Ihe common Scorpion, and the particular parts

a The head jointed to the breaft like as in a 
lobfter, is confpicuous in the fore-part, in 
which are two {mall forceps or pincers, and

the breaft there are alfo two eyes, there be- 
ing fix in all: which may be plainly known 
to be the number of the eyes. 
5b Its eight hairy legs, each divided into fix 
joints. 
¢¢ Twocrooeked arms with pincers, each com- 
pofed but of four joints, if you except that

eyes, fome much larger than others: befides 
thefe there are, in the middle, as it were

naturally.
