(e) Phenomena under Narcosis in the Guinea-pig and other Animals. — 

 In 1909 the present author described certain phenomena which occur under 



narcosis in the guinea-pig (46), and he has given more detailed observations 

 in subseqent papers (47, 48, 51, 54, 55). These seem to have a direct 

 bearing upon the question of the nature of the Brown-Sequard phenomenon.
