*34 Of Anlmalcula in Fluids, 
the difcovery of two new forts of animalcula, and this in 
the leaft drop that could be applied to the microfcope, D, 
and EF, fig. 217. are their reprefentatives. The largeft 
of them refembles the filver bag-pipe, each having crooked 
heads, as at F 3 they have alfo two motions, one ftrait, 
and the other circular, flow enough to be eafily ob- 
ferved. 
Another kind of fifli-like animulcula refembling a carp, 
is fihewn at fig. 218. its motion was wriggling as the dotted

In January a great number of another fort were found' 
in this infufion of Senna, which ballance themfelves from 
right to left as they fwim diredlly forwards. Another 
time, after replenifhing the water, other minute animal¬ 
cules that do not ballance themfelves were found therein, 
and the fame day others alfo fo exceeding finall that their 
form could not be difeerned. A few days another fort

After this infufion had flood a whole year, another worm¬ 
like animalcule was found therein, reprefented at fig. 220. 
whereof A was its mouth, which was round; from 
whence ifiued three fibres to its forked tail B B, two 
other forts, as reprefented by K L, fig. 121. were alfe 
feen in this infufion. 
Of the water found in oyfters. 
A Dozen of oyfters being opened, all their liquor was 
put in a clean drinking glafs, which in the fpace 
of two hours appeared to be upon the fret, and of a fine 
pearl colour, and its fmell like that of the fea 3 on ap¬ 
plying fome of this liquor to the microfcope after it had 
flood four days, a great number of minute tranfparent
