Abstract

THE list of books at the head of this notice suggests some reflections. Of the six, only one is published in England, while among the four published in the United States there is a volume of nearly 400 pages containing the papers presented at the fifth National Symposium on Colloid Chemistry. The symposium is now an annual institution, while the last general discussion on colloids, arranged jointly by the Faraday Society and the Physical Society of London, took place in 1920. Since then there has been a gradual cessation of all organised activity, and even the publication of the British Association reports on the subject, which met an obvious want, has been discontinued. This is not the place for inquiring into the reasons for this curious neglect of a discipline, the foundations of which were laid by Graham, Linder and Picton, and Hardy, but the opportunity of directing attention to it could not be lost.
