Professor Patrick Geddes, of University College, Dundee, 

 delivered an address on a plan for increasing the educational 

 value of expositions, in which he traced the increasingly com- 

 plex relation of the world to science and the rapidly increas- 

 ing need of co-ordination of the sciences, and then gave a 

 concise account of the purposes which it is hoped to realize 

 and the methods to be adopted by the International Associa- 

 tion for the Advancement of Science, Art, and Education, 

 which grew out of the meetings of the British and French 

 Associations for the Advancement of Science last autumn, and 

 which is to hold its first international assembly at the Paris 

 Exposition in the course of the present year, the purpose of 

 the Association, — recognizing the wealth of instructive

 that city, and the thoroughness with which the streets, court 

 yards and cesspools were cleansed by the Engineer Corps, 

 which also charged itself with the betterment of the city water 

 supply. A diagram which the speaker had prepared showed 

 that in addition to a very marked lowering of the death rate 

 which attended the supply of an abundance of wholesome 

 food, on the occupation of Cienfuegos, there had been a 

 decrease of considerably over fifty per cent, in the weekly death 

 rate, directly attributable to the sanitary cleansing of the city ; 

 and he further stated that since this work had been done,
