 Has during the past four years devoted his entire time to research 

 work in, and teaching of Physiology, especially the chemical 

 side of that science. Has published the following, among other

made important additions to chemical industrial processes and 

 products, especially with reference to the alkali industry, havings 

 improved the mode of manufacture of carbonate of soda, caustic 

 soda, hydrochloric acid, chlorine, ammoniacal products, and ga& 

 generating furnaces, &c In 1863 he developed what is known 

 as the " Mond Process of Sulphur Recovery from Alkali Waste," 

 and has since that date devoted himself to the introduction and 

 development of the ammonia soda process of alkali manufacture 

 into England. Author of various papers in Rept. Brit. Assoc, 

 Journ. Soc Chem. Ind. 



William Napier Shaw, M.A., 



Fellow of Emmanual College, Cambridge. Was nominated by 

 Lord Kayleigh as one of the Demonstrators of Physics in the 

 Cavendish Laboratory at Cambridge. He held that position 

 from 1880 to 1887, and he has since continued his connection 

 with the Laboratory as University Lecturer in Physics. His 

 knowledge of the manner in which the teaching of Physics is 

 conducted in the great German Universities (acquired at Berlin 

 under Helmholtz) enabled him to bear an important part in the 

 organization of the laboratory. A considerable part of the suc- 

 cess of the Cambridge School of Physics is due to his exertions, 

 backed by his knowledge of Physics. Author of numerous 

 books and papers, of which the' following are especially worthy 

 of notice:— " Practical Physics" (jointly wiih Mr. Glazebrook), 

 Longmans, 1885; "Practical Work in the Cavendish Labora- 

 tory," University Press, 1886 ; " Faraday's Law of Electrolysis-

 polarizing prisms, in the method of adjusting resistance coils, and 

 in sundry electrical apparatus. Member of Council of the
