Alcohol, according to the analysis of Saussure, is composed of

And carbonic acid is composed of

Oxygen, 72*7 or 2 atoms.

Hence it is obvious, that sugar can be resolved into alcohol and carbonic acid only on the supposition that it contains three atoms of oxygen, three atoms of carbon, and three atoms of hydrogen ; proportions which do not accord with any of the analyses stated above. Supposing its composition to be so, the weight of each of the constituents per cent, is as follows :—

Hydrogen, 6*66

Oxygen, 53'31

Hydrogen, Carbon, . Oxygen,

. 13*70 or 3 atoms. . 51-98 or 2 atoms. . 34*32 or 1 atom.
