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. Drep NovemsBer 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, 
and early proceeded to Cambridge, where he came under the influence
