eunt is very large, more Capacious thanthe Stoinach it leis. But its Use inteoeiving the Excrements, or cxhaulled Chyle , is not more apparent, fromits large Capacity, thau that other ot farther drawing and Tempering themto a Stiffneß, for the Service of thc Colon, from the admirable Contrivanceand Structure of thislatterGut, which is a Phänomenen that deferves furtherConsideration : It is, I fay, to be noted,rhat immediately under thc Valveof thatGut, in this Animal, are certain Spiral Fibres, which make a kind of Screw.N ow it feems to me, that the Excrements, aster they are brought to a dueConsistency by the neceffary Stay they make in the Cacum, and being car-riedout thenceinto the Spiral Foldings, or Screw, of the Colon , cannot de-scend in a perpendicular, as formerly through the small Guts, but stili gen-tly glide, and that very leisurely by the winding of the Screw; whence a-riscs the Figure. And I am apt to believe, that if the Cacum of a Rat, orany of the first kind of Animals mcntion’d, was ty’d up, or otherwise hin-dred from its Receipt, the Animals would unavoidably fall into a Diarrhaa:there being, 1 fay, no Reason, that 1 can fore-sce, why the yet Liquid Ex-crements, or exhausted Chyle, such as we constantly find it, even at the verybottom of the Small Gut, Oiould stop at the entrance of the Colon, andnot spcedily glide through the Screw, in a downright Descent; that is, eludethe Device of Nature, and make the Configuration of that so curioufly con-triv’d Part uscleß ; we, I say, lüppofing the Experiment to have taken awaythe neceffary Diverticulum and Repository of the unprepared Excrements, intying up the Cacum

I know not whether the Observation will hold good in general Terms, be-cause, I fay, I have not yet purposely examin’d divers Animals in Nature ;m. That wherever there are degantly Figur’d Excrements of the firstkind, there is ever a Capacious Cacum', and on the contrary, the lefia apcui ately Figur’d and myre Liquid thc Excrements of any Animals are, theleiser the Cacum or none at all. This is cettainly true, that fbme Animalswhich are naturally loose, have no Cacum at all, or very little, as theTalpa, the EchinusTeneßris , the Guloj and amongst Birds the Wood-pechcrKind, the HawkYCuiü, &c.

We sorbear to öfter fbme Doubts we have, concerning Nature’s End in theneceffary Figuration of the Excrements in fbme Animals; as first to preventLiarrbads-, Seondly to abide Hunger the b:tter, thus Snails in Winterreih with füll Intellines; Thirdly and chiefly to heighten the Fermentarimand L'igeßton in thc Stomach and Small Guts.
