the fame Vessels fl thinlc) in as great Numbers as at first (perhaps a bove80) but the Colour of most of them was chang'd, for they were allnow Pellucid: Same 3, or 4,which I at first cut asimder for my betcer Enquiryinto the White Chyle contain'd in them at that time, being Limpid togctherwith the rest. The fime thing socceeded in a Dog kept Fasting 2 Days,and thcn open’d 3 Hours aster he had lapt 3 PintS of Milk, part of whichwas seen in the Stomach of the Dog : About 15 of the LaBeals, arisingfrom the. Duodenum, were White ; aboveioo, proceeding from the Inieftt-mtm Jejunum, and Ileon, were more or less 'Transparent ; as also were tholeof the Duodenum at the latter end of the Operation.

The Experiments of the ist. kind do sofficiently prove, That the LaBealsconvey not only Chyle (which refalts from Aliments lately taken into theStomach, and may be called Liquor Novttius,) but also another Humour se-.parated (as is most probable) from the Blood, ard now returning to it a-gain } which (by means of the afore-faid Experiments,) may be seen pure-ly by it self, without any Mixture of Chyle with it. And it scems not un-reasonable to derive this Liquor Refluus, or at least part of it, from theHollow of the Intefiines ; if we confidet that the Pancreas, and GlandularumPlexus Fragiformes, (not to mention the Laver) do daily discharge a Liquorinto the Intefiines ; which (considering that Dogs, aster z Days Fasting,will, as I have osten obscrv'd, have very hard Faces in their Intepma ReBa)■we cannot well disposc of any other way, than by saying, it re*entcrs theJilood by the LaBeals, and is that very Liquor which conduces to the ma-king körne of them appear Transparent aster so long a Fast. It ftems alsoprobable from the fame Experiments, that the Latleals are very seldom, ornever, all empty at the fame time; for tho’ the Chyle flowsonly in certainTides, or Flafhes, pro ratione Ingestorum , yet the Liquor Refluus, run-ning in a more constant Stream, docs when there is no Flash of Chyle goingin, keep the Latleals from being absolutely empty. And ’tis farther evi-dent, that this Liquor Refluus is, in its own Nature, Transparent, and paffessuch through the LaBeals , aster long Fasting, when no Chyle is mixt withit; which is no inconsiderable Step to the making out of my Proposition, ifwe recount how long, and how osten, very many Quadiupeds, besideMen, do Fast from all kört of" Aliment ; during which time aster the Chyle ofthe last Meal, or time of Drinking, is all mixt with the Blood, we mayliippose that this P ellucid Liquor Refluus , gocs alone into theLaBeals.

The Experiments both of the 2d. and zd. kind, stem to intimate thata great part of the Chyle it fest is, in irs Journey thro’ the LaBeals, al-rogether Limpid. Agam st which it may be Objected, That körne of theLaBeals were in a like manner Pelluad in all the Experiments of ali the.3 Kinds, and therefore it does not appear but that they may be filPd with aLiquor Refluus in the 2 last Cases, as well as (for certain) they were in thefirst Case. To this Objection, beside what may be Anfwered from theExtraordinary Number, and Fulnesi of the Lmpid LaBeals in the twolast Kinds of Experiments, comparing diese Vessels with thoseofthe fame
