Abstract
THIS little book of 41 pages is specially written as a laboratory guide to the methods of determining molecular weights from observations of the freezing-point and boiling-point of solutions made by means of the Beckmann pieces of apparatus. It contains short historical accounts of the theory of the two methods, and descriptions of the apparatus, including the latest modifications, and the modes of making the observations. Lists of data for calculating results when using different solvents, and numerous examples of the kind of values obtained, taken from Beckmann's papers, are also included. The author is careful to direct attention to the anomalies likely to be met with, and has succeeded in writing a trustworthy account of the present condition of these two widely used methods.
