An Introduction to Theoretical and Applied Colloid Chemistry: “The World of Neglected Dimensions” The Chemistry of Colloids

Abstract

AFTER reading the books the titles of which stand at the head of this article, one is inclined to ask whether the word “colloid” as it has come to be used does refer to a definable state of matter, or whether it is not, in fact, used as a convenient label for a heterogeneous group of states which have only this in common, that they are not easily assimilated to the ordinary doctrines of molecular physics.
