fome oi which are fo thin and tranfparent, that I Iiave 
often feen their Limbs diftindly within, and thei. nu* 
merous eyes, of which more hereafter. 
Now if this Figure and parts of a Fly were rot ? 'du- 
ally included in the Worm, fuch a Tranfmutation 
would have been unconceivable ^ fo it is alfo with the 
Creature in the Male Seed, but it is impoffible for any 
man to penetrate into the fecret parts of fuch a won-

If we fhould confider the Tail of one of thofe afore- 
mentioned Creatures, we muft needs be aftonifht at the 
incomprehenfible Number and Smalnefs of its Pans, 
efpecially if we conclude that fuch a very little Tail i§ 
provided with as many Joynts in proportion as the Tails 
of larger Animals, otherwife it could not move nimbly 
on every fide as it ought to do 5 and again, that every 
one of thefe little Joynts confifts not only of Mulcles, 
but alfo of Arteries and Veins, which derive the Nou- 
rifhment down to it : I fay, if we confider this, and 
the filial nefs of ail the other parts of the Body, we 
cannot fufficiently admire the v/onderful works of 
God. 
In the Summer I obferved the Seed of young Cocks 
that were not arrived at their full grov^th ^ bat I in- 
tend to enlarge my Obfervations before I fay any thing 
more of that matter. 
As I aim at nothing but Truth, and fo far as in me 
lies, to corred the Errors of other men, I hope that in 
fo doing no body will take oflence, tho 1 freely Cenfure 
his Faults ^ arid if others will take the fame freedom 
with me, and point out the Miftakes that occur in my 
Obfervations, I fhall .efteem it a fervice 5 and the ra- 
ther, becaufe it is the way to attain to a greater Accu- 
racy and Exaftaefs in thefe fort of Speculacions.
