of the Spiders Bod}%can't be done near fo foon,nor be im- 
mediately congealed in theAir,as the thin and fineThreads, 
a hundred of which being put together, will not, in my 
opinion, make the hundredth part of the Thicknefs of 
one fingle Hair of my Head : in a word, we may hereby 
difcover the Wifdom of God in the Perfeftion of his 
Creatures, tho we little regard fuch a Thread as this, be- 
caufe it efcapes our naked fight. 
Whilft I made my obfervations of this Infinite number 
of Threads, I was quite ^amazed to confider the wonder- 
ful Inftruments that lye hid in the Womb of the Spider, 
thro which fo many Threads muft feparately proceeds 
And tho I could not imagine that I (houid ever be able 
to dilcover this great Myftery, yet I proceeded to the 
Difledion of the Body of one of the largeft Spiders I 
could gef, and very curioufly inveftigated each part of it, 
and at laft, to my great amazement, I difcover d thevaft 
number of Inftruments, from whence each fingle Thread 
proceeded 5 yea, the number was fo great, that I judgd 
them to be at leaft four hundred 5 but they did not 
lye by one another, but were divided info eight Diftindt 
Parts or Inftruments 5 io that if the Spider fet all thefe 
eight Inftruments to work at once, there would proceed 
from the fame eight particular Threads, which were a- 
gain fubdivided into a great number of fmaller ^ but one 
of the great Threads would be thicker than the other, 
becaufe one part of the Body would produce twice as 
many Threads as the other )uft by it. 
When I viewed the difleded Body with my Microfcopes, 
and the place where the Threads come out, I found that 
they were (hut up by five diftin6t parts, which at the end 
are pointed, and caufe fuch a fort of {huttings but from 
the middlemoft there comes no Thread out* 
The other four Inftruments, which flioot out "thefe 
Threads, are covered outwards with thick Hairs, fo that 
all ^he fmall Inftruments lye inwards 5 for this reafon(as
