Obituary.

rHE death of Sir Norman Lockyer on 

 Monday last deprives the world of a great 

 astronomer, and the nation of a force which it 

 can ill afford to lose. Though it had been known 

 for several months that Sir Norman was in a 

 feeble state of health, his many friends cherished 

 the hope that the vigour which was characteristic 

 of him would revive, and that the devoted atten- 

 tion of his wife and daughter would preserve him 

 to us for a few more years ; but this was not to 

 be. The alert mind and acute understanding 

 which influenced so many men and advanced so 

 much scientific work over a period of sixty years 

 or so are now at rest, yet there remains to us a 

 recollection which will not soon be effaced, and 

 there stands in the archives of science a record 

 of his achievement which will command admira- 

 tion so long as the pursuit of knowledge is re- 

 garded as worthy human endeavour. 



In the jubilee issue of Nature in November 

 last Dr. Deslandres, Sir Archibald Geikie, Sir 

 Ray Lankester, and other distinguished men of 

 science paid tribute to the work and influence of 

 the founder of this journal, the volumes of which 

 form an enduring monument to his memory. 

 NO. 2651, VOL. 105] 



Sir Norman was not only a pioneer worker in 

 the fields of science, but also an advocate of the 

 claims of science to recognition in modern polity, 

 and this rare combination was used to further 

 scientific interests as well as to secure the progress 

 of knowledge. He was the embodiment of mental 

 activity, and never relinquished a task to which he 

 had put his hand. Until a short time ago he was 

 as eager to learn of developments and discoveries 

 in astronomical work, and as ready to suggest new 

 lines of research, as a man in the prime of life, 

 and it is difficult to realise that this fund of 

 energy is now no longer available to those of us 

 who derived benefit from it. When Goethe wrote : 

 "The quickening power of science only he can 

 know from whose soul it gushes free," he must 

 have had in mind a researcher of the type of him 

 whose loss we now mourn. 



Sir Norman Lockyer was born at Rugby on 

 May 17, 1836. He was educated at various 

 private schools, and in 1857 received an appoint- 

 ment at the War Office. His work there was so 

 much appreciated that in 1865 he was entrusted 

 with the editorship of the Army Regulations. 

 In 1870 he was appointed secretary of the Duke 

 of Devonshire's Roval Commission on scientific
