90 Annals of the Philosophical Club 



SIR FRANCIS DARWIN, third son of Charles R. Darwin, was born 

 at Down, Kent, on Aug. i6th, 1848, graduated with high honours 

 in Natural Science from Trinity College, Cambridge, was elected 

 a Fellow of Christ's College, and took the M.B. degree. Then he 

 co-operated with his father in scientific investigation, after whose 

 death he returned to Cambridge, and wrote more than one valuable 

 memoir on his life and work in addition to his own contributions 

 to science. He was elected F.R.S. in 1882, was President of the 

 British Association in 1908, received the medal founded in honour 

 of his father in 1912, and was knighted in 1913. 



1895. At the Anniversary Meeting on April a6th, Mr. 

 W. Crookes was elected Treasurer in place of Dr. Blanford, 

 and the vacancies made by the transference of Professor 

 Allman and Dr. Giinther to the list of honorary supernume- 

 rary members were filled by the election of Mr. Ludwig 

 Mond and Dr. W. J. Russell. 



DR. LUDWIG MOND, a merchant's son, was born at Cassel on 

 March 7th, 1839, and educated at Marburg and Heidelberg. After 

 having made more than one discovery of commercial value, such 

 as the recovery of sulphur from waste products, he started the great 

 alkali works at Winnington, where he made other lucrative dis- 

 coveries, among them an important method for extracting nickel 

 from its ores. He was elected F.R.S. in 1891, was an honorary 

 doctor of Manchester and Oxford, besides Heidelberg and Padua, 

 and died Dec. nth, 1909. " He was a man of great scientific 

 attainments, of indomitable resource and energy, with a genius for 

 divining the industrial possibilities of discoveries in pure science." 

 His interests were in science, music, art (he formed a fine collection 

 of pictures, especially early Italian), and he unostentatiously devoted 

 no small part of his great wealth to the promotion of science. In 

 its annals his benefactions to the Royal Society and its Catalogue 

 of Scientific Papers, with the founding and endowment of the Mond 

 Laboratory at the Royal Institution, to mention no others, will long 

 keep his memory green. 



DR. WILLIAM JAMES RUSSELL was connected with America and 

 France, but was son of a banker at Gloucester, born on May 2oth, 

 1830. He began to study chemistry in 1847 at University College, 

 London, then assisted Professor Frankland at Manchester. From 

 1883 to 1885 he worked at Heidelberg, where he took the Ph.D. 

 degree, and after returning to England investigated gas analysis 

 and cobalt, being ultimately appointed Lecturer on Chemistry at 

 St. Bartholomew's hi 1870, which post he held till 1897. He was 

 elected F.R.S. in 1872, having already begun to study absorption 

 spectra, and did much valuable work on impurities in London air
