10 mm. was saponified. The calculated percentage of acetic acid is 72.31; that found was 71.70. The mannide was prepared by the method devised by Liebermann (8). Analysis gave: C, 48.37 per cent; H, 7.32 per cent.The calculated values are: C, 49.27 per cent; , 6.90 per cent. The isomannide was prepared by Fauconnier's method (9). The compound melted sharply at 87°C. (uncorrected).The dulcitol employed was Pfanstiehl's c.p. product, m.p. 188°C., free from galactose. The dulcitan was prepared by Berthelot's method (10).Analysis gave the following composition: C, 43.79 per cent; , 7.20 per cent. The calculated values are: C, 43.87 per cent; H, 7.37 per cent.
