Experiment XCIV. 
I placed fowls under glafs veflels filled 
fometimes with inflammable air, and at 
others with vitiated, or with phlogiflicated 
air. The Ihocks which I obtained by the 
ordinary procefs were extremely weak, 
and only took place at long intervals from 
each other, and were not able to bring 
them to life. In thefe animals there is not 
any obfervable difference the mufcles to 
which one could attribute this want of 
energy. I have never in thefe inftances 
made ufe of artificial electricity, but T 
believe it would prove ineffectual. This 
agent is not a remedy for every fpecies of 
afphyxia, on the contrary, in many of them 
it may prove very dangerous ; but without 
dwelling longer upon this fubjeCt, let me 
endeavour to lay before my readers fome 
new faCts.
