Mannane as an article of human food, C. Tsuji {College Agr.^ 

 Tolii/o, Japan, Bui., vol. 72, Xo. 2, pp. 103-105). — There are sold in Japan 

 as food gelatinous colorless tablets made from the tuberous rootstocks 

 of Amorphophallus rivieri durien, a plant belonging to the Aroidew^wCi 

 largely cultivated in Japan. These tablets appear to consist of starch 

 paste, but do not give any reaction with iodin, and the author's investi- 

 gations indicate that they are composed of mannane, a polyanhydrid of 

 raannose. The dried ground rootstock yielded 55.80 per cent of man- 

 nose. All attempts to convert the mannose of this powder into a sugar 

 by diastase were unsuccessful.
