But becaufel would be fully fatisfied in the matter, I 
took feveral Spiders that had not yet laid, and throwing 
them on their backs, I preft their Bellies, whereby I had 
not only a clear view of the opening, but by fqueezing a " 
little harder, I made a great many Eggs come out, and 
not the leaft moifture proceeded from the hinder part of 
the Body. 
This Experiment convinced me, that that was the 
place from whence ftie voided both her Eggs and Excre- 
ments. 
I thought fit to let the Limner draw fuch a Spider of 
an ordinary fize as flie lay on her Back, with her Legs 
contracted as if (he had been dead, in order to fhow, if 
pofTible, the afore-mention*d place. 
Fig. 7. ABC reprefents the Spider in fuch a pofture, 
and D the Hook. 
I feparated the faid Hook from the Spider s Body, and 
placing it before my Ghifs, I gave it the Limner to draw 
a6 it appeared to him.

are feen, which I imagine were made to produce a more 
than ordinary motion.

Body. 
I never was fo happy as to fee theSpiders couple ^ a cer- 
tain Gentleman told me that they coupled Back to Back 5 
but what fhall we fay, the Coition of Spiders mud difiFer 
fundamentally from other Creatures, fince their Matrix is 
placed in the upper part of the Belly 5 however it be, our 
Curiofity muft be deferred till next OSokr. 
I thought with my feif, whether the ufe of the fore- 
faid Hook might not be to range and placs the Eggs: In 
the faid Fig, 8. between F and G are two round Balls, 
but I cannot imagine the ufe of them.
