Table 1-Analyses of OilsTable3-Rapid Hydrolysis of Linseed Oil Emulsions Analyses were made when oils were first obtained and 44 mos. later, at the time they were used in repainting tests. The oils were again analyzed 22 mos. later in September, 1916. Chemical changes occurring in the oils are denoted by the constants.

The reddish filtrate upon cooling gave a large crop of reddish yellow needles which after twice recrystallizing from hot water gradually melted between 115 and 140'. 0.1659 g. subst. gave 0.4976 g.
