and by the help of thefe tails the Animalcules fixed theinfclves to 

 the giafs ; the lefler of thefe appeared to me to be the offspring of 

 the larger ones. 



Moreover, I faw another kind of Animalcules much fmaller, the 

 bodies of them were very tranfparent ; but there feemed to be an 

 hundred of the former fpecies to one of them. 



On the 3 111 of Augull, the M'ater which I had before obferved, 

 was, by three fucceffive days of hot weather, fo dried away, 

 that when I prefled my finger on the muddy fcdiment in the gut- 

 ter, no more water than about the fize of a grain of fand adhered 

 to my finger, in which water I difcovered a fmall number of tranf- 

 parent living Animalcules, but all the green and red ones were

The fir/l of September the fcdiment in this leaden gutter was fo

 could fallen themfelves to the glafs, and the fore part of their bo- 

 dies being alio provided with certain organs, when they would move 

 from place to place, they brought their hind parts nearer to th« 

 fore part, and then, loofing the fore part, they extended it in like 

 manner as we fee caterpillars do ; and, in fwimmiug, they made ufe 

 of other organs defiiined for that purpofe. Soon afterwards I ob- 

 fcrvcd many of the fame fpecies of Animalcules. 



The matter in the bowels of thefe creatures was for the raoft part 

 red, proceeding (as I imagine) from their feeding on fmaller Ani-
