Show Ofrhe Tat/yology of the Heart. Book ll. And in order to the more clear underfianding of the nature of Fevers, confifiinv in the various ill Crafis of the Blood( dilturbiiig the Motion of the Heart) Twill give you afliort Hifiory of the various conltitution of the Blood, as produétive of its Ebullition in‘the Heart.

Humwfi‘ cording to this Opinion, to folve the Phenomena that may occurr ; fo that it feemeth more probable to determine the Blood ( as Well qualified) to be one Liquor, confilting of Heterogeneous parts, and not of thofe different liumors, which do not confiitute the mafs of Blood, but are only accidental to it in a depraved habit of Body, in which three of thofe humors may be called Recrements of the Blood ( and not conititueiit parts ) ~which Nature cndeavoureth to fecern from it, and therefore it is more conlonane to i'teafon, and Senfe, not to believe the Blood to be made of many diftinét Humors, but one Liquor confil'ting of different pai'ts,‘pitu1tou's, framed of crude Thcmclan- indigefled Chyme, or bilious, made of exalted Qily Particles, or melancho- $13.1 {333:2 lick, compounded of Tartarcous, or earthy, Saline, put into a Fluor, as the "90¢ chief Spitituous and Oily parts are breathed out. . Hence fnring the four Conf'titutions of the Body, derived from the feveral Tempe‘raments of the Blood, when it is integrated ofdifioerent Elements, reduced to a good harmony in due proportion ,The confiitution of hot, Oily, and faline Particles not too much exalted, nor the grofs and fixed too much deprefled, and the folid and liquid Atomes well mixed, may be truly [tiled Th: finzui- the Sanguineous temper of the Blood, and is the rule from which the others i‘tii'iiiiifriii: may be termed more or lefs ill, as they have greater or leis deflections from it, KW" as being ill tempers upon which the 'Pathnlogy of theBleod depended). Thcmuimu, The FirftI will Treat of, is the Pitu1tous Confiitution, derived from m,""""""" cold, moil‘t, or grofs Aliment, not well concocted, for want of a fit Mcnflmum, gr m: mm. or good natural heat, whence proceedeth an ill prepared Chyle, conveyed thrbugh proper Channels to the Heart, where it being not well attenuated and colliquated,runneth confufed with the Blood, Without being broken into finall particles, by reafon of its over vifcidc fubftance, generating a crude mafs of Blood, which being imparted by great and lcfs arterial Branches to the whole Body, maketh a cold and moil't temperament, commonly called ‘Pituitom, feared in a grofs mafs of Blood, apt to be fiagnant, which produceth various infiamniations in reference to feveral parts, in which the crude Blood is lodged, oid. a @trimimania in the fubliance of the Lungs, and 'P/euritirin the rPleuriz; An Angina in the Mufcles of the Larynx; A Polypzu in the Ventricles of the Heart, and the Trunk of the pulmonary Artery and Veins, An Apoplexy in the fubltance of the Brain, and an Ana/arr" in the habit of the Body. ' ‘ Some Phyficians,and thofe Learned too, do conceive the Phlegmatick mafs of Blood to be compofed mi'ich of Chyle, or nervous Liquor, as being akin in colour and manner of confidence) Whereupon it being thick and indigeft- ed, when extravafated and Cold doth concrete into a white and difcoloured Cruor, or skinny fubl'tance, facing the upper region of the Blood, when it is let out of the Vein into a Porringer, and coagulatcd.

This Compage of the Blood may be made evident by ocular demonltrati- on which I [aw in concreted Blood, covered with a white Surface, almolt halfe an inch thick, which was integrated of many fine Membranes, as f0 many thin Flakes, conf'tituting this coagulated Syl'teme, framed of numerous Filaments, curioufly interwoven, and clofely fer together, which I difcerned by my naked Eye, without the help of a Microfcope; and alfo many finall network Plexes, interfperfed with Arm, or little Loculaments, affixed to the infide of the Membranes, as f0 many Repofitories of the ichorous Liquor of the Blood : And afterward upon a deeper fearch made into the more interior receffes of the Blood, I difcovered firfi a reticular Plexe, full of Cavities tied to the infide of the Membrane, conl'tituting the lowell; Membrane of the white vifcide contexture, finely wrought with interwoven Filaments, pinked with many holes, as To many allodgments of the Purple Liquor, divided alfo into many Fibrils, which runin length downward, making an elegant Compagc, befet with curious Embroidery, made up as it were of nervous Filaments, adorned with [nterFtices of divers Figures, as [0 many minute Receptacles, big with Red Liquor in the lower region of the Blood let out into a Veffel, and concreted; the firuéture of the Blood feem- eth to be more loofe then the Crult fwimming a top, as framed of Filaments endued with larger Cavities, which are receptive of the Red Craflament, or rather (as fome will have it,) a black melancholy Liquor the Faces of the Blood,in whofe Pores, as well as in the Interltices of the white coagulated Liquor, is lodged an alh-colourcd pale Serum, fomewhar refembling the concreted albuminous matter of the Blood, or the White ofan Egg. And to the oblong Filamentous Productions, propagated through the Red mals of coagulated Blood, are appendant divers fmall reticular Plexes interlining the fpaces of the long Fibres. And the Body of the concreted Blood being wafhed in divers waters, hued before with Red, whereby the Scrum being parted from its Recepa tacles (many Plexes making the fine Network) may be Icen arayed in White; and as they are longer and longer gently wafhed, the Whitenels coating the fibrous contextiire of the Blood, may be more clearly feen. . And belides theft: white and fibrous Particles, which are the tint Stamina, giving a bulk and body to the Blood, the moft eminent are the Red Particles, enclofed in many Cells and Filaments, and being highly attenuated with Motion, do intimately alfociate with the albuminous part of the Blood, and wholly obfciire it. ‘ In this Cryfialline Liquor are feated the fine volatil Salts (attenuated and difl‘olyed. by Heat and intefl‘ine Motion) which are thechief ingredients conl‘tituting the Ferments of the szcera, helping the Stomack and [nteftines in the concoction of Aliment, out of which a white tincture is extracted , the Materia Sub/tram of Blood. And it is very probable that the fibrous parts of the Blood are propagated from {mall Capillaments, which being united, do Confiitute many thin Filmes in the Body of the vital Juyce, and more thick and tough Membranes, cloathing the upper region of extravafated Blood. The Filaments are very vifible in the Concretions of Salt.
