Opening thefe Creatures anew, not thofe that were 
come to their full Growth, but thofe that were fo 
fmail, as that 25 of them would make but one great 
one, as I had taken out of the full grown ones the 
young, in which I did not only perceive the fhape of 
their Limbs, but could alfo behold very diAindly their 
Eyes 5 fo alfo out of tlie faid little ones I took feveral 
fmall oval Figures, which were very Tranfparentj and 
without all doubt would have become living Creatures^ 
tor when I diffefted fuch as were a little bigger, and 
that gradually, I found that the oval Figures were alfo 
proportionably Greater, fo far that the little Creatures 
were compleatly grown, and in a ftate to be Difclofed 
or Brought forth. 
You know Sir, that my Hypothefis is, that no Crea- 
tures that have Life, can be produced by themfelves, 
wherewith I imagine that many have been fatisfied, 
efpecially fuch as have feen what I have already ad* 
vanced about the Seeds of Plants. 
Now let us confider the two forts of little Creatures 
that were found upon the Leaves of the Trees, the one 
fort being Green and t other Blackifli, and the Analo- 
gy or Similitude of their Generation with that of thofe 
living Creatures that are found in the Seed of Males. 
As thofe little Creatures which we call Lice, are im- 
pregnated, tho in their Mothers Bellies, with a Semi- 
nal Matter, from whence other Creatures of the fame 
nature are likewife to Proceed, fo alfo the Creatures in 
the Male Seed quit not their ftation in the Tefticles of 
Animals, without leaving behind them other little 
Creatures,or elfe fomeSeminal matter from whence their 
Likenefles are to proceed, and that wichout Copulation, 
wherein they agree with the before-raention'd Crea- 
tures. 
Now we obferve in thofe little Creatures call'd Lice, 
fomething that does not occur^ as I know of, in other 
Crea-*
