about the excrements wherein all the worms and eels were, which water I put 

 into a small glass tube, wherein were six eels, thinking to keep them alive, and 

 to observe whether they would breed any young ones. Yet I found the con- 

 trary, for they moved less, and within a few hours after some were quite 

 motionless ; and the next day I saw, after strict examination, only a part of an 

 eel. Hence I must conclude, that the eels were dissolved in the water. 



The frog had so moved about in the glass tube, that he had so separated the 

 first dung, that I saw almost a whole wing of a flying insect, about the size of a 

 gnat, and this was almost quite entire, so that I could see perfectly the great 

 number of small hairs which grew all over the outside, and also on the edge of 

 the wing. Underneath this wing I saw 3 of the said eels, and another in 

 another place, which had still a strong motion. On the 4th day after the 

 excrements were made, I saw some eels alive, as well above as under the wing ; 

 and as the moisture wherein thoy lay, was but very small, so was their motion 

 but little ; and afterwards I could perceive no motion at all. 



From these observations we may very well conclude, that the water was not 

 proper for these eels ; and that they either came out of the ground, or that the 

 animals the frog fed upon were loaded with them. On the 5th day the frog had 

 dunged again, and it lay oblong against the glass, without any moisture at all. 

 I took it out of the glass, and spread it abroad, because it was blacker to the eye 

 than the former, and saw that there were also parts of flying insects ; and among 

 this stuff" also lay several of the before- mentioned eels, but they were all dead, 

 and somewhat less than the former.
