This minute animalcula is frequent in stagnant water, or in 

 infufions of vegetables, and is one fpecies of thofe whofe exiftence 

 can only be difcovered by a good microfcope. It is very difficult,

 at pleafure, to fix their diflinguifhing character : therefore where the 

 definition appears dubious, we prefer being filent rather than hazard 

 an error.

 whirl in the water feparately, with great fwiftnefs, devouring the 

 (mailer kinds of animalculae.
