Sir Ernest Rutherford writes that Moseley was " one of those rare 

 examples of a mati who was a born investigator." This quality ho 

 inherited from his father ; and it is noteworthy that his grand- 

 father Canon Moseley, E.R.S., was a distinguished and original 

 mathematical physicist, whilst his grandfather on his mother's side, 

 Mr. G-wyn Jeffreys, was also a Fellow of the Royal Society and 

 for many years a leader in the study of Oceanography and Marine 

 Zoology. Professor Rutherford tells us that Harry Moseley 's 

 " undoubted originality and marked capacity as an investigator 

 were very soon ungrudgingly recognized by his co-workers in the 

 laboratory, while his cheerfulness and willingness to help in all 

 possible ways endeared him to all his colleagues." Mr. 0. G-. Darwin, 

 a grandson of Charles Darwin — who worked with him at Manchester 

 and produced with him a joint paper in which they mapped out 

 accurately, for the first time, the spectrum of the characteristic 

 X-radiation from an X-ray tube with a platinum anticathode, — 

 writes that he was without exception or exaggeration the most 

 brilliant man whom he had ever come across. Others who came 

 to know him well in Manchester write of his charm of manner 

 and personality, of his kindliness and unselfishness and care for 

 the interests of others. As a boy (when I knew him best) he 

 was a keen and observant naturalist and knew every bird and 

 bird's nest in the neighbourhood of his home. In this and in 

 the collection of flint implements he was enthusiastically aided by 

 his sister. His last letters home from the East were full of 

 observations on the plant-life, the birds, the beasts, and the flint 

 implements of all ages which he found in a day's ramble on the 

 hills where he was encamped. A most happy life of experimental 

 research, with natural history and his garden as relaxations, was 

 assured to one so greatly gifted and beloved, for he had private 

 means and an ideal home. Whilst abroad on active service, in 

 view of possibilities now alas ! realized, Harry Moseley expressed 

 the wish (which will be eventually carried out) to bequeath any 

 property at his disposal to the Royal Society of London " for the 

 furtherance of scientific research." 



I am enabled by the kindness of Dr. Bohr of the University of 

 Manchester, who has been aided by Dr. Makower, to add to this 

 short personal sketch a notice of Moseley's scientific work which 

 will, I am sure, be highly valued by the readers of the Phil. Mag.

Moseley came to Manchester in the spring of 1910 as lecturer 

 and demonstrator in the Physical Laboratories of the University. 

 At that time a great number of scientists from all parts of the 

 world were working in the laboratories under the direction and 

 inspiration of Sir Ernest Rutherford. Moseley at once caught 

 the spirit of the laboratories and applied himself with charac- 

 teristic energy and enthusiasm to the difficult and important 

 problem of determining the number of /3-particles emitted by a
