Eggs, mixt with dry Earth, in which Earth the Eggs 
were found, and whole Axis was almoft the Fifteenth 
Part of an Inch, together with a Defire to inquire what 
living Creature would come out of thera. 
I did feparate fome of thefe Eggs, and found a thin 
Moifture in them, mixt with round Bubbles ; the reft of 
the Egg's I included in a Glafi, but the internal Matter 
dryed in a few Days away, and the White Membrane 
of the Eggs (which was very tender and fofc) wrinkled

brought me again fome of thefe Eggs, with which I did 
ssbetore, but I did not get any thing out of them. 
Now in the begining of the Month of July^ the fame 
Friend brought me a greater Quantity of thefe Eggs, 
that was mixt with a Handful of wet Earth. 
In the mean time it came into my Mind, if the dry- 
ing away of the Moifture of thefe Eggs was not the Rea- 
fpn of their not bringing forth a living Great ure,becaufe 
iheEggs being in a dry Earth,grew fruitlefs,and that the 
Nature of thofe Eggs requireda moift Earth, and for thai:
