Vinegar had been expofed a whole Night to 
the fevered: Frofl, and was frozen, and thaw¬ 
ed, and frozen again, and fo feveral times 
over, they were as brifk as ever. He like- 
wife informs us, that in cold Weather he 
put fome Vinegar full of thefe Eels into a 
Glafs, and poured thereon about the fame 
Quantity of Oil, which floating on the Vine¬ 
gar, all the Eds would conftantly creep up 
into the Oil when the Vinegar began to 
freeze ; but upon thawing the Vinegar, they 
as condantly returned to it again. Thefe are 
pretty and curious Experiments. 
A Drop of Oil of Vitriol, mixed with the 
Vinegar, kills them in the fame Manner as 
Fire does. 
If fome Grains of Sand be put among 
the Eels before the Microfcope, it will be 
highly entertaining to fee them draggling 
and embarraffed, as it were, amongd large 
Stones.
