Show Booch. Part 11 L C H A P. Book l. Part l l l . Of the ‘U/e 9f the Livers 4,6; is broken a: ' lithe \Valls of the Heart and Arteries, in repeated Pulfatia on 5 why,"- n the (Iliytne is embodied with the Blood, and by degrees is more and r.‘ malted y its converfc with the Vital Juice, into which at XIX. llfli it is y "f ‘rly Allimilnted: Whereupon We may infer with good realint, that Bl Of the ‘U/e of the Liver. ficatic-n, ' tual l‘vfor other sanguification is not male in the Liver. ' Aving Difcourfed the great variety of Veffels, and the numerous Glands, as a compofition belonging to the Liver, my Defign atthis time, is to thew you the Ufes of it: One of them, and a very great one too ( if true) afligned to it by Learned Anaromifts, is the office of Sanguification; which may be confidered either in reference to its Primary Gene- ration, or its Secondary Production, or Repair, when it is much decayed in a conllant Circulation, or Local Motion to or from the Center. Wood is term rated by the As to the firft Formation of Blood, It is attributed to the Spirit of Life, _ refiding in the Seminal Liquor; which may be clearly feen in an Egg, [3: .'_ upon by a Hen, before the produétion of the Liver, or any other Noble part, nay, before the firll: Rndiment of the Heart7 or Blood in it : By reafon the Vital Juice, before it putteth on its Purple Robe, beginneth to quit thofe parts of the Egg (with which it was lately confufed) and to form divers Ramifications, which afterward appeared to be Veins, and thefe ftreams of Life did concenter into one Point, the rough draughtof the Heart. As fo‘on as thefe Rivulets do unite, their Inteftine Motion commenceth, whence is propagated a gentle Ebullition of the Vital Liquor, fomewhat fwelling its confines; and becaufe it cannot make its retreat the flame way it came, it frameth new Channels, the Arteries, through which it maketh good its Retrograde Motion, from the Center to the Circumference, from the Heart to the ambient parts of the Body, and this Vital Liquor is carried forward and backward through the various Apartimcnts, before it is hued with Red; which is not efléntial to Blood, and is clothed in a whitilh aray in its Infancy, and when it arriveth to greater perfection acquired by Local and Inteltine Motion, it is adorned with a new habit of Scarlet. So that upon a firift inquiry, the Blood receiveth its firft conception not in the Liver, or any other Bowel feared in the inward receffes of the Body, but in the Exterior parts, near the furface of it : And in the firfl: generation - of Blood in a Humane Foetus, its birth beginneth in the ambient parts of the Embryo, in the Cation nearly feared to the concave furface of the uteri", by whole heat, colliquation is made in the circumference of the Genital Juice, where the Vital Spirit beginneth firflt to exert it felf for fome little fpace, and then .tfiheth its progrefs to the inward parts, to the Dancing Point, the firlt l'xudime‘nt of the Heart. So that the Liver is not all concerned in the full Formation of the Vital Juice, whofe birth doth antidare that of the Liver and Heart. And when the Blood hath much exhaufted its Spirits, in its conPtant Peramhulation from the Heart ( a rare engine of Motion) to the utmolt COHfine: of the Body, and from the circumference to the center, in a hack mo- l7 i malted: Blood, in which is founded the principle of Sangui- repair the loft and abfumed parts of it made by perpe.. A free Tranfpiration; and the Liver, or Heart, or any iiiigsi-‘isdtih A :1, cannot arrogatc to themfelves the Priviledg, or "WHEY i .» . of Sanguification, which is the true attribute of the Se~ ililltllalljlflfor iuinal Liz; a, , {Exiled with extraneous heat, in reference to the Hill: Forma- g‘lgl,jfif;‘;;fd tion of Blood in a Foetus; and afterward in order to a fecond Production, llgfjbym the Blood is principally concerned and not the Liver (or any other of the "lid ("caulk Noble parts, which are highly acted with this Excellent Liquor) by reafon :Silaftili'c. the Vital juice hath its generation in the Seminal Liquor, before the Hrl't Rndiment of the liver, and hath its fecond Production from Chyle, as its Mum}; Sub/tram, whofe proper Veffels have no entercourfe with the Liver, upon which necount this noble Bowel (though very uleful in other regards) is [Lelndcd from the office of Sangrlilicatiori,xxthiCh may be truly attributed on- ly to the innate principles of the Seminal Juice, and thofe too of the Blood, as having a fruitful faculty to prOpagatc it felf, as confervarive of the choice [Economy of Nature, in the great variety of Animals, wonderfully made and prefervcd by an All-wife and PoWerful Agent, who hath inflituted this Noble part , the Liver (though not for Sanguification) yet for fome other important Ufe; which is evident, if we {hall behold and admire the greatnefs of this Bowel, as a curious Conipage, integrated of variety of parts, fet together in excellent order, as one miniflerial to another; which fpeaketh the great contrivunee of the Omnipotent Architeét, who hath not formed the choice Fabrick of the Liver to give meerlyan Attribute to himfelf, without any delign of doing good to others, of which the All-Wife Creator cannot be in any \xife guilty, wherefore he molt prudently conPcituted the frame of every part, as tending to fome proper ufe. The liver, though it is not inf'tituted for the Produétion of Blood, yet trimester: hsth an Office belonging to it, of another Rank, and is defigned by Nature "mm .rculatethc for its refinement, aceomplilhed by variety of Velfels, percolating the Mafs gjgdéfbvc‘fj‘ of Blood in the glands of the Liver; which is performed by various de- 1'61:- grees, and is firlt prepared in many other neighbouring parts, which impart: different Ferments to it, as predifpol'in the Vital Liquor, in order to the fecrction of its Recrements in the Parencfiyma of the Liver. Blood is difpenfed by various Branches of Arteries, fpringing out of the Defcendent Trunk of the Aorta, into divers parts adjoyning to the Liver, Which do all concur to the depuration of the Purple Liquor. The Cil'ilflc and lWefeuterick Arteries do convey Blood into the Ventricle, TheGiandscf and Intellines, in \rhofe glandulous Tunicles, the Vital juice is fecerned and "hwwnmh Liver, at! from the Fszccs of Pituitous Matter, as the reliques of efizte and indigefied 3?}cfljgigl:‘° Chymc ( not allimilarcd into Blood) conveyed through the Pores, relating #:1230517; to the glandulous Coat of the Stomach and Cuts, to line the tender Fila- firthctpcrcm ments of their inward Tunieles, thereby fecured againf‘t bilious and [harp Re- 31233."
