SPECIFIC GRAVITY OF AQUEOUS ETHYL ALCOHOL. 



(a) The numbers here tabulated are the specific gravities at 60° F., in terms of water at the same tempera- 

 ture, of water containing tlie percentages by weight of alcohol of specific gravity .7938, with reference to the 

 same temperatures.*

(V) The following are the values adopted by the " Kaiserlichen Normal-Aichungs Kommission." They are 

 based on Mendelejeff's formula, t and are for alcohol of specific gravity .79425, at 15 -■ C, in terms of water 

 at 15° C. ; temperatures measured by the hydrogen thermometer.

(c) The following values have the same authority as the last ; the percentage of alcohol being given by volume 

 instead of by weight, and the temperature 15^.56 C. on the mercury in i'huringian glass thermometer; the 

 specific gravity of the absolute alcohol being .79391.
