“…Even this procedure, in the authors' experience, may not entirely eliminate contaminating sugar-yielding substances, and it has, accordingly, seemed desirable to base the estimation of starch in plant tissues upon a more specific reaction for this substance-namely, the well-known color reaction with iodine. A procedure of this kind was described in 1895 by Dennstedt and Voigtlander (4), but was found unreliable by Littleton (S) and by Witte (17). Occasional references to the application of the iodine-starch reaction for quantitative purposes are to be found in the literature (9), but no satisfactory analytical development appears to have been made.1 2…”

this leakage was due to the method of mounting the gears, and the figures are much higher than would be found in practice. However, the relative figures show what may be expected with gears in poor mechanical condition.To the management of the Shell Oil Company, the author wishes to express his appreciation for permission to publish the data contained in this paper. These investigations were made possible by the cooperative efforts of several co-workers acting under the supervision of A. G. Marshall, assistant superintendent of the Martinez Refinery. The author is grateful not only to Mr. Marshall for his advice in carrying out these tests, but to other members of the Shell Oil Company Motor Laboratory staff:
