Briefs Kinetic Study of the Stabilities of Chloromethyl Methyl Ether and Bis(Chloromethyl) Ether in Humid Air The rates of hydrolysis of chlormethyl methyl ether and bis-(chloromethyl)ether in the gas phase are found to be proportional to the water concentration and the hydrolysis is highly surface catalyzed.

Warren, Natural Products Research Laboratory, University of Cape Town, Rondebosch 7700, Cape, South Africa Anal. Chem. 46, 1870 (1974)

Evaluation of an Ozone Photometer for Ambient Ozone Measurements Model 1003A Ozone Photometer is found to be accurate to ±0.02 ppm with a linearity of 1.016 ± 0.017. Airborne oper­ ation of this instrument is satisfactory and no interferences are found. Leo Zafonte, William Long, and James N.
