OBITUARIES 



CHARLES SMART ROY 

 Born at Arbroath, 1854. Died at Cambridge, October 4, 1897 



The death of the professor of pathology in the University of Cam- 

 bridge is a serious loss to the scientific study of that subject. Roy 

 received his training at St Andrews and Edinburgh. His earliest 

 research work, that on the pleuro-pneumonia of cattle, was conducted at 

 London, chiefly in the Brown Institution, of which Burdon-Sanderson 

 was head. Proceeding to Berlin, he studied in the laboratories of 

 Virchow and Du Bois-Reymond, and produced his paper " On the 

 influences which modify the work of the heart," published in the 

 Journal of Physiology. In 1879 Roy became assistant at the Physio- 

 logical Institute of Strassburg University under Prof. Goltz, where he 

 invented the sphygmotonometer and other instruments for measuring 

 the changes in blood-vessels. Here also he invented the well-known 

 ether freezing microtome. Passing next to Cohnheim's Institute at 

 Leipzig, he invented the renal oncometer for the study of variations 

 in blood-flow through the kidney. From here in 1880 he came to 

 Cambridge as George Henry Lewes' student in physiology, and 

 worked in the laboratory of Prof. Michael Foster. In 1882 Roy 

 succeeded Dr Greenfield as Director of the Brown Institution, a post 

 which he held for two and a half years, during which time he visited 

 the Argentine Republic to investigate a disease raging among the 

 cattle of Entre Rios. In 1884 he was elected a Fellow of the Royal 

 Society and to the newly-founded chair of pathology at Cambridge. 

 His chief work was on the mammalian heart, partly carried out in 

 conjunction with Prof. Adami. In prosecuting this research he 

 invented yet other ingenious instruments. Among his students at 

 Cambridge may be mentioned the names of Kanthack, Hankin, 

 Griffiths, Lorrain-Smith, Cobbett, Lloyd-Jones, Rolleston, and 

 Wesbrook. Many of these came as J. Lucas Walker's students in 

 pathology, an endowment which he himself was largely instrumental 

 in securing. Prof. Roy's health had been failing for some time, and 

 for the past year his work at Cambridge has been undertaken by Dr 

 Kanthack, who has now succeeded him. 



PETER BELLINGER BRODIE 

 Born 1815. Died November 1, 1897 



The veteran geologist, the Rev. P. B. Brodie, who had been a Fellow 

 of the Geological Society of London for more than sixty years, passed 

 away on the first day of last month. He was born in London in 1815,
