vels therein, tho* they have much advanced the cloftrine 
of umvocal generation and bid very fair for the explod- 
ing of that, too eafily received^ and common error, of 
their produftion from putrefaHton , yet one great difficulty 
ftill remains with me, how to account for feveral of thofe, 
that are bred in Animal hodks not fuch as we may fuppofe 
to be hatched from the^^j-of the like kind, that are re- 
ceived with the foodor other ways but of whom we can- 
not meet with a parallel, or of the fame out of the 
body, in the whole world as is known befides. I (hall 
inftance onely in two, the LumbrictM Latm^ and Teres, Of 
the former I fhall give at prefent onely thefe remarks; 
wherein it^s difference from any other does more remarka- 
bly appear.i.being/^?^.2./oy;2/f<?^after a peculiar manner.^, 
the great difproportion of both extreams. 4. the vaft length 
'tis often of. 5« the ^^Wfo remarkably befet with hooked 
Spikes. 6. what has never that I know of, been remarked 
of this> or any other Infed or Animal in the World be» 
fides; the great number of Ma/z^^j- it hath ; more than 
the Poets fain*d5n^r^/^ had hands, or Argus eyts^ 
in every Joynt one* 7. Th^t^ny part of the body being 
broken off from t he reft* fhould ftill remaiaalive , and 
thrive. 
All which particulars^ befides what others may be added, 
if duely confideredr will render it difiicult to give an in- 
ftance of the like out of the body, from whence, or from 
the Seed of the fame, it may be any ways thoughts this 
may be propagated here. 
My other Inftance is the Lumbricus teres Intejlinalis 5 
which tho' it holds more with thofe called Intefli- 
na Terne^ or common Earth-Wormes^ as totheoutWard 
fliape and form ; yet within are vaftly different 5 as by 
comparing the Jnatomy of both , will appear. AW 1 
very much queftion, as to the icdntrivance of the inward 
Organs, whether We can meet ^ith^ any paraIlel ofit> in 
the World, ouroftbeMtrrfrr^w^'^fi^ bodies, be-
