From these series of values appears in any case the peculiarity 

 that the curve of the moduli of expansion of mixtures of alcohol 

 and water exhibits a maximum at a concentration of about 80 7o> 

 and a point of inflection at about 20 Ve- 

 in conclusion we subjoin an extract of the table of the sp. gr. ^ 

 (1.1.) for 7o (vol.), as they have been given by von Baumhauer in 

 comparison with the better values, confirmed by us of the B. of S. 

 at Washington, rounded off to the fourth decimal. 



to the concentration of our mixtures; those of Mendelejeff have besides been 

 recalculated with respect to the better spec. gr. of water and to tlie intern, 

 hydrogen scale.
