THE CONSTITUTION AND FUNDAMENTAL PROPERTIES OF
SOLIDS AND LIQUIDS.
The importance of the work of W. H. Bragg and W.
I,. Bragg in its
bearing on chemistry has not, as yet, been generally recognized. In
hearing two of W. H. Bragg's lectures in this country a few years ago, the
writer was impressed with the very great significance of this work in the
field of chemistry. The structure of crystals as found by the Braggs
leads to new and more definite conceptions as to the nature of chemical
The writer has constantly endeavored to apply this new conception
in his work on heterogeneous reactions and particularly in connection with
a study of the phenomena of adsorption and surface tension. In this way
he has gradually been led to form more or less definite theories of the
mechanism of evaporation, condensation, liquefaction, adsorption, and
capillary phenomena. According to this theory, both solids and liquids
