( J34 ) An Aecount oq/ tkhee Bodks. I. De SECRETIONE I ANIlMALI Cogitata, Autb. Gull. Co le M ) .

This done, he procceus to ihe handling of the S,tbjctt itfelfi and here-he explaisfrJ'/!, \V"h/l t he ine;ans by thlt. b'ccreton si next, he ihews the fource of thctc Secrtionm:, tiz. the C'1itle and Blood; thefi, he ef:tiblifhes the Exiitct.e of ttle N'Erout Juyce, upon which his Ihpo::hif,s -mainly depends ; jurter, he confiders the previous Diipoiition of the Juvces for becretion, which he iaitih is inda:ced by an intefiin Fermcent,:ton; ctgain, he ailgns the Organ, by nature appointed for thi Oiice, which to him are none otiher bk:tt the Glandular Subftances of the BTo dy, to be found in all the parts thereof, even in tl e Skin itfelf; more-ovtr, hlexpoLnfs ti mainn< r how all animal Sect etions are perform'd; which he (ioti/11in gilrai, te,aching that general ly they ar.c all er:cte nImmiedi:tci y by erc./atn; henI, rin particular dillin ulithin Secrctions into Sipilpe or Pcr(z/dive, and into thofe that aare tM't, fanL._ thcfe atlin in ixo ExcrCve and Redui:z-" he affirms thle Si mp or Pe,1cfife-Secret:ns to be perfort'd by mear Perclagt;in, wherebr, upon : piuvious mixture of thc ft.rments :conventng fro'm ati p;rz, the texture of the Juyce is tb open'd, and it, pa.rcles to comninuted and diiCuciated, that any prope:ing foi'e i ipervltning, they will eafiiy l rJl:ndcr, and p:.fs .nto veilt s iutble to admit them: By hi' L.h way he efteems that the trajcon is made of the Chyle out ( 135 ) out of the Inteftins into the Milky v.fels, and that of the Nervous Yuyce out of the Arteries of the Brain into the Nerves. As to the Mixt Secretions, he will have them fo perform'd by a Ferment, as that by means thereof threc be imprcfs'd fuch a determintation on fo:ne certain particlcs of the Blood, that leaving behind others they readily pafs into the veffels fram'd for Secretion. And here he confiders, that if this kind 6f Separation were tranfacted by meet Percolation, nothing probably could hinder, but the more fubtile matter would come away, and the groffer ftay behind : Whe-refore to pr:ocure a recefs of the grofier parts, he calls in the help of foute iuch Ferment, as tnay precipitate thefe into the Secretory vcfi,>. On which occafion he dif:ourfes largely of Fe;,'mets, aiigring hem not only the Ufe of digejiing and elaboratling the Juyces of the body, but alfo that of/fcreting them. Where indeed hde takes pains to penetrate into the nature and properties of F'e;';ments, minutely examining,' Vh:-t Bodies are qualified for Fet mer ?ation; What difference there is in Ferments; and whence the fIeri ,. ntative Iower arifes; as alfo the Smalnefs of a Fermeliits proportion to the Body to be fermented, and the receffity of Lfme warmth to excite Fermentation: Explaining withal the Size and Figures of the parts of Fermenting bodies, which he teaches to be very finall, very angular, and exceeding diflimilar, affigning his reafon for fo doing. To which he adds the two main Differences he finds in Ferments, fome having an Expa(;^ive, and others a Preczpitating power; and having rendred the caufe from whence proceeds this difference, he afierts, that Nature makes ufe of theformer in fimple, and of the latter in mixt Secretions. After thi;s, he proceeds to fhew, What it :s that Ferments do confer to Secretion, and whence they are d-rived ? As to theformer, he alfirms, that there areJofie Ferments, that are precedaneous to Secretion, and able to loofen and fubtilize the mafs to be fermented, for the more ealie disjun&tion of the parts; but that there is an other, which immediately caufeth the vety adt of Secretion; which he takes to be the Nervous 'fuyce, without the direation of which he efteems there will hardly be made any adual diffociation of fo many different Subfiances, as Nature
