2. British Association. — The sixty-eighth meeting of the 

 British Association for the Advancement of Science was held at 

 Bristol from September 7 to 14 : this is the third time the city- 

 has been thus honored. The meeting was thoroughly success- 

 ful both in scientific results and in attendance, as recorded in the 

 issues of Nature for Sept. 8 and following dates. The inaugural 

 address, delivered by the President, Sir William Crookes, was 

 largely devoted to a discussion of the probable food supply avail- 

 able in the future for the increasing population of the earth. 

 After showing "that England and all civilized countries stand 

 in deadly peril of not having enough to eat," the speaker indi- 

 cated that some comfort could be found in various directions, 

 particularly in the probable solution of the problem of obtaining 

 nitrates for enriching exhausted soils from atmospheric nitrogen 

 by electrical means. The address also included an interesting 

 account of recent progress in the departments of physics and 

 chemistry, to which the speaker had especially devoted himself.
