With this series, the following results were obtained with a specific gravity bottle: Mixture. Temp. Fah- renheit. Specific grav- ity.

EXPERIMENTS WITH OIL OP RYE. § 11. A series of mixtures of the same 99.5 per cent, alcohol with oil ■ rye was made, in the same manner and proportions as those with :l of juniper. These mixtures gave the following results; Mixture. Temp. Fah- renheit. Specific grav- ity.
