4^0 On a large Spiders Fangs* 
which lay concealed a Couple of exceeding 
fharp hooked Claws, which mull be greatly 
ferviceable in clambering, to cling to any 
Thing, or to feize the Prey. 
The Body was cruftaceous, having a Shell 
as hard as that of afmall Crab; the Tail Part 
was foft and downy : on the Back both of 
the Body and Tail the Hairs were fhorter 
than elfewhere. The two Fangs were ftrong, 
black, hard and horny, terminating and be¬ 
ing Parts of two fhort thick Limbs to which 
they were articulated, projecting from the 
Body diredlv before the Mouth. One of 
thefe Fangs magnified about three Times is 
ihewn at Letter I. They were not placed 
horizontally like a Pair of Forceps, fitted to 
catch and hold Things by bringing their 
Points to meet,as in mod: of ourEnglifh Spi¬ 
ders ; but they lay Side by Side, with their 
Points bending downwards, and in Readinels 
to ilrike either fingly or together, after the 
Manner of the Farantula. Thefe deadly 
Weapons of the Spider I was very induftri-? 
gus to examine, and by my Glades could 
difcern very diflindly a minute Opening or 
Slit near the Extremity of each Fang juft in 
the Front thereof, through which one can 
hardly doubt a poifonous Juice was ready 
(when the Creature was alive) to be ejeded 
into the Wounds it made. This Aperture is 
defcribed by Mr. Leeuwenhoek , in the ayzd
