leaving 6 or 8 ©therein the aforefaid Glafs 5 and I took 
the afore- mention’d blackifh Ammalcula out of the Glafs, 
and I carried the Glafs Tube, in which the two Eggs 
were, about with me in my Pocket, that 1 might fee 
how much fooner thefe would be hatch’d, than thofe 
which I left upon my Desk in a great Glafs Tube : And 
I difcovered upon the 15th of J une young ones hatch’d 
from the Eggs which I carried about me 3 as upon the 
20th, were thofe in the Tube that lay upon my Desk.

that one could not fee their Bodies. 
In the beginning of Augufi , I view’d them again, but 
could not perceive any flying Creatures, as I expected, 
to be changed from the creeping ones : Wherefore I 
cut off a little of the Cork in two feveral Places where 
thofe creeping Creatures had been digging 5 and then I 
difcover’d one Ammalculutn , which had changed its Skin 
for the laft time, and lay (fill upan the hinder part of its
