Obituary. 



Dr. Alexander Smith, professor of chemistry and head of 

 the chemical department in Columbia University from 1911 to 

 1921, died in Edinburgh, his birthplace, on September 8 at the 

 age of fifty-seven years. Professor Smith held many University 

 positions, contributed important researches on the forms of 

 sulphur, and (with A. W. C. Menzies) on vapor pressures, wrote 

 numerous useful textbooks and in brief was a man of great energy 

 and wide influence. 



Dr. F. T. Trouton, emeritus professor of physics in the Uni- 

 versity of London, died on September 21 at the age of fifty-eight 

 years. Born in Dublin in 1863, he was graduated from Trinity 

 College where he early showed his rare keenness of mind. He 

 was made at once assistant to the professor of physics, and in 

 1902 became Quain professor in University College, London. He 

 will be remembered for many important researches, those leading 

 to the establishment of Trouton's Law, on Hertzian waves, on 

 the viscosity of solids and others of no less importance.

 August 27 at his home in Brockenhurst, at the age of eighty-two
