Abstract
THE new volume of this journal opens with a report of the May lecture delivered by Prof. Soddy dealing with the subject of radio-activity. The remainder consists of the papers read at the Sheffield meeting of the institute. Of these the most discussed was one by Dr. Hatfield and Capt. Thirkell on season-cracking, in which a different view is taken from that recently put forward by Rosenhain and Archbutt, and experiments are made to determine the intensity of the internal stress in the case of cold-worked brass. The conclusion is drawn that such stresses approach very closely to the maximum stress which the material is capable of resisting. The mercury salt method has been found very useful for revealing the presence of internal stress. Some very remarkable alloys are described by Dr. Stead. Alloys of tin, antimony, and arsenic, within certain limits of composition, have the habit of forming spherical segments of striking regularity. Dr. L. J. Spencer gives a summary of the information as to the occurrence of strongly curved crystals in minerals, but no satisfactory explanation has yet been given of the conditions underwhich such curved growth takes place.
