Animals may lofe their electricity in 
like manner as they lofe their heat ; I 
mean to allude to that electricity which 
animals accumulate, and condenfe in cer¬ 
tain organs, for the purpofe of making 
life of as they find occafion, and not to 
that electricity which is found in all bodies, 
independent of the principle of life. 
The aCtion of gas is different from that 
of poifon, as is evident from my experi¬ 
ments, as well as thofe made by other 
phyfiologifts, prior to the difeovery of 
Galvani. The aCtion of miafmata is 
likewife different from that of gas and 
poifon. The hiftory of difeafes will 
fumifh us with the mofl convincing 
proofs of this. In order to obtain 
fome faCts deduced from experiment, I 
endeavoured to excite gangrene in the in- 
teflines of animals, knowing how power¬ 
fully the miafmata arifing from this flate, 
aCt upon the vital principle.
