practice, in the evening of "his days, he took np the examination of 

 solar spots, and their possible relation to meteorology. 



Stephen Parkinson was well known to Cambridge men as a mathe- 

 matician, and was the author of several mathematical works in 

 common use in the University. 



John Percy was for more than forty years a Fellow of the Society, 

 and has served on the Conncil. Many years ago I was myself asso- 

 ciated with him at the Government School of Mines, where we both 

 were lecturers together. He was a man of accnrate knowledge but 

 of a, retiring character, and is perhaps best known to the world 

 through his excellent work on metallurgy, the value of which is 

 evidenced by the fact of its having been translated both into French 

 and German. 



Owen Rees, also for more than forty years a Fellow of the Society, 

 did good service in the application of chemistry to the elucidation of 

 disease. 



Miles Joseph Berkeley, who died at the advanced age of eighty-six, 

 was distinguished as a cryptogamic botanist ; indeed in this branch 

 of botanical science he was long looked up to as the leading authority. 



Our late Fellow John Ball was for a long time intimately associated 

 with the work of the Society. Besides serving on the Council, he 

 has very frequently assisted us on various Committees. It will be 

 recollected that he was associated with Sir Joseph Hooker in 

 botanical exploration, and the two, at no little personal risk, ascended 

 the Atlas range on the northern side, being the first Europeans who 

 had penetrated so far. Fond of travel, and of mountain climbing, he 

 was led to take up the subject of botany ; and in relation to this 

 science, as well as to meteorology and geology, he turned his travels 

 to good account. 



George West Royston-Pigott took up the subject of improvements 

 in the microscope, specially as regards the correction of the residue 

 of spherical aberration, and a paper of his on the subject is printed 

 in the ' Philosophical Transactions.' 



John Frederic La Trobe-Bateman, who died in June, will long be 

 remembered for his important engineering works, especially in relation 

 to the supply of water to large towns. 



William Henry Bristow was associated with De la Beche, Edward 

 Forbes, and other geologists in the early history of the Geological 

 Survey, and remained in that department of the Civil Service of the 

 country, in which he had been promoted to the post of Senior 

 Director, almost up to the end of his life. He particularly distin- 

 guished himself by the careful and detailed manner in which he 

 carried out the mapping of the Cretaceous and Jurassic rocks of the 

 South of England. His maps and descriptions of that region have 

 become classical in English geology. Outside of his official work he
