quickly starveit. Besides, sincc it nuzzles its Head so deep intheCoatsofthe Intestines , at that time at least, it may be thought incapaMe of getting-ftarce any thing at all. But the Use I havc aflign’d that Part, I am aptto think, will satisfy others, as well as at present it does my seif. Thcre-fore4- Whyl think thosc Onfices Mouths is, because I cannot think whatthey are besides. For to take them forso many Vents of their Excrementwould be moreunrtasonable, since ’tispure Chyle which they receive; wh:chwill not afford much, at least so grols an Excrement, as to need so manyand large Orificesfcr the voiding it. And why so many Anus’s when butone Mouth? ’Tis easier to imagine them Brcncht*, or Lungs-, which in ln-sccts are observ’d in all the Annuli , or Joynts of the B >ay j but withall Imust observe, with how much disterence from our Subject. For in themyou (hall constantly see these Ori/Scwof both lides ineach Annulus, but in ourWorm , never but of one siJe ; In thole, they are not near so open,and large,as in this Worm, even so much, that I cannot sce how it can be avotded, butthat the Chjle must flip into them, and so spoil them for being Lungs ; Andindeed, whatllsecanwe imagine of such here, which must almoll constantlybe occluded, either by Filth or Chjle. If I misrcmember not, by preslingthem gently with my Fingers when fresh, and Turgid, I observ’d Chjle toissue out of them. So that I think I have little reasbn to doubr, that theChylous Sediment in the Spirit of W ine, I had immerged them into, camehence. Upon the whole, what I have here offer’d, I think, is sufficient tor end er my Conjecture Probable. And yet I have more Rcasons to add whythese Orifices should be Mouths ; because the Joynts when broken of, yitstill do Live ; and that too, as may be thought, for some considerab'e time;which theycould not, unlefs they had Mouths in each, which might re-ceive the Aliment for thesopportof it. Which brings me to the Last Par-ticular I proposcd, for Disonminating this Worm from all others out of theBody, and shall now Discourse of.

It has been stiffly maintain’d byAuthors of great Flöte, both Modernas well as theAntients, That the Worm it ftlf scare c Lives and is only aSfolium of the Intestine , or at least, it is not One, but many Worms, in-cluded in that Membrane. But such Opinions seem wide of the Truth : Formany Phyfitians have observ’d it to Move , and therefore to be an Animaland Alive. And a remarkable Instance I had of it, in that I met with uponDiflectionof a Dog in the Theatre of our Collelge ; wherel particularly ob*serv’d the manner how it perform’d its Motion, which was very plealing,and in different R>rms. For though all was persorm’d by Contracting andfliortning the Jojnts ; yet someiimes it rendred the Body, that was Fiat,Round and a Cylinder ; other times it made a deep Hollow or Concave ononeside, andaConvexon the other; butmoft times therewasa Bellying outat the Edgcs, about the Middle of the joynts ; and tho’ that part towards theHead was very Slender, yet upon Contraction it would become as Broad as thelast JoyntsIYfüs Contraction of the Joynts I sometimcs observ’d,at so veral placesatthe fame time at somedistance from one another; which must needsmuch ad-yantage its Progressive Motion; iince being of so great a Length, otherwise it
