fion thefe Joynts, their dimenfions will be altered; 
which is moft apparent in them when alive. That like- 
wife there is a great difference of thefe Joynts in the vari- 
ous Species of this Worm i for I think there are more forts 
than one. And as to the differences of them there are thefe 
I have taken notice of. i . That iu moft tht Joynts gradually^ 
and very fenfibly encreafe in length. But in a vaft quan- 
tity of this Worm voided by a per fon here in Town, but 
in feveral pieces, a^?, 4, or more or fewer yards long> 
1 obferved for a great length the Joynts much the fame ; 
but fuppofe ] faw here neither the head, nor Tail. 2. In 
fome thofe orifices^ which I tdktioimouths» were placed 
about the middle of the Joynts, ox\t\\t Edges ^ in others, 
about the middle of the of the Worm, near the Joynt- 
ings. 5. Thefe juttings, or lips of the upper Joynts, c- 
ver the lower in fome, were plain 5 inothers crenatedi in 
others, the great protuberatings at the fide rendered the 
the whole Worm ferrated. 4. Ufually the fame Joynt is 
much of a bignefs throughout 5 but the upper extream 
fomething lefler than the lower. But in one I took out 
of a Dog, I obfeJved that towards the TaiL the upper 
part of the Joynt, by which'twas fattened to the foregoing 
Joynr, was very flender,- in the middle broad, and to- 
wards the other extream grew Taper again 5 fo that it did 
well enough refemble the which (g) Cornel Gemma

by Aldrovaudus i Spigelius , Sennertus, and others. Not 
that the whole ^For;w, ashehasraadeit, wasfo; butone- 
ly fome of the laft Joynts. And in another I took out of 
the fame Dog 1 could not obferve the fame thing ^ as neith-

about two yards long ; whereas thefe were each but about 
a foot or foot and half long And this leads me,to confider
