1 have fcvera! rimes taken up the Male Spiders, that I 
might obferve their Seed, and have been tully fatisfied that 
that hide white Matter which I fqucez*d leveral times out of 
the hinder part of their Bodies, and which was fometimes 
as large as one grain of Sand, and fometimes a little big- 
ger, was nothing elfe but the Male Seed of thefe Crea- 
tures 5 I difcoveTd therein an infinite number of Animal- 
cidd, which continued fo long living, till 1 was wearied

an adual Copulation. 
Tis true, that in all the lafl: Spiders I could perceive no

the Male Seed was not yet Ripe enough in them, or it 
may be they had lately coupled before I took 'em. It has 
fometimes happened to me, that in the preffing their Seed

Since thefe Experiments I (hut up (everal Spiders in a 
Glafs Tube, and amongft others 3 Males and i Female to-
