WE learn with great regret that it has been found necessary to postpone the festivities arranged to take place at Leyden to-day (November 3). On this date Prof, van Bemmelen completes his eightieth year, and he was to have received the personal congratulations of friends and disciples from all parts of the world. Owing to his illness, the ceremony is to be cpnfined to the formal presentation of the jubilee volume by Prof. Lorentz, if, as is hoped, Prof. van Bem-melen is sufficiently recovered to receive him. The jubilee volume is a remarkable testimony to the regard which is felt throughout the world for the distinguished second founder of colloidal chemistry. It contains a portrait, together with a biography and a bibliography of the professor's published works. Sixty papers on subjects connected with the colloidal state have been contributed by workers from all parts of the world. Amongst the authors are le Chatelier, Duhem, Zsigmondy, Liesegang, von Wiemarn, Hissink, Freundlich, Biltz, Spring, Hardy, Svedbprg, Jordis, Wolf. Ostwald, Loitermoseri Nietzk, Spiro, Bechold, Tamman, Barus, Bredig, Lorenz, Malfitano, &c. The volume is published by C. de Boer, Helder, Holland.
