Microfcopical Animals 5 by Mr. Steph. Gray. Phil. Trani^ 
N^ 221. p. 280. 
MR. Gray obferved in hemifpherules of water duly applied 
to the end of a wire, two forts of microfcopical inle6ls, glo- 
bular and elliptical. Thole of a globular form are but a little 
lefs tranfparcnt than the water they iwim in, they have fometimea 
two dark fpots diametrically oppofite, but thele are rarely leen ; 
there are fometimes two of thele globular infe6is ilicking together; 
where they were joined, it was opaque ; they have a two-fold 
motion, a I'wift progreflive irregular one, and at the lame time a 
rotation on their axes at right angles to the diameter that has the 
dark I'pot.s ; but this is leen only when they move flowly , they 
are almoll of an incredible minutenels. Mr. Gray examined 
many tranlparent fluids, as water, wine, brandy, vinegar, beer, 
fpitt'lc, urine, ^c. and he does not remember to have found any 
of them without more or lefs of the bodies of thele infects 5 but 
he did not obferve any motion except in common water, that has 
ftood for fometimes a longer, at other times a Ihorter time, as has 
been oblervcd by M. LeeiJOenhoecK tho' Mr. Gray does not re- 
member that he had oblerved that they exift in the water before 
they revive 3 in the river, after the water has been thickned by 
rain, there are infinite numbers of them, that the water feems in a 
great mealute to owe its opacity and whitenels to thole globules 5
