which the younger worker and the elder will go down to posterity- 

 together, were the last that Cohnheim himself ever entered upon. 

 During their prosecution it was a delight to him to admire the 

 wonderful skill and easy dexterity of his younger colleague ; he saw 

 that those gifts were well suited to advance scientific pathology in 

 the very direction in which he himself believed it could prosper 

 best." Cohnheim's death in 1884, at the early age of forty-five, was 

 felt by Roy as a severe personal loss. He often spoke of Cohnheim 

 in terms of enthusiastic admiration. He looked upon himself as in a 

 way representing in this country the leadership which Cohnheim held 

 in the new school of pathology in Germany. Roy stayed at Leipzig 

 nearly a year. While there he received the " George Henry Lewes 

 Studentship " for research in physiology, founded by " George Eliot." 

 He was its first recipient. 



In tenure of this studentship he worked in Prof. Michael Foster's 

 laboratory at Cambridge. Thence he issued his paper, " On the 

 Physiology and Pathology of the Spleen." This communication 

 contains his discovery of an autochthonous rhythmic tonicity in 

 the mammalian spleen ; the vasomoter reactions of the organ were 

 also elucidated. In 1882 Roy was appointed Professor Superintendent 

 of the Brown Institution. There he plunged into the work on the 

 actions of the mammalian heart, work which he never relinquished 

 until nervous breakdown divorced him from all laboratory cares. 



In the year 1884 Roy was elected to the Fellowship of the Society, 

 and very shortly afterwards he was appointed to the newly-established 

 Chair of Pathology in the University of Cambridge. He was then in 

 his thirtieth year. Although his activity at Cambridge during his 

 later tenure of the chair suffered under his failure in health, and in 

 the early period was hampered by want of accommodation in the 

 matter of laboratory room and equipment, Roy's work for pathology 

 in the University, for the short time that it had free scope, was 

 marked by conspicuous success in many ways. In 1887 he succeeded 

 in securing the foundation for pathology of the J. Lucas Walker 

 Studentships. The selection of these students lay largely with him, 

 and in his laboratory the main part or the whole of their work was 

 accomplished. The recital of their names J. G. Adami, W. Hunter, 

 Alfred Kanthack, Lorrain Smith, W. Wesbrook, Louis Cobbett 

 suffices to indicate the sterling value of Roy's judgment and discretion 

 in this part of his office. 



In 1889 buildings vacated by the Chemistry School were trans- 

 formed and refitted to receive the department of Pathology. From 

 the better laboratory proceeded a rapid output of excellent work in 

 experimental pathology ; researches on endocardial pressures, on the 

 relation between heart beat and pulse wave, on the mechanism of the-
