wheels moving from the point D, which we will call the Weft, and 

 carried round, with a very fwift motion, by the South towards the 

 point E, which we will call the Eaft. 



When one of thefe Animalcules is creeping along the glafs, it 

 affumes the figure H I K L M N O, fg. 34 : the parts, H and M, 

 being alternately fixed to the glafs, and in this lltuation the organs, 

 like wheels, which in the former figure are ftiewn between D and 

 E, are drawn within the body, and a part like an horn, marked L, 

 appears in fight. Befides thefe pofitions, the animal twifts and 

 turns its body into fuch wonderful Ihapes, that I have often been 

 afl:oniftied to behold it. 



The limner alfo faw feveral Animalcules of a fliape fimilar to 

 what is reprefented at fig. 35, P Q ; thefe had the lower parts of 

 their bodies of a flat fliape, from which iflued various minute or- 

 gans, which they ufed in moving themfelves from place to place. 

 Now in the body of this Animalcule, were many globular particles, 

 and in the fame water were many ftill fmaller Animalcules, whofe 

 whole bodies appeared no larger through the microfcope than one 

 of thofe globules in the former Animalcule. 



I have often placed the Animalcules I have before defcribed out 

 of the water, not leaving the quantity of a grain of fand adjoining 

 to them, in order to fee whether, when all the water about them 

 was evaporated and they were expofed to the air, their bodies would 

 burft, as I had often feen in other Animalcules. But now I found 

 that when almoll all the water was evaporated, fo that the creature 

 could no longer be covered with water, nor move itfelf as ufual, 

 it then contracted itfelf into an oval figure, and in that fiiate it re- 

 mained, nor could I perceive that the moifl:ure evaporated from its 

 body, for it preferved its oval and round fhape unhurt. 



In order more fully to fatisfy myfelf in this refpeCi, on the third 

 of September, about ieven in the morning, I took fome of tiiis dry 

 fediment, which 1 had taken out of the leaden gutter and had llood 

 almoft two days in my lludy, and put a little of it into two feparate
