When I had open’d the Body, the 'Tumor appear’d to be nothingcm^ iLmtbe Cacum dilated; its Membranes were outwardly fmooth, and of thefämeColour with the Intefiines without aluration, and füll of Veffcls ofali forts. The Ikon laid along the Tumor , bcing flat against it, and re-turn’d to joyn the Colon as is usual • so the Excrements had the liberty topais from the Ikon to the Colon , without entcring into it. I found in thisTumor about z Chopins (or Quarts ) of Greyifli Matter, without Smell,and of a Consistence rathet Liquid than Thiele. The Interior Membraneswere very beautiful; and ali the parts of the Swellwg , as weil as of theneighbouring Organs, appear’d very found.

I could not difcover any Hole, or Communication, this Tumor mighthave had with the lleon , yet fome there must have been in the beginning bywhich it diftharged its gross Excrements; but aster this Evacuat ion I bs-lieve that this Opening was stopr, and that the sides of this great Bag,which had come dose together by the going out of this gross Matte r, did bydcgrees streich and open themfilves to reeeive this Hereiogentous Stuff, whichI found there, produced either by the Glands of these Parts, or fome Lym-phatici VeJJels which I faw there, or fome Fluid Bodies exprest from theChyle, or other Humours. The Compreision which the Tumor made on theBiadder, made the Urine run out as fastas it came in ; its Spbinffer not be-ing able to resist the Violence of thisLoad.

XXXIII. Mr. Knowles being call’d to open a Youth, who dy’d, as was neCxcumsuppos’d, of the Cholick and Convolvulus , found the Cacum vastly extended, '^ n ss n ‘tha. Cl .»no stuft with abundance of Cherry-Stones, which were the occasion of his Mr.

XXXIV. We have observ’d (among many other particulars in the Guts) TbeVs eo y t b {the Ufe of the Intejlinum Cacum to be subservient to that of the Colon and intestinum e*-FtClum ; which is manifest in such Animals, whtre Nature intends a certain LiS? ^ Ds,Mmrd Determinate Figure to the Excrements. p- Sosi. ,s

I underfland by Determinate Figure, 1. The Excrements divided into „.iss-p- 45/.many fmall parts of a like Shape ;such as Sheep, Deer, Conies, Flares, Rars,

Mice, Horfes, Caterpillers, fome Snails, &c. do naturally void. z. Ina greater Latitude, I oppofe Figur’d Excrements to Liquid, asC. Celsus infome place doth: Thus the Dung of Pigeons, Geest, and Men, Cats, Dogs,

&c. may be faid to be Figured. Now the Cacum , in my Opinion, is sub-servient in fome meafurc to the Figuration of both, but molt Manifest inthe first kind. My roeaning is, that probablythe Use of the Cacum is tokeep the Excrements, which fhall paß into its Cavity (and I believe all, ormost part of them, do so in sound Animals) so long tmrill they are soffici-ently drain’d, bak’d, barden’d, or of a due Consistence (as Clay is tem-pered fortheMold) to reeeive the Figure to be given it from the Colon and-Reflum. This Use I sey of the Cacum, stems to me to be much moremanifest in such Animals, as have Figurcd Excrements of the sirst kind.
