“…Howrever, his results certainly do not preclude chemical fogging of the plates. Benzaldehyde is known to produce the Russell Effect (37), and the benzaldehyde phenylhydrazone itself is readily oxidized by air (116). In his third experiment the black paper very possibly caused fogging.…”

“…One of the most sensitive, though unfortunately not a specific test for volatile peroxides, is the formation of latent images when they act on photographic plates (13). The action of hydrogen peroxide on a plate is similar in every respect to that of light (21).…”

possible with the various solvents now available, but it is probable that few, if any, are true constant-evaporating mixtures. The behavior of a mixture of benzene, butyl acetate, and amyl alcohol has been referred to by Hofmann and Reíd (9). The ingredients are removed from the mixture by evaporation, more or less completely, in the order named, although of course all are evaporating simultaneously at different rates. Summary 1. Evaporation rates of organic liquids are not proportional to their boiling points.2. Determinations of rates of evaporation by the usual method are sufficiently indicative for practical purposes, but the results are not capable of numerical expression.3. For pure liquids the slopes of the evaporation curves may be used to express the rate of evaporation. 4. A simple method of determining rates of evaporation of pure liquids is described. In this method temperature, humidity, and air velocity are controlled, and the apparatus is preferably calibrated with a standard liquid. (Normal butyl acetate was used.) 5. The rate of evaporation of a liquid may be approximately predicted by means of the formula: vapor pressure X mol. wt. -s-11 which gives a rate of 100 for n-butyl acetate (20°C.).6. The compositions of several new binary constantevaporating mixtures and of two ternary mixtures which may be called "apparent constant-evaporating mixtures," have been determined.
