ANIMALCULA OF INFUSIONSdi 



From this it may feem, that although long 

 continued heat had not prevented the produQion 

 of anirhalcula, it had contributed to diminifh the 

 number, or alter the kind. But v/ith the reft of 

 the infufions it was otherwife : the kidney beans, 

 ■vetches, barley, and mallow feeds, were in a bet-

 third, globular. All three were incredibly nu- 

 merous. 



In the infufion boiled two hours, were animal- 

 cula of the largeft and fmalleft clafs, but few in 

 number ; ftill fewer, in that boiled an hour ; 

 and feweft of all, in that boiled half an hour. 



The infufion of mallows, boiled two. hours, 

 f)Toduced middle fized circular animalcula ; and

 In two infufions, boiled an hour, and an hour 

 and a half, the number and fpecies were the 

 fame : and though they might be furpa,ired by 

 thofe of the infufions boiled two hours, ftill they
