Different Wheel Animals. 293 
Water taken out of a Leaden Ciftern that 
flood in Somerfet Garden.— The anterior 
Part in the firft of thefe has a large Opening, 
furrounded with fharp Spiculce, a . and is evi¬ 
dently cruftaceous, though the Body and 
Tail are mufcular. It is not eafy to difcern 
the Inftruments within this Mouth or Open¬ 
ing that ferve to form a Current of Water, 
as the Creature does not thru ft them beyond 
the Neck b. When it fwims along it feems 
extremely formidable to the minuter Ani¬ 
malcules, Multitudes of which are frequent¬ 
ly fucked in, together with a great deal of 
Water, which is fpouted out again immedi¬ 
ately. When the Tail is faftened to fome- 
thing, it turns the Body about and diredls its 
wideMouth toevery Side, and bringsaStream 
of Water from a conliderable Diftance. The 
Motions of the Bowels are diftindtly vifibje 
in this Animal ; and within feveral of them 
one may fee an opake oval Body c , which by 
its Size and Appearance I imagine to be an 
Egg; which if it is, it fignifies their Increafe 
to be much lefs than that of moil other mi¬ 
nute Animalcules; for I never obferved more 
than a fingle one in any of them; and in¬ 
deed I never found the Creatures themfelves 
in very great Number. They are fomewhat 
larger than the common Wheel Animal.
