THE LIFE AND WORKS OF BROWN-SEQUARD. 687 



As an experimenter he occupied himself with researches ceaselessly 

 begun, laid aside, then taken up again and thoroughly carried out, 

 upon the physiology and pathology of the nervous system. 



As a journalist he continued his Journal de Physiologie, abandoned 

 in 1861 for the Archives de Physiologie, published in collaboration 

 with Charcot and Vulpian. Scientific journalism always had for him a 

 particular attraction, in spite of the fatigues and disappointments of 

 the profession. He loved to write according to his own fancy as well 

 as to combine ingenious experiments. He stimulated his collaborators 

 and showed them original work to be done, applauding every novelty, 

 attentive to every mark of talent in young people. He worked much 

 and made others about him work. 



As professor he also made his way and became established, thanks 

 to his personal popularity and to the influence of Agassiz and of Bayer, 

 now more x>owerful than ever as physician to the Emperor, and like- 

 wise supported by letters from Agassiz, who had great influence with 

 Napoleon III. 



Bayer had made a breach in the long-established routine of the fac- 

 ulty and had undertaken a reform which failed for reasons it is unneces- 

 sary to recall here. He profited by his transitory authority to establish, 

 for the benefit of Brown-Sequard, a provisonal course of experimental 

 physiology in the Faculty of Medicine of Paris. Nothing more could 

 be done on the staff, as Brown was not a French citizen. He thus 

 reappeared as a professor where he had been a student in his youth. 

 Claude Bernard, Vulpian, and Brown had climbed up side by side, con- 

 stantly increasing in reputation and discoveries, the ladder of superior 

 instruction by which we are elevated, little by little, to the first rank, 

 by force of merit and the opinion of our peers. 



Brown-Sequard was not made for a didactic lecturer, nor was he 

 likely to carry away his auditors by bursts of borrowed eloquence. 

 But he excelled in displaying his own discoveries with a sincerity that 

 was not wanting in finesse. His researches on the hereditary trans- 

 mission of nervous lesions attracted the attention of both physicians 

 and naturalists. They were also in close relation with the theories of 

 Lamarck and Darwin on the gradual modification of organisms trans- 

 formed both by natural selection and the artificial conditions of exist- 

 ence. 



But Brown could not briug himself to continue a fixed residence 

 anywhere. During the siege of Paris he was on a journey to the 

 United States, where he gave a series of lectures of which the proceeds 

 were intended for our wounded. 



In 1872 there' was another change. He married a second time, his 

 bride being an American, Mrs. Carlyle, of Cincinnati, by whom he had 

 a daughter, now the wife of a physician in Dublin. He gave up his 

 provisional chair in Paris at the moment when measures had been 

 taken to naturalize him, so that it could be made permanent, and estab-
