Geologists will regret to learn that Dr. 

 Wheelton Hind died on June 21. Dr. Hind was 

 born at Roxeth, near Harrow, in i860, and 

 graduated in medicine and surgery in the Uni- 

 versity of London, also gaining the fellowship 

 of the Royal College of Surgeons. He began 

 practice at Stoke-on-Trent more than thirty 

 years ago, and soon occupied a prominent place 

 among the surgeons of North Staffordshire. 

 His recreation from the first was field-geology, 

 which suited both his athletic activity and his 

 eagerness for purely scientific work. His early 

 studies coincided with the movement initiated 

 by Lapworth and others for the more exact 

 correlation of stratified rocks by a very detailed 

 study of their contained fossils ; and Dr. Hind 

 proceeded to apply this new method of "zoning," 

 as it was termed, to the Carboniferous rocks of 

 the neighbourhood in which he resided. His 

 success in discovering the regular order in which 

 the different assemblages of fossils occurred in 

 Staffordshire and Derbyshire gradually led him 

 further afield. He co-operated with members of 

 the Geological Survey, and after extended re- 

 searches in Lancashire and Yorkshire he joined 

 Mr. J. Allen Howe in 1901 in contributing to the 

 Geological Society of London a fundamentally im- 

 portant memoir on the classification of the Lower 

 Carboniferous rocks of north-central England. 

 Dr. Hind also recognised that, for the purposes 

 of the stratigraphical geologist, the species of 

 Carboniferous MoUusca neede'd more exact defini- 

 tion than had previously been attempted, and he 

 devoted much labour to adding two finely illus- 

 trated monographs on the subject to the series 

 published by the Palaeontographical Society. Some 

 of the molluscs proved to be of value for recog- 

 nising the various seams of coal in the Stafford- 

 shire coalfield, and in '1903 Dr. Hind and Mr. 

 J. T. Stobbs prepared an illustrated wall-chart cf 

 them for the use of the practical miner. On the 

 outbreak of war in 1914 Dr. Hind joined the 

 Army as a gunner, and took part in some engage- 

 ments in France ; but he was afterwards employed 

 as surgeon, and attained the rank of lieutenant- 

 colonel. He received the Lyell medal from the 

 Geological Society of London in 191 7. 



The death, at the age of seventy-eight, of Mr. 

 James Kennedy is a serious loss to Oriental 

 studies. The son of an Indian missionary, Mr. 

 Kennedy was employed in the Civil Service of India 

 from 1863 to 1900. After his retirement he was a 

 leading figure in the Royal Asiatic Society, serving 

 as treasurer until illness compelled his resignation, 

 and winning the respect of his colleagues by his 

 learning, business capacity, and kindliness of 

 nature. He was one of those patient workers 

 who are always collecting materials, hoping for 

 new light on difficult problems, and thus he failed 

 to accomplish his projected task, a history of the 

 relations of Indian culture with those of Nearer 

 Asia. He contributed to the Proceedings of the 

 Royal Asiatic Society several valuable mono- 

 graphs, the most important being devoted to the 

 NO. 2644, VOL. 105] 



early trade intercourse of Babylonia with India, 

 the cults of Krishna, and the .Aryans, the last 

 published only a few months before his death. 

 Though some of his ingenious speculations failed 

 to meet with general acceptance, it is much to be 

 regretted that he failed to accomplish the work 

 to which his life was devoted. 



Last week there died in Paris, in his eighty- 

 second year, M. Adolphe Carnot, a member of 

 the Academy of Sciences and of the Legion of 

 Honour. M. Carnot was the grandson of M. 

 Lazare Carnot and the son of M. Hippolyte Car- 

 not, the Minister of Public Instruction in the Pro- 

 visional Government of 1848. President Sadi 

 Carnot was his elder brother. For many years 

 M. A. Carnot held a professorship at the Ecole 

 Superieure des Mines, and was afterwards its 

 honorary director. He was also Inspector-General 

 of Mines in France. 



M. Carnot 's scientific reputation rests chiefly on 

 his contributions to analytical methods, and his 

 treatise on the analysis of mineral substances is 

 the standard French work on this subject. It 

 comprises a detailed account of the occurrence, 

 properties, reactions, methods of separation, and 

 analysis of all the metals, including the rare 

 metals, which are very fully described. The in- 

 formation given with reference to the rare metals 

 is based largely on his own original work. He 

 was a frequent contributor to the Annates des 

 Mines, and published papers on methods of deter- 

 rqining phosphorus, silicon, potassium, iodine, 

 chlorine, bromine, vanadium, molybdenum, 

 chromium, etc. In 1900 there appeared his 

 important joint paper with Goutal on the veri- 

 fication of compounds existing in iron and steel 

 by using reagents with which to dissolve out 

 certain of the constituents. This paper is one of 

 the best that have appeared on this subject. 



We regret to have to record the death of Mr. 

 Hammersley Heenan, which took place on 

 June 17. Mr. Heenan was born in 1847, and 

 had been a member of the Institution of Mechan- 

 ical Engineers since 1875, and of the Institution 

 of Civil Engineers since 1876. An account of 

 his career appears in Engineering for June 25. 

 At seventeen years of age he went to India and 

 spent about fifteen years in the Public Works 

 Department. Mr. Heenan returned to England 

 in 1880 and founded the firm of Heenan and 

 Froude, Ltd., of which he was chairman and 

 managing director until his retirement two years 

 ago. The firm is principally engaged on 

 bridges and structural work generally. .A.mong 

 its undertakings is the Blackpool Tower. 

 During the war Mr. Heenan rendered great 

 service both in his personal capacity and in apply- 

 ing the resources of his works to the manufacture 

 of munitions. 



The death is announced of Dr. J. H. Hyslop, 

 the founder of the .\merican Society of Psychical 

 Research.
