94 Animalcules in Waters . '* 
ture) fcattered about the Water. There Is 
alfo a'third Sort, as beautiful as the forego¬ 
ing, but not near fo large; its Shape more 
refembles a Shrimp, and it carries its Spawn 
as the Shrimp does. Thefe three Species of 
Animalcules appear to have only one Eye, 
and that placed in the Middle of the Fore¬ 
head, without fo much as the lead: Trace of 
even a dividing Line. They are often to be 
found fo tranfparent, that the Motion of 
their Bowels is feen diftinCtly by the Micro ~ 
/cope , together with a regular Pulfation in a 
little Part, which therefore we may fuppofe 
to be the Heart. 
I fhall finifh this Head with defcribing 
a very wonderful Kind of minute Animal y 
the extraordinary Form whereof (about 
thrice the Bignefs it appeared to the naked 
Eye) whilil in the Water, and faftened to 
the Root of a Weed, is given Fig. III. This 
was a large one of the Sort, and had eight 
Horns ; whereas the fmaller ones have fel- 
dom more than fix. It is like wife fhewn 
here as extended to its full Length, but 
when contracted is not a fourth Part fo long. 
It fixes by the Tail to the P.oots or Stalks of 
Water-Plants. On the upper Side a very 
fmall Animalcule (a) is reprefented coming 
out of the other’s Body, This was fuppof- 
ed at firfl to have fattened' itfelf there by 
feme Accident; but, by obferving it nar¬ 
rowly.
