Colloid Chemistry

Abstract

THAT increasing attention is being paid to the subject of colloid chemistry is becoming manifest in various directions. Already the subject has taken its place in the chemical instruction of some if not of all our universities, while the technological literature shows (though as yet to a rather limited extent) that the significance of colloidal behaviour is no longer overlooked in a number of technical operations. The subject is one of comparatively recent growth, for, although originating with Graham more than sixty years ago, its importance has begun to be realised only within the last twenty-five years.
