table Kingdom on the Animal Creation, By John Ingen-houfz, 
Counfellor to the Court , and Body Phyflcian to the Emperor y 
F. R. S, &c. 
Read June 1 3, 1782. 
U PON being informed, a few months ago, as well by 
private letters as from the Critical Review, that my 
doCtrine was quite over-turned by the fifth volume of Dr. 
Priestley, and by an experiment quoted in the book of 
Mr. cavallo on Air; I invited fome of my friends here to 
aflift at iome decilive experiments, of which I will here 
give an exaCt account. I told them the whole refult which 
was to be expected from them, if my fyftem was founded on 
nature, explaining to them before-hand the theory of thefe 
reiults, and promifing, at the lame time, that, if the refult 
fhould fail, I fhould myfelf be the firft to difcredit my own 
fyftem. I had the fatisfaCtion to convince them that the refult 
did lully anlwer my predi&ion and expectation. Thefe experi- 
ments are the following, all made in a hot houfe of the Bota- 
nical Garden in the winter of 1782. 
I expoled to the lun-fhine fix globular glafs veflels, each con- 
taining about 160 cubic inches of fpace, all filled with pump- 
water, which was boiled during more than two hours, and 
poured quite hot into the glafs veflels, on purpofe to prevent 
any accefs of air to the water.
