cording to his allcdged experience,it is turn'd into Chjle : which he affirms , he 
hath difcover'd,by taking an Egge from under a brooding Hen, v/hen the Chic- 
ken was ready to break forth' , and when he was looking for the pafTage of the 
Tolk^, out of Its integument into the Liver, by finding it pafs thence int© the In- 
ff/^/KT^as he found the ^''to to do by the mouth into \ht helly. Whence he 
inclines to infer, that^fince every j^s takes in at the rriouth the liqaoric 
fwims in, and 0nce the Chicken receives the vphite of the Egge into the momh^ 
and the/o/^ by the new difcover'd dM-Vtus into the Inteft ns^xl cannot be certainly 
made out, that a of the Chjle is conveyed into the Ltz/fr, before it pafTes into

produce Experiments to evince their Ratiocinations.

tomico'tnedicajn thisTrad,the Induftrious Author , after he has enumerated the 
various opinions of concerning the ufe of that kernelly fubftance- 
calPd Pancreas (\^ Bnglifh^rhQ Srpeetbred) endeavours to prove experimentally 
that this Glandule was not form'd by Nature , to feparatc any Excrementitlons 
humor.and to convey it into the Jnteftins^ but to prepare an ufeful juyce out of 
the Blood and Animal fpirits.of a fomewhac Acid tafte , and to carry the fame 
into the Gut, callM Dtiodenum, to be there mixt with the Aliment, that h3.s been 
in fome degree already fermented in the Stomack for a further fermentation, to 
be produced by the conflux of the faid acid PancrcAtick^ juyce and fomc Bilions 
matter,abounding with volatile Salt^caufing an Effervefcence which done, that 
'Juyce is,togerher with the purer part of the nourifbment,carried into the Millie 
veins, thence into the common receftacleoi the Chjle and Lymphatic^ liquor^ and . 
fo through ihtduUus Thoracicids into the right Ventricle of the Heart. 
This Affertion,{irft advanced (faith the Author) partly by Gcthifredus Melius^ 
partly by Tranclfcu^ de le Boe Sylvins^ he undertakes to prove by experiments ; 
whi<:h,indeed,he has with much induftry^tried upon feveral Animals , to the end 
that he might colled fome of this Juyce of the Pancreas for a tafte: which having 
at lad: obtained, and found it fomewhat arid , he thereupon proceeds to deliver 
his opinion both ohhe cey^fl it ut ion and quantity of this S f^cc us in healthy ^mms^\sy 
and the vices ihereof,in the unhealthy : deriving moft difeafes partlj from its too 
great Acidity , or from its faltnefs^or harfhnefs ^ partly from its paucity or redun- 
dancy : but efpecially, endeavouring to reduce from thence, Tls 2\\ inter mitt tnt 
Feavers (of all the Phenomena whereof he ventures to affign the caufes from this 
Hypothecs) fo alfo the Gout , Syncope' s ^Stranguries fippiUtions^B'tarrhtas ^ Bjfcn-

the waies and remedies to cure the manifold peccancy of this juyce by Evacuati- 
ons and Alterations. 
This feeming to be a neVo as well as a conftderahle difcovery,it is hop*d,that o- 
thcrs will by this intimation be invited to profecute the fame by further experi-
