T3E BRITISH ASSOCIATION FOR THE AD- 

 VANCEMENT OF SCIENCE'- 

 ADDRESS OF THE PRESIDENT 

 Thirty-one years have passed since the 

 British Association met in Sheffield, and 

 the interval has been marked by excep- 

 tional progress. A town has become a 

 city, the head of its municipality a lord 

 mayor ; its area has been enlarged by more 

 than one fifth ; its population has increased 

 from about 280,000 to 479,000. Communi- 

 cation has been facilitated by the construc- 

 tion of nearly thirty-eight miles of electric 

 tramways for home service and of new 

 railways, including alternative routes to 

 Manchester and London. The supplies of 

 electricity, gas and water have more than 

 kept pace with the wants of the city. The 

 first was just being attempted in 1879 ; the 

 second has now twenty-three times as many 

 consumers as in those days ; the story- of 

 the third has been told by one who knows 

 it well, so that it is enough for me to say 

 your water supply can not be surpassed 

 for quantity and quality by any in the 

 kingdom. Nor has Sheffield fallen behind 

 other cities in its public buildings. In 

 1897 your handsome town hall was opened 

 by the late Queen Victoria; the new post 

 office, appropriately built and adorned 

 with material from almost local sources, 

 was inaugurated less than two months ago. 

 The Jlappin Art Gallery commemorates 

 the munificence of those whose name it 

 bears, and fosters that love of the beautiful 

 which Ruskin sought to awaken by his gen-
