and the public collections arranged with a perfection of speci- 

 mens and arrangement which has never been surpassed, while the 

 value and interest of the Avhole Avas enhanced by the lucidity 

 of the written descriptions and guides to study of the collections. 

 His manifold administrative duties did not wholly' engross his 

 attention, and he found time for independent research, of which 

 the most important was his investigation of the transmission of 

 light through crystals, leading up to his memoir on Optical Indi- 

 catrices, published in 1892. In this his mathematical training 

 enabled him to elucidate the interpretation of his observations, to 

 clear up a subject which had been previously ill understood, and 

 to place an invaluable means of research at the disposal of workers 

 at mineralogy or petrograph3\ When he Avas made Director of 

 the Natural History Museum in 1909, advancing years and a 

 severe illness had deprived him of much of his former energy ; but 

 he still retained his quiet studious character, ever helpful to all 

 enquirers, with a kindly tolerance and genially cynical outlook on 

 affairs. Among his services to Gleology special mention may be 

 made of his interest in the Mineralogical Society, which owes 

 much to his inspiration and work as President and Honorary 

 Secretar}^ His merits were not unrecognized, he was elected a 

 Fellow of the Koyal Society in 1889 and a Vice-President in 1910, 

 was a foreign and honorary member of numerous scientific societies,. 

 a recipient of several honorary degrees, and received knighthood in 

 1916. He was elected Fellow of our Society" in 1879, was Vice- 

 President from 1890-93, and the Wollaston Medal Avas aAA'arded 

 to him in 1912. He was superannuated from his official position 

 in 1919, and died unexpectedly of heart-failure on January 6th, 

 1921. 



Henry Hoyte Wtnwood, Avho died at Bath on Christmas Day 

 1920, ten days after he had completed his 90th year, Avas for 

 long a familiar and welcome figure at our meetings. Graduating 

 from Exeter College, Oxford, in 1852, he was admitted to holy 

 orders, but only held a curac}^ for three years. Always an ardent 

 geologist, he was the author of several papers devoted to the local 

 geology of his district, and of the accounts of the geology 

 and meteorology of Bath, prepared for the 1888 meeting of the 

 British Association, but his published Avritings are no measure o£ 

 the services which he rendered to Geology and to the Society, 

 He took a keen interest in the geological collection of the Batli
