42 president's address — section b. 



rAs. has so often been the case, the most striking results have fol- 

 ■i lowed from the co-operation of chemistry with other branches of 

 science, and above all with physics. To attempt to give even the 

 most cursory summary of recent discoveries in the time now avail- 

 able would obviously be fruitless. Art is long, and your patience 

 must be growing short. Fortunately, as regards one of the mo'?t 

 •Jmportant and fundamental problems of chemistry or physics, 

 ' n9,mely the structure of an atom, the present position is to be 

 laid before you by abler exponents. 



I am afraid that the foregoing remarks have been somewhat 

 discursive and fiagmentary. Many of them have been made 

 before by others, some of them many times. But if I have 

 managed to supply my fellow chemists with a few reasons in a 

 handv form for the faith which is in them, I shall be content.
