drugs and their galenical preparations. His 

 researches in this direction, often in conjunction 

 with M. Herissey, M. Bridel, and other of his 

 assistants and pupils, gained for him a world-wide 

 reputation. His investigation of the constituents 

 of gentian root and of the changes brought about 

 by enzymes during the drying of the root and 

 the making and keeping of preparations made 

 from it may well .serve as a model for future 

 workers. The latter years of his life were mainly 

 devoted to the study of the synthetical as well as 

 the analytical action of enzymes, in which field 

 remarkable results were obtained. 



To his scientific attainments Bourquelot added a 

 personal charm that fascinated everyone brought 

 into contact with him. His unfailing courtesy 

 and friendly disposition endeared him to all. He 

 was one of the most eloquent of lecturers, and 

 those who were fortunate enough to hear his lec- 

 ture on " The Synthesis of Glucosides by Fer- 

 ments " at the International Congress of Phar- 

 macy at The Hague in 191 3 will long remember 

 his admirable luciditv, clear enunciation, and ex- 

 quisite delivery. 



Though Bourquelot had been in indifferent 

 health for the last two or three years the eiid came 

 with dramatic rapidity, and pharmacy was robbed 

 of one of its most brilliant exponents. 



Col. R. a. Wauhofe. 



Col. R. a. Wauhope, whose death is an- 

 nounced, was, perhaps, better known for the 

 splendid quality of his practical work at map- 

 making on the Indian frontier (and beyond it) 

 than for researches into those branches of geo- 

 detic science which form the special objective of 

 that section of the Indian Survey Department 

 which is centred in Dehra Dun. He was one of 

 the first and best of those surveyors who 

 reformed the antiquated methods of geographical 

 reconnaissance and proved that sound square 

 mapping may be evolved on precisely the same 

 principles of triangulation' and topography in the 

 field of an expedition or a campaign as govern 

 the output of Ordnance mapping in the quiet 

 fields of home survey. 



Col. Wauhope 's science consisted in the clever 

 combination of exact methods, where they were 

 possible, with the scientific adaptation of inexact 

 methods (that is to say, methods not ordinarily 

 recognised as permissible under normal conditions 

 of map-making), and obtaining therefrom results 

 which have proved to be satisfactory. The best 

 instance of such adaptation was afforded when 

 he fixed the initial point of the Russo- 

 Afghan boundary at the head of Lake Victoria, in 

 the Pamirs, by the method of instrumental re- 

 section from distant Himalayan peaks (the posi- 

 tion of which had been determined by a regular 

 geodetic series of the Indian triangulation) 

 in circumstances where direct intersection from 

 a regular series across the Himalayas was im- 

 possible. Such a direct series was eventually 

 carried through with much difficulty and at great 

 expense of money and time from India to the

same point, when it was found in the first place 

 that tne result in absolute values of latitude and 

 longitude was almost coincident with Wau- 

 hope's value, and, in the second, that it was 

 doubtful whether the result of direct triangulation 

 completed under abnormal conditions was the 

 more trustworthy of the two. In this special case 

 it must be remarked that few surveyors possess 

 that physical capacity which enabled Col. 

 Wauhope to attain the elevations necessary for 

 observation. T. H. H. 



Mr. George Clinch, the librarian of the Society 

 of .Antiquaries, whose death, on February 2, we 

 regret to record, joined the staff of the society 

 in January, i8g6, having previously been em- 

 ployed at the British Museum. In May, 1886, he 

 exhibited to the society a collec,tion of flint im- 

 plements found by him during eight years in 

 West Wickham, Kent. In December, 1888, Mr. 

 Clinch reported to the society the results of ex- 

 cavations made by him during the ten previous 

 years in the supposed pit-dwelling at Hayes Com- 

 mon, in the same county. Later, he published a 

 volume entitled "Antiquarian Jottings," describ- 

 ing in a popular manner these and other re- 

 searches in the same district. Mr. Clinch also 

 wrote a number of the "Little Guides," and a 

 work on old English churches. He prepared 

 the annual Lists of Archaeological Papers after 

 they had been discontinued by Sir Laurence 

 Gomme. As librarian he earned the esteem of 

 the fellows and others using the library by his 

 courtesy and readiness to assist. He was in his 

 sixty-first year. 



The death is announced, in his sixty-sixth year, 

 of Dr. William Thompson Sedgwick, who had 

 been connected with the Massachusetts Institute 

 of Technology since 1883 as successively assistant 

 professor, associate professor, and full professor 

 of biologv. He had also been, since 1897, curator 

 of the Lowell Institute, Boston, and since 1902 a 

 member of the advisory board of the hygienic 

 laboratory of the L^.S. Public Health Service. 

 Prof. Sedgwick was author of " Principles of Sani- 

 tary Science and Public Health," and joint author 

 of "General Biology," "The Human Mechanism," 

 and "A Short History of Science." 



We much regret to announce the death, on 

 February 17, at ninety-one years of age, of Dr. 

 W. Odling, F.R.S., Waynflete professor of 

 chemistry at the University of Oxford from 1872 

 to 1912 ; also on February 21, at seventy-eight 

 years of age, of Prof. L. C. Miall, F.R.S., 

 Emeritus professor of biology at the University 

 of Leeds; and on February 22, in his eighty-fifth 

 year, of Prof. R. B. Clifton, F.R.S., latelv 

 professor of experimental philosophy in the L^ni- 

 versity of Oxford. 



The death is announced, on February 16, in 

 his seventy-ninth year, of Mr. C. Grover, for 

 many years astronomical assistant at Sir C. E. 

 Peek's observatory at Rousdon, Devon.
