almoft equally turgid* and alike filled with Ghyle in pro" 
portion to the magnitude of the parts. Now I cannot 
think that in voiding it can always be broken into fo ma- 
ny pieces h and if it be done fometime before, and they 
lye dead in the body, they rauft be emacerated, anddit^ 
ferent from what they appear. But that obfavation, I 
have already often mentioned of that Worniy ] met with 
ki the Dog, IdiflTefted in the Colledge Jhmcr doesfur- 
nifli me with fomething appofite to our purpofe. For 
hereabout the middle of the JVorm, it lay in the Ititeftine 
about a foot and a half from theTayle, or lower Ex» 
tream J I obferved two fmglQ jfoyfits^ about * of an Inch 
long^ alive^ and which continued their motion brifkly 
for i of an hour, or more in warm water. That thefe 
were broken off from the Tayk I nothing queftion ^ being 
in all refpeds fo like them. And that it muft be done 
fometime before , I am apt to think, becaufe they were 
fo remote from it. For they could not otherwifeeafily, 
being but fingle Joynts, make fo great an advance, being 
upon all occafions liable rather to be driven down , not 
being able as I could obferve any ways to faften themfelvs, 
and fo refift th^ forceof the defcendingi^/^r^j-. Which is 
the reafon when broken olt- they are fo frequently void- 
ed. 
Upon the whole I have been fometimes apt to think, 
what Analogy theremay be between t\\\% JoyntedWorm, and 
knotted. iHmits - of which each Joynt can fo eafily propa- 
gate its felf; And whether it may not be thought an y^w/- 
?nal JPlant'Animal or Z^ophyton bred in Ayiimal bodies , 
fince fo large, and frequent detruncations o^the .body3 
does nor deftroy the life of the Whole.^ Which I think 
can fcaice be inftancediuany Animal befides; ' \ 
But my here, is aot the^raifing of any 
but the enquiring into the truth of thofe of others, Ic 
being much eafier to fpy others faults^ then tp avoid, them
