( 824 ) with a little preffing, I took a drop thereof , and in it difcover'd a mighty number of living Creatures. I repeat- ed my obfervation the fame eveaing with thefame fuccefs, but the next day I could find none ofthem alive^ and whereas I had laid that drop upon a fmall Copper Plate, f fancied to my felf that the exhalation of the moifture might be the caufe of their death, and not the cold wea- ther, which at that time was very moderate. In the beginningof Jpril I took the Male feed of a jack or Pike, but could difcover nothing more than in that of a Cod-fifh, but having added about four times as rauch Water in quantity as the matter itfelf was, and then making my remarks, I could perceive that the Ani- malcttU did not only wax ftronger and fwitter, but, to my great amazement, I faw them move with that celeri- ty, that I could compare it to nothing more than what we have feen with our naked Eye, a River Fith chafed by its powerf ul Enemy, which is juft ready to devour it : You muft obferve that this whote Courfe was not longer than the Diameter of a ungle Hair of ones Head. © VII.
