162 ANIMALS KILLED Bef’ 
curved claws of feveral infects. The corpulence 
of the floth, rendering it opaque, prevents us from 
feeing the internal organization. But we can 
perceive a {mall elliptical fpot in the middle of 
the “body, which I fufpe& to be the refervoir of 
the aliments. In the anterior part is alfo diftin- 
guifhed an internal lucid fpot, fmaller, narrower, 
and longer than the other, which I have fometimes 
iuppofed the cefophagus. The figure of the 
whole is clumfy, and very much refembles the 
tefticle of a cock. The floth is reprefented fu- 
pine, fig. 7. pl. 3. the profile is feen fig. 8. 
This animalcule forms no vortex in the wa- 
ter, which is not furprifing, as it has. neither the 
wheels nor fibrillae of the animals that perform 
this operation. It appears that the wheel animal 
cannot advance a ftep without fixing the trident to 
fome adjacent fubftance ; it is otherwife with the 
floth, for it often makes no ufe of its hooked fila- 
ments. It never fwims ; it is {pecifically heavier 
than the water; thence it always turns round on 
the furface of the fand, or amoneft it. 
The phenomena of its death, from the want of 
water, and of refurreCction when water is fupplied, 
are precifely the fame with thofe of the wheel 
animal. Motion gradually ceafes: the limbs 
are contratted and drawn entirely within the bo- 
dy, which diminifhes very much, is completely 
dried, and aflumes a globular figure, pl. 4. fig.
