I. ANIMALCULA OF INFUSIONS. I35 



cula are feen attached by the filament to minute 

 fragments in the infufion ; and they will divide 

 before the obferver. The number fixed by the 

 filaments is proportioned to the number of divi- 

 fions about to take place. 



The fame legumes produce another fpecies of 

 animalcula, alfo multiplying by longitudinal di- 

 vifion, and prefenting phenomena fimiiar except 

 in two fa6b : firjl^ The fibrilli are not in the ca- 

 vity, but on its lips ; fecondly. The figure refem- 

 bles a monopetalous flower. The body divides 

 exactly in two. 



There is alfo a fpecies confiderably larger, 

 which propagates by a little fragment detaching 

 itfelf obliquely from the body. This animalcule 

 is 'fometimes found in an infufion of beets. It is 

 fpherical, and has a filament which is not en- 

 dowed v/ith the lingular motions of the other 

 two fpecies, nor is the body fubjed to thofe mu- 

 tations of figure. The multiplication begins with 

 a fmall portion infenfibly detaching itfelf from 

 the body, near to the origin of the filam.ent, and 

 it is in continual motion, Plate i. fig. 4. H. 

 When feparated, it fwims actively through the 

 fhiid ; and although fmaller than one-twelfth of 

 the whole, it becomes equal to it in lefs than a 

 day. Then it begins to propagate in the fame 

 irianner.
