"Vol. 6S.'] ANNIVEESAEY ADDKESS OF THE PRESIDENT. Ixi 



at Cardiff in 1891. He attended the Montreal meeting of the 

 British Association in 1884 as a Vice-President of Section C, and 

 on that occasion made a short tour through the United States. 

 During the last few years he had lived in retirement at Chesham 

 ]3ois (Buckinghamshire), where he died on April 13th, 1911, in his 

 ninety-second year. [A. S. W.] 



Meevin Heebert Nevil Story-Maskelyne was born on 

 September 3rd, 1823, at Basset Down House, near Swindon, and he 

 died at the same place on May 20th, 1911, in his eighty-eighth year. 

 Both his father and grandfather were, like himself, distinguished 

 Pellows of the Royal Society. He graduated at Oxford in Mathe- 

 matics, and, after working for some time at chemistry, was appointed 

 Deputy-Reader in Mineralogy at that University in 1850, Reader in 

 1856, and Professor in 1861, a post which he continued to hold until 

 1895, when he was succeeded by his former pupil H. A. (now Sir 

 Henry) Miers. He also held the appointment of Keeper of Minerals 

 in the British Museum from 1857 until 1880, the condition of 

 tenure of his Professorship permitting, at that time, this duplication 

 of office. At Oxford he exercised his influence in favour of the 

 establishment of science teaching in the University, and in 

 promoting the building of a science museum there. During his 

 term of office at the British Museum he rendered great service, 

 not only by his original work on mineralogy and allied subjects, 

 but in the extension and improvement of the mineral collections, 

 which he increased up to nearly 50,000 specimens. He had, 

 however, many other interests, largely connected with his position 

 as a landowner in Wiltshire ; and, in addition to serving on the 

 •County Council and acting as Chairman of its Agricultural 

 Committee, he entered Parliament in 1880 and remained a member 

 till 1892. He published a large number of papers on mineralogical 

 subjects, dealing especially with the diamond, with meteorites (in 

 which he discovered enstatite), and with the symmetry of crystals, 

 a property on which he laid great stress. He discovered several new 

 species of minerals, and in 1895 published an important treatise 

 on crystallography. His chief contributions to geology comprise 

 a paper on the petrology of the Stones of Stonehenge, another on 

 the petrology of the Transit of Venus Expedition 1874-75, one 

 on an artificial dioptase-rock, and, finally, one on an enstatite-rock 

 from South Africa. He was an Honorary D.Sc. of Oxford and an 

 JEonorary Fellow of Wadham College. His services to mineralogy
