matter doth reaffirme its primitive nature of a Wm the liquor, when colliquated by unnatural heat, or extraordinary motion ; and film'l‘m thereby thefe refolved Oily Particles are reconveyed into the Veins, and re- P£2123.iiifli l‘i1 allociate with the Blood and Snows" Nutricim, to give a fupply to the Ali- Eiiizdhtylsrdi: mentaty Liquor, when expended in Acute and Chronick Difcafes, which "qumm hath been often difcovered in Humane Bodies, when opened after Death, and diligently infpeéted with curious Eyes. In great cetaceous Filh, as Whales, Porpeffes and the like, great propor= tions of Oyl are conferved in numerous Vefieles, as fo many Recepta cles feared in a Membrane (not far remote from the inward furface of the Skin) and may be called Oleofa, in the abovcfaid Filh, thcfe unconcreted Particles are of the fame ingeny with the Fat of Men, and other Animals, as being of an unéhious, inflamable nature. A molt learned Author is of this Senfe, That Fat being Colliquated, and flowing with the Mafs of Blood, is unnatural; which is one reafon, faith be, why Fat cannot be generated out of the Vital, but Nervous Liquor: Iconfefs in Difeafes, when Fat is melted by an over intenfe heat, and re" ceived into the Veflels, it may be truly called an unkindly Liquor, and no proper Fat: but when it is originally In folutir I'M/affix, as it Were the creamy |
