— Among recent deaths, we note those of Mr. G.

— The ethnological sub-commitee at Berlin has 

 again engaged Capt. J. A. Jacobson for a long expe- 

 dition through Russia and Siberia, and also through 

 the Amur region to the Pacific coast. Capt. Jacob- 

 son, who only a few months ago returned from a two 

 and a half years' journey through Alaska and north- 

 west America, whence he brought a collection of eight 

 thousand objects, will start very soon. After he has 

 made this journey, he intends to go to British Colum- 

 bia, and enter again the service of the animal-mer- 

 chant, Carl Hagenbeck, at Hamburg, for whom he 

 has made several journeys before, through Lapland, 

 Greenland, and Labrador. 



— The annual meeting of the Entomological club 

 of the American association for the advancement of 

 science will be held in a parlor of Hotel Lafayette, 

 Philadelphia, commencing at two p.m., Wednesday, 

 Sept. 3. In accordance with the rules of the club, 

 the meeting is called the day before the opening of 

 the general meeting of the association. Entomolo- 

 gists who desire to read communications are re- 

 quested to notify, as early as Aug. 15, either Dr. D. 

 S. Kellicott, president, Buffalo, N.Y., or Mr. O. S. 

 Westcott, secretary, Maywood, 111. 



— To increase the interest in the work of the 

 chemical section of the American association, the 

 chairman of the section, Prof. J. W. Langley of Ann 

 Arbor, has suggested that one or more subjects be 

 brought up for special discussion, and, with the hope 

 that others may be suggested by the members, has 

 issued a circular, in which he puts forward the 

 following as probably offering good opportunity for 

 debate: 1°. To what extent is the hypothesis of 'va- 

 lence,' or ' atomicity,' of value in explaining chemi- 

 cal reactions ? 2°. W T hat is the best initiatory course 

 of work for students entering upon laboratory prac- 

 tice ? 3°. What is the best method for determining 

 phosphoric acid ? 4°. To what extent is the ' influ- 

 ence of mass ' of practical importance in analytical 

 operations ? If the choice of a majority of the sec- 

 tion falls on one or two topics, Professor Langley will 

 have the titles put upon the Philadelphia announce- 

 ments. 



— As an improvement of the meteorological ser- 

 vice on the coast of eastern Asia, a meteorological and 

 astronomical station has been established at Hong- 

 Kong, on the peninsula Kaulun, opposite the city. 

 Hitherto the observatory at Manila warned the port 

 of Hong-Kong when a typhoon approached.
