The oxygen evolved in six hours' time under the action of moderately strong sunlight has been calculated to be as much as would be absorbed by the process of respiration in twenty-four hours. The changes which carbon dioxide undergoes whilst in the wonderful vegetable laboratory are not thoroughly understood. We know that a large portion of its oxygen is separated from it, and... evolved in a pure state into the atmosphere. The influence of light in enabling plants to absorb and decompose carbon dioxide has been conclusively proved by numerous Amount of CO.^ beneficial to Plants. 25 1 experimenters, but by none more strikingly than by Boussingault.
