petly reprefented, that an intolerable flench arofe from 
the dog; and that an afliftant dropped down fenfelefs 
upon going into the ftove. 
To prove that there was no fallacy in the degree of 
heat fliewn by the thermometer, but that the air which 
we breathed was capable of producing all the well-known 
effedls of fuch an heat on inanimate matter, we put fome 
eggs and a beef-fteak upon a tin frame, placed near the 
ftandard thermometer, and farther diftant from the cockle 
than from the wall of the room. In about twenty mi- 
nutes the eggs were taken out, roafted quite hard ; and 
in forty-feven minutes the fteak was not only drefled, , 
but almoft dry. Another beef-fteak was rather over- 
done in thirty-three minutes. In the evening, when the 
heat was ftill greater, we laid a third beef-fleak in the 
fame place: and as it had now been obferved, that the 
effecT of the heated air was much increafed by putting it 
in motion, we blew upon the fteak with a pair of bel- 
lows, which produced a viftble change on its furface,, 
and feemed to haften the drefling; -the greateft part of it . 
was found pretty well done in thirteen minutes. . 
About the middle of the day two ftmilar earthen vef- - 
fels ; one containing pure water, and the other an equal 
quantity of the fame water with a bit of wax, were put’ 
upon a piece of wood in the heated room.. In one hour ' 
and an half the pure water was heated to 140° of the 
thermometer, whilft that with the wax had acquired an ' 
heat of 1 5 2°, part of the wax having melted and formed - 
a film on , the, fur face of the water, which prevented the : 
evaporation :
