Solubility isotherms in the title system were measured at 0, 25, 50, and 70 °C. Regression straight line equations interrelating the solubilities of boric acid and glycine were derived. The activity of water in saturated solutions of the system at 25 °C was determined by vapour pressure measurements.

Introduction . —In the course of some work, communicated to the Royal Societ by one of us, in which determinations of the boiling points of some saturated solutions were made by Buchanan’s method (the so-called Landsberger-Sakurai method), it was pointed out that these boiling points probably varied according to the height of liquid operated upon. During the course of that research a few experiments, which, however, are not recorded in the paper, were made on the boiling point of water; and it was found that this boiling point was approximately that due to a head of water equal to half the total height of liquid. The paper cited mentioned the hope that direct osmotic pressure measurements might be obtained; this hope has not been fulfilled, but as an exact connection between the vapour-pressure and the osmotic pressure of a solution has since been worked out, a knowledge of the boiling points will enable the osmotic pressure to be calculated.

Experimental Values

1. The construction, maintenance and calibration of a sensitive instrument capable of making numerous vapour-pressure measurements within humidity gradients by the dew-point method is described. 2. Coefficients of diffusion of water vapour in air, calculated from observed vapour-pressure gradients and measured rates of evaporation agree with theoretical and other experimental values in still air. 3. Apparent coefficients in wind speeds between 10 and 100 cm/s were significantly lower than those in still air. 4. This finding, together with the performance of the dew-point probe, is discussed in relation to its possible use in the study of evaporation from animals and plants.
