his Body, and obferving the Blood that flowed from 
thence, I difcover'd abundance of Globules in it ^ and 
cutting off part of the Leg of another Spider, I found 
more Globules there, tho I could not perceive any Cir- 
culation of the Blood in the Legs. 
I have often feen a Spider hanging down from a 
Branch of a Tree by a Thread of his own making, and 
holding faft by one of his Hind-Legs, which has three 
particular Claws, two of which are at the very end, and 
each Claw is armed with (everal Teeth like Saws, that 
towards the joyning with the F®ot grow narrower and 
clofer together, and where the Thread it has fpun, may 
be clofe twifted, juft as we fee in a Pully, which in the 
beginning is wide and large, but the longer it grows the 
narrower it is, in which the Clock-makers put their 
Lines, to faftenthe weight thereon. I thought it necef- 
fary to let the Limner take a Draught of the Claws^ in 
order to reprefent the thing more lively. 
Fig. I. ABCDEF reprefents a fmall part of the Leg 
of a Spider, BCD ftiew the two extreme Claws, arm'd 
with Teeth like Saws, E the third that hath no Teeth, 
which Claw I fuppofe he ufes on feveral accounts 5 this 
is certain, that when the Spider does not wind himfelf 
by his Thread upwards, but runs along his Web, then 
he takes hold of the fpun Thread with this third Claw. 
The above-mentioned Spider is provided with eight 
long, and two (hoirt Legs 5 and thefe laft ftand out on 
each fide of the Head, having fuch Claws as are before 
mentioned, notwithftanding what fome fay, that the 
Spider has but eight Legs. 
Moreover, I difcover'd eight diftinft Eyes, two of 
which are on the top of the Head, and given him to fee 
what pafles above him. 
Below thofe were two other Eyes, to look ftraight 
before him.
