certain of finding them therein •*, and, if 
In Summer, when all the Water is dried 
away, and nothing but Dull remains, that 
Duft appears red, or of a dark brown, one 
ihall feldom fail, on putting it into Water, to 
difcover Multitudes of minute reddifh Glo¬ 
bules, which are indeed the Animals, and 
will foon change their Appearance, in the 
Manner juft now mentioned. 
The Minutenefs of thefe Animals makes 
it almoft impofiible to know whether you 
have them in the Water of not, without ex¬ 
amining it by Glafles : the fame Minutenefs 
renders it alfo impracticable to feparate them 
from the Dirt or Slime found along with 
them* and on which perhaps they feed : in' 
fhort, they are intifely microfcopital Life Els, 
and whatever is faid concerning them muft 
be underftood to imply, as under InfpeCtion 
iby the ftrft or fecond Magnifier of the Dou¬ 
ble Microfcope. 
My Way of difcovering them is by plac¬

feonhderable Time even in the Houfe : for I have often met 
with them, in fufficient Plenty, in a Sort of flimy Matter* 
_ that is apt to be produced on the Sides of Glaffes and other 
Veifelsj that are kept long with the Infufons of Hay or other 
Vegetables ; and probably they are wafted thither by the Air* 
when in the Condition of little dry Globules*
