hydrogen, charcoal absorbs 128 times more oxygen than hydrogen 
by weight. Now this ates is exactly equal to the density 
of oxygen squared and divided by two, _ , or it is half the pro- 
duct of the density of this gas and its atomic weight. Again, the 
most probable value for ni arog is 4°66 volu sages oe ~. 
hence the weight absorbed is 14 4°66 or 65 This number i

is simply 227. The carbonous oxide absorbed is 6 volumes, the
