Annual Report of the Council. lv 



It remains to mention the titles of other communications 

 made to the Royal and chemical societies after the vanadium 

 research was completed : " On a new chloride of Uranium," 

 " Note on the Specific Gravity of the vapour of the chlorides of 

 Thallium and Lead," " A study of some of the Earth-metals 

 contained in Samarskite," and in conjunction with Professor 

 Schuster papers on the Spectrum of Terbium and on the 

 Absorption-spectra of Potassium and Sodium. 



Soon after Roscoe's election to the chair of chemistry in 

 Owens College he became a member of this Society. His 

 connection with it was long and intimate. He became joint 

 secretary with Dr. E. Schunck in i860 and then, with Mr. Baxen- 

 dell, remained secretary till 1873. Three years later he became 

 Vice-President and in 1882 was elected President of the Society. 

 During his long membership Roscoe contributed many papers 

 to our Memoirs, the titles of which will be found below. 



Roscoe's scientific eminence and his great work in connection 

 with education brought him many honours both in this country 

 and abroad. He was elected President of the British Association 

 in 1887 and to the Vice-Chancellorship of the University of 

 London in 1896. He had received the honour of Knighthood 

 in 1884 and in 1909 was sworn of the Privy Council. 



He died, somewhat suddenly, on December 18th, 19 15, at 

 the age of 82.

 " The existence of a crystallizable carbon compound and free 



sulphur in the Alais Meteorite." (1863). 

 "Note on the amount of carbonic acid contained in the air of
