the asli and protein content of this residue there would remain the 

 nitrogen -free material insoluble in the above-named solvents. The 

 method as suggested is simpler and easier of manipulation than that 

 suggested by Konig. 3 — J. p. street. 



Report of the chemist, R. C. Kedzie (Michigan Sta. Bpt. 1896, pp. 128-131).— A 

 general summary of the work of the chemical department during 1896, including 

 more detailed notes on the ash of epiphytes (noted elsewhere) and the dauger result- 

 ing from the use of Paris green against insects on peppermint. A chemical exami- 

 nation of the oil distilled from peppermint plants sprayed with Paris green gave 

 distinct reactions for arsenic.

Contribution to the study of the albuminoids of flour of legumes and cereals, 

 E. Flei-rent (Compt. Bend. Acad. Sci. Paris, 126 (1898), No. 19, pp. 1374-1377).— 

 According to the author, bean flour contains 31.04 per cent total nitrogenous mate- 

 rial, made up of 18.92 per cent legumin, 0.2 per cent albumin, and 11.92 per cent 

 gluten. The gluten consists of 9. 52 per cent glutenin and 2.40 gliadin. The so-called 

 vegetable casein is regarded as legumin and glutenin and vegetable fibrin as albumin 

 and gliadin. The properties of nitrogenous constituents are briefly discussed, as 

 well as the use of bean flour with wheat flour for bread making.
