rotatory "^ motion. In fliort, there is no race 

 whatever which, on diligent examination, does not 

 exhibit motions pecuHar to itfelf. 



If to all this we join the artijfice evinced in 

 forming a vortiginous current to entrap their prey: 

 their ferocious purfuit of the fmaller animakula, 

 their indifference when the ftomach is full, and 

 greedinefs after them when hungry. If we con- 

 Uder all the qualities relative to their nature, mo- 

 tion, and properties, not fmgle and disjoined, but 

 collected and united in the fame fubjed, it is im- 

 poiFible not t© admit one of two things : either 

 that an infinity of beings recognifed by all the 

 world as real animals are not actually fo ; or, if 

 they are, fuch alfo mull be the beings found in 

 infufions. 



If we refume the ufual mode of analogy, 

 which is the only fupport of accurate judgment^ 

 whether a fentient principle refides in animals ;, 

 and compare the various operations of infufion 

 animalcula with thole of the largeil animals and 

 ourfelves, we fhall not find them fo diflant or 

 different as not to correfpond in feveral particu- 

 lars. Befides the organization of many animal- 

 Gula being fo fimple as to appear nothing but an 

 aggregate of granuli invefted with a fkin, and 

 completely included in it : in fome we fee an af- 

 fembkige of parts for the moil oppofite ufes, fuch 

 are fibrilli for a vortex, fins for fwimming, a 



mouth.
