Two or three Days after, he perceived fome 
white Fibres at the Extremity of the Knob % 
and on the fourth Day it lay extended at full 
Length, and appeared as in Fig. V. and he 
was then convinced, that what he imagined 
an Excrefcence, was in Reality a young 
Animalcule of the fame Species, iffuing.from 
the old one, and having fix Horns. Next 
Day he found it in the Water entirely fepa- 
rated, and about a third of its Parent’s Length. 
The Horns come out like Radii, not from 
the Extremity, but quite round a fmall Knob, 
which probably is the Head : they have a 
vermicular Motion, and can extend or con-*

The other End is fat, and by that it often 
fattened to the Bottom or Side of the Glafs 
wherein he kept it. It alfo contrads and 
dilates its Body, and can bring both Body 
and Horns into a fmall Compafs, as in 
Fig. VI. and Fig. VII. The Horns are per- 
fedly white, the Body yellowifh, and not 
eattly difcernible by the naked Eye ; being, 
when extended, no thicker than a large 
Horfe-Hair.
