glycerol escape,
A table in the appendix gives the specific
gravity of glycerol solutions in water. (It
is with the aid of some reliable table that the
strength of chemically pure glycerol is most
accurately determined. Of those published
the one by Gerlach is the moat accurate.)
The coeffecients of expansion of glycerine
vary with the different authors. lehner states
that it amounts to .00058° for each degree
centigrade in the neighborhood of 15,5*^ C,
According to Gerlach's observations the value
of the coeffecient varies with the temperatuuree
