Abstract
1. Organic acids when treated with H(2)O(2) and Fe(2)(SO(4))(3) produce CO(2) at a rate that can be measured by the indicator method. 2. In the case of acids containing a double bond, the rate of production of CO(2) can be varied by the addition of an anesthetic. The changes in the rate of production of CO(2) under the influence of a typical anesthetic, such as chloroform, show a striking resemblance to the reaction of the organism.
