ascend in any series, it seems almost certain that there must 
be a point at which the increase in the boiling points will over- 
come the decrease in the vapor volumes, and therefore the 
amounts of vapor formed by the members of the series at their 
boiling points must begin to increase with every step upward. 
T have as yet found no such point, however, in any series upon 
which I have calculated.

vapor volumes are calculated from the specific gravities of 
liquids at 0°, while the atomic volumes are referred to the boil- 
ing points, and therefore an exact inverse ratio would be very 
improbable.
