4o6 THE POPULAR SCIENCE MONTHLY. 



Franco-Prussian War, then in progress : " And here may I remind you 

 of the cosmopolitan character of science, of the fact that it is mainly 

 to the brotherly intercourse of those interested in science, and in its 

 application to the arts and manufactures in different countries, that 

 we must look as the small but living fire which in the end will surely 

 serve to melt down national animosities, and to render impossible the 

 breaking out of disasters so fatal to the welfare of humanity as that 

 of which we are now unfortunately the spectators ? " 



Besides the researches to which reference has already been made, 

 and numerous papers in the " Philosophical Transactions " and the 

 scientific periodicals, Professor Roscoe has published " Lessons in 

 Practical Chemistry," a work which has been translated into Ger- 

 man, Russian, Hungarian, and Italian, and republished in this coun- 

 try ; " Lectures on Spectrum Analysis," of which a fifth edition 

 was published in 1878 ; a " Junior Course of Practical Chemistry," 

 prepared by himself and Francis Jones in 1873 ; and, conjointly with 

 Professor Schorlemmer, a large "Treatise on Chemistry," in three 

 volumes. The last work was pronounced by " Nature," in a review of 

 the first two volumes, one which, " when finished, will afford the most 

 complete systematic exposition of the existing state of chemical science 

 that has yet appeared in the English language " ; and by Professor 

 Watts as forming a treatise on inorganic chemistry " of which English 

 science may well be proud." To " Nature " he contributed affection- 

 ate biographies of Liebig and Bunsen. He was also joint editor, with 

 Professor Huxley and Balfour Stewart, of Macmillan's " Science 

 Primer " series, and author of the " Primer of Chemistry." He is 

 Examiner in Chemistry to the Science and Art Department. He was 

 elected President of the Chemical Society of London in 1880, Presi- 

 dent of the Literary and Philosophical Society of Manchester in 

 1882 ; and is a member of the Royal Commission on Technical In- 

 struction. He was knighted in 1884, at about the time of the meeting 

 of the British Association at Montreal.
