I. ANIMALCULA OF INFUSIONS, 12^ 



" two on the point of feparation, and exerting 

 " themfelves to attain it, they precipitate them- 

 '* felves between them as if to affift in break- 

 *' ing the connedljng hgament. Nor con we 

 " view thjs ja£l as only fortuitous, fmce they are 

 " generally careful to avoid one another, and 

 " never ftrike together whatever ti e rapidity of 

 " their courfe may be. 



" Another fpecies, fouiid in hempfeed infu- 

 " fions, wich a beak or hook before, alfo multi- 

 *' ply by divifion, but in a more fmgular man- 

 " ner. When going to divide, the animalcule 

 '* feeks a convenient place at the bottom c the 

 " infufion, commonly that femi-tranlparent kind 

 " of mucilage which forms in hemp mfufions. 

 " After fearching and examining various places, 

 " it at laft fixes on one. The body, which is 

 *' naturally long, contracts, the curved beak is 

 " retraced or concealed, and the animal af- 

 " fumes a fpherical form : it next infenfibly be- 

 '* gins to revolve on itfelf, fo that the centre of 

 " motion is fixed, and the fphere never changes 

 ** its place. The motion is performed with the 

 " mod perfe6t regularity, but the direftion of 

 " rotation is confhantly changing, fo that the ro- 

 " tation may be firll from right to left, then 

 " from before, and next from left to right. And 

 *' all thefe changes are imperceptibly performed, 

 '* without the animalcule or rotatory machine
