T ilE flalks of a large nofegay of blue-bottles with 
fome of the flowers, were put into cold water on 
the fecond day of June, and at the fame time fome of the 
flowers by themfelves were put into a glafs of water j in, 
twelve hours time the microfcope difcovered feveral ani¬ 
malcules of the form of fig. 235. in a fmall drop of this 
liquor. And the next evening four other forts, very 
tranfparent, of an oval figure, unequal in fize, and dif¬ 
ferent in their motion. The fifth of the fame month, 
another fort of the fhape of fig. 236. appeared therein ; 
and on the fixth a new fort, ABC, Fig. 237. with an 
©val head and a tail, which terminated in a point, being 
five or fix times longer than its body. On the feventh 
day, one of thefe laft was obferved to drag after it a 
bunch of the fediment of the infuflon, which funk to the 
bottom of the concave, upon which the drop of liquor 
was placed for obfervation. It is very pleafimt to behold 
fa fmall an animal endeavouring to pull this bunch about, 
which he, is fcarce able to move, as at I, drawing him- 
feIf back, and wriggling its tail, as at M. Sometimes 
five or fix of thefe animalcules may be feen fattened by 
She tail, to a great bunch of this fediment, that flicks to 
the bottom of the object carrying glafs, drawing them- 
felves nearer to, and retiring farther from it by turns. 
During this exercife, they change their firfl figure, and 
recover it again alternately i and as their tail is naturally 
jftrait, as at I, they endeavour to drag the lump after
