264 ROUGH WAYS MADE SMOOTH. 



began to search for the locket under her pillow/ As it had 

 been removed in the interval, ' she was unable to find it, at 

 which she expressed great disappointment, and continued 

 searching for it, with the remark, " It must be there I put 

 it there myself a few minutes ago, and no one can have 

 taken it away." In this state the presence of S. renewed 

 her previous feelings of anger ; and it was only by sending 

 S. out of the room that she could be calmed and induced to 

 sleep. The patient was the subject of many subsequent 

 attacks, in every one of which the anger against S. revived, 

 until the current of thought changed, no longer running ex- 

 clusively upon what related to her brother, but becoming 

 capable of direction by suggestions of various kinds presented 

 to her mind, either in conversation, or, more directly, through 

 the several organs of sense.' 



I have been particular in quoting the above account, 

 because it appears to me to illustrate well, not only the 

 relation between the phenomena of dual consciousness and 

 somnambulism, but the dependence of either class of phe- 

 nomena on the physical condition. If it should appear that 

 .dual consciousness is invariably associated with some dis- 

 order either of the nervous system or of the circulation, it 

 would be impossible, or at least very difficult, to maintain 

 Brown-Sequard's explanation of the boy's case. For one 

 can hardly imagine it possible that a disorder of the sort 

 should be localised so far as the brain is concerned, while in 

 other respects affecting the body generally. It so chances 

 that the remarkable case recently dealt with by French men 

 of science forms a sort of connecting link between the boy's 

 case and the case just cited. It closely resembles the former 

 in certain characteristic features, while it resembles the latter 

 in the evidence which it affords of the influence of the 

 physical condition on the phenomena of double conscious- 

 ness. The original narrative by M. Azam is exceedingly 

 prolix ; but it has been skilfully condensed by Mr. H. J. 

 Slack, in the pages of a quarterly journal of science, I 

 follow his version in the main.
