In the fecond Glafs Tube, which I had carried about 
me a long time,, the young Spiders that were therein did 
not live near fo long as the others 5 the reafon whereof 
was, as I conceive, that the warmth of my Body caus'd 
them to Perfpire more, and confequently to ftand in need 
of their Food fooner. 
Now I had in my Desk the Eggs of fix diftinO: Spiders, 
which I often view'd, to know when the young Spiders 
would come out of them 5 and on the 20th of M.yil ob- 
ferv'd the Eggs to change colour a little 5 and on the 
2 2d the young ones were Hatched, and lay foclofe to one 
another in the Web, that they took up bat-little more 
room than when they were in their Shells, and \ could 
. not difcover any motion in them, only they that lay out- 
ermoft ftirr d their Legs a little. 
Thus. I have given you my Thoughts and poor 
Obfervations about Spiders 5 which Creature, in the 
eyes of fome people 9 is fo odious or terrible, that 
they will not come near them 3 in which however 
we have difcover'd as much perfeftioa and hidden 
Beauties as in any other Creature 5 for when I took the: 
Flefliy Mufcles out of their Legs, and view'd them thro 
the IViicrofcope, I Vv^as aftonifht at their Tranfparency, 
and they feem'd to be one Body 5 but when I came^ to 
feparate them, I found that they were compofed of very 
long Particles, each confiding ot fo many Folds or Wrin« 
kles, that the Mufcle might be dilated or contrafted, as 
there (hould be occafion*
