wivacious as before. Urine, falt water, and vinegar, 
produce fimilar effeéts, though fatal in other cir- 
cumftances, as we fhall fee. When dry during 
fome days, they require.a full hour for revival. If 
one has patience to wet them, and allow them to 
dry, death and refurrection will be feen in an im- 
portant limitation: which is, the oftener humec- 
tation is repeated, the lefs the number of refur- 
gents will be, and the longer time required for 
revival. I had a number of lively eels in a watch- 
glafs, the firft time they were revived : one thou- 
fandth part did not revive the eleventh time, and 
the feventeenth there was not ene. I have often 
repeated this important fat, and always with the 
fame confequence, except that the reviving eels 
either went beyond the feventeenth time, or died 
before attaining it. Not only wheel animals, 
floths, and the minute eels of roofs, but alfo thofe 
of blighted corn, enjoy the property of refurrec- 
tion circumfcribed within certain limits, beyond 
which it is loft. The body to revive muft be en- 
tire. Eels, cut into two or more parts, though 
often wet, and remaining long in water, never ex- 
hibit any fign of motion. All fenfation is loft on 
divifion in two, after a flight univerfal vibration 
or convulfion of the body. 
I have fubjected the eels, as well as wheel ani- 
mals, to different experiments, and firft to elec- 
tricity, ufing Franklin’s battery. Thofe alive
