Contents of moisture, fat, protein, and eight minerals in commercial broiler breast and thigh meat were defined by analyzing ]5-bird lots in a factorial design of two sexes x two commercial strains x three widely separated regions of production. Small but statistically significant differences due to strain, sex, and region were found for many of the variables examined. Region significantly influenced all the element levels except phosphorus in both breast and thigh flesh. Calcium levels found were about half those previously reported. The differences are probably not nutritionally important under normal consumption patterns.

Summary A convenient method for the determination of monocarbonyl compounds in rancid foods is described. The quantitative procedure is based on the formation of the 2,4‐dinitrophenylhydrazones of monocarbonyl compounds in benzene solution, the removal of excess hydrazine reagent and the hydrazones of dicarbonyl compounds with alumina, and the colorimetric determination of the remaining hydrazones of monocarbonyl compounds in alkaline solution. Applicability to aldehydes varying in molecular size and degree of unsaturation has been demonstrated. The method may be used on the crude benzene extracts of rancid foods. Illustrative data are presented.

This was phenolic in nature and in an impure condition melted at 153-156°. It has now been determined that the same substance results from heating p-fluorophenol with benzene and aluminum chloride. When purified it melted at 163.5-164°and upon oxidation gave a high yield of benzoic acid. No depression of the melting point occurred when a sample of the unknown was mixed with p-hydroxybiphenyl. Hence A1C1, C6H6 + FC6H4OH--C6H6C6H4OH [ + HF]p-fluorophenol must react as shown and the phydroxybiphenyl obtained in the deethylation of p-fluorophenetole also results from this reaction.Attempts to extend the reaction in various directions have been without success.Because aromatic fluorine may be under some conditions replaced by chlorine,5 it seemed possible that pchlorophenol was an intermediate in the reaction.However, p-chlorophenol showed no activity toward benzene in the presence of aluminum chloride. None of the corresponding hydroxybiphenyl was isolated when p-fluorophenol and aluminum chloride were heated with toluene or chlorobenzene.By heating a mixture of 3 g. of p-fluorophenol, 7 ml. of benzene and 7 g. of aluminum chloride under reflux for two and one-half hours there was obtained about 1 g. of ^-hydroxybiphenyl, m. p. 164°. The 51 g. obtained in the deéthylation of p-fluorophenetole2 corresponds to 13% of the pfluorophenol reacting with the benzene.
