α‐Chloronaphthalene plus 30 weight percent of dimethylphthalate was the solvent with 0.5% ethyl cellulose as stabilizer. A polymer concentration of 0.0025% gave optimum results. A parameter S which is defined as the difference in temperature between 20% and 50% of the total reduction in phototube output is related linearly to a parameter of the Wesslau distribution.
