is much inlarged , and the Animals themfelves are figur- 
ed in fome ot them; by which a great objed:ion is an- 
fwered, of thole who affcrt aeqaivocal generation , for 
that thefeare incloled in the Rock, every one inafiri- 
gle hole of.its own making, fo that it was difficult to 
imagine how they could copulate ; but by the figure we 
arc eafed of this doubt, for each ^/zm^?/ hath a long bo- 
die naturally exerted and extendable to a great length, 
as may be feen if they are put alive into water ; fo that 
we may well imagine, they couple not unlike earth" 
worms ^ which come out of the ground for that purpofe, 
And extend as much of their body as is neceflfary to 
mcttaMapes which if it happen to be near^ their bo- 
dies aremoft within the ground, if farthar diftant, they 
are acGordingly extended. 
And after this manner we muft think of the Solen kind; 
which are afort of fhell-fifti deep bedded infand, as the 
other is in the Rock : thele, I fay, rife up at certain dea- 
fens, and by the like body extended, copulate. 
AN ADYtRTISEMENT. 
All perfons that hzvc the ydums ihcic Tray^a^i^ 
ens intire, are defired to add a ftroke in the title page 
of the preceding one to this, and make it the XII Vo- 
lum ; Mr. OUenhir^h hzving publiftt 4 TranJaHions af- 
ter hii Eleventh Folum , to which, the fix, let forth by 
Dr Gr^n?, .being added, as indeed they ought, for that 
they carry on the old number ; they may well pafs for 
the XII Folum : fo that the two laft, for the years 16^ S 
andH^84 muft be accounted the XIII and XIV Volums.
