power, for many years an active member of Parliament and Chairman 

 of the London, Brighton, and South Coast Railway Company. Full 

 obituary notices of those here briefly enumerated, as well as of several 

 other deceased Fellows, will be found in the following pages. 



Alereb L. 0. Des Cloizeatjx, Membre de I'lnstitut de France, 

 Foreign Member of the Hoyal Society, and Professor of Mineralogy 

 in the Museum of Natural History, Paris, was elected a Foreign 

 Member of this Society in 1884. He received the Wollaston Medal 

 in 1886. Sir Warington Smyth, when receiving the Medal on 

 behalf of M. Des Cloizeaux, said, ' It is more especially in the wide 

 and successful application of Wollaston's invention of the Reflection 

 Goniometer that Des Cloizeaux has attained so deserved an emi- 

 nence, following closely upon the steps of Prof. Miller, to whom, 

 in his admirable manual, he pays so higb a compliment.' Des 

 Cloizeaux's first paper was published 54 years ago, and was 

 the beginning of a long series treating of the forms and optical 

 characters of crystals. After being Professor of Mineralogy for 

 eighteen years at the Ecole ISTormale Superieure, he was appointed 

 to the charge of the minerals at the Musee d'Histoire JSTaturelle, in 

 which office he remained until he reached the limit of age pre- 

 scribed by the rules of the French Civil Service. His fame rests 

 upon the thoroughness and accuracy of his systematic investigation 

 of the crystals of minerals, more especially as regards their optical 

 properties. The results are incorporated in his ' Manuel de 

 Mineralogie,' a standard book of reference. Prof. Des Cloizeaux 

 died, in the 80th year of his age, in May 1897. 



The following is taken from a speech by M. A. Damour, his 

 intimate friend and co-worker for 53 years: — 'In everything he 

 applied himself to the spread of all that he deemed useful, just, 

 and wise. All those who knew him honoured him and loved him. 

 His name as a savant remains in the history of mineralogy ; he 

 there occupies the most honourable place among the founders of 

 this science, and among those who have contributed to its pro- 

 gress and advancement.' 



The death of Edwaed Deinkee Cope on April 14th, 1897, 

 at the comparatively early age of 57, removed from our list of 

 Foreign Correspondents a highly-gifted biologist and one of the 

 best known American men of science. He was born in Philadelphia, 

 July 28th, 1840 ; he attended school in his native city, and also
