ADDRESS TO THE GEOLOGICAL SECTIOy OF 



THE BRITISH ASSOCIATIOX FOR THE 

 ADVAXCEMEXT OF SCIEXCE.* 



There are two circumstances which in- 

 vest the fact of my presidencj' of fhe sec- 

 tion this year with peculiar pleasure to 

 myself. The first public lecture I ever gave 

 was in the Town Hall at Birkdale in 1882, 

 and the first of the fifteen meetings of the 

 British As.sociation which I have attended 

 was that held in Southport in 1883. 



There is still a third reason that this 

 meeting is in many respects a geological 

 meeting. A paleobotanist is presiding over 

 Section K, and the council has invited, for 

 the first time for many years, one geologist 

 to deliver an evening discourse and another 

 to give the address to artisans. I need 

 hardly say that we are all looking forward 

 to the lectures of Dr. Rowe and Dr. Flett 

 with keen anticipation. To the one for 

 his successful use of new methods of de- 

 veloping fossils and his scientific employ- 

 ment of the material thus prepared in 

 stratigraphic research; to the other for his 

 prompt, daring and business-like expedition 

 to the scene of recent volcanic activity in 

 the West Indies, during which he and his 

 colleague. Dr. Tempest Anderson, collected 

 so many important facts and brought away 

 so much new knowledge of the mechanism 

 of that disastrous and exceptional volcanic 

 otitbreak.
