refused to leave when asked to go to Paris, just as Bunsen 

 refused to quit Heidelberg for Berlin. 



Raoult received many honours : i\\Q prix Lacaze in 1889, 

 the Davy medal of the Royal Society in 1892, the great ' prix 

 biennaV of 20,000 francs of the French Institute in 1S95. He 

 was elected a Correspondent of the French Academy of Sciences 

 in 1890, and Foreign Member of the Chemical Society in 1898. 

 He had been an honorary member of our Society since 1892. 



The above notice is based partly on personal knowledge, but mainly on 

 information kindly supplied by M. Recoura ; on speeches made at M. Raoult's 

 funeral by M. Boirac, rector of the Academie de Grenoble, and M. Kilian, 

 professor at the University of Grenoble ; on a preface to M. Raoult's book 

 La Cryoscopie, written by M. R. Lespieau ; and on the abstract of Prof, 

 van't Hoffs Memorial Lecture on Raoult, given to the Chemical Society, 

 March 26th, 1902, {Chein. Soc. Proc, 1902, p. 81).

Henry Augustus Rowland, Ph.D., LL.D., For. Mem. 

 R.S., Professor of Physics in the Johns Hopkins University, 

 Baltimore, U.S., Honorary Member of this Society since 1894, 

 died on the i6th April, 1901. 



Born at Henesdale, Pa., on the 27th Novetnber, 1848, he 

 was trained as an engineer at the Troy Polytechnic Institute, 

 spent a short time as civil engineer on the railway, and in 187 1 

 became teacher of Physics at Wooster College. Next year he 

 returned to Troy, first as instructor in Physics, then as professor 

 of Physics, and in 1875 became professor of Physics at Baltimore. 

 He had already published several papers on magnetic permea- 

 bility, and during his visit to Europe previous to commencing his 

 duties at Baltimore he carried out in Helmholtz's laboratory at 

 Berlin, his important experiments on the magnetic effect of 

 electrical convection. His work at the Johns. Hopkins 

 University was confined almost exclusively to research and post 

 graduate instruction. He turned his attention first to a deter- 

 mination of the Mechanical Equivalent of Heat, the result of 

 which he published in 1880, and in 1882 described his wonderful 

 concave grating, by means of which he carried out a long series of
