Extract

The phenomena attending the absorption of oxygen by soils have been investigated by Déherain and Demoussy, and also by Wollny. An account of the work of the French chemists can be found in the Annales Agronomiques. Their method was to place the soils under examination in a closed tube holding about 100 c.c. and kept at constant temperature, then after a certain time to extract the gases and determine the carbon dioxide present. This was taken to be a measure of the amount of oxidation. The general results they obtained are as follows:

1. The quantity of carbon dioxide produced increases with the temperature to about 65°C., and then decreases. At higher temperatures (above 90°) it increases again.
