DUAL CONSCIOUSNESS. 273 



formed a properly written and corrected letter. Immedi- 

 ately after he had written his letter, F. got up, walked down 

 to the garden, made himself a cigarette, lighted and smoked 

 it. He was about to prepare another, but sought in vain 

 for his tobacco-pouch, which had been purposely taken 

 away. The pouch was now thrust before his eyes and put 

 under his nose, but he neither saw nor smelt it ; when, how- 

 ever, it was placed in his hand, he at once seized it, made 

 a fresh cigarette, and ignited a match to light the latter. 

 The match was blown out, and another lighted match 

 placed close before his eyes, but he made no attempt to 

 take it ; and if his cigarette was lighted for him, he made 

 no attempt to smoke. All this time his eyes were vacant, 

 and neither winked nor exhibited any contraction of the 

 pupil.' 



These and other similar experiments are explained by 

 Dr. Mesnet (and Professor Huxley appears to agree with 

 him) by the theory that F. 'sees some things and not 

 others ; that the sense of sight is accessible to all things 

 which are brought into relation with him by the sense of 

 touch, and, on the contrary, insensible to all things which 

 lie outside this relation.' It seems to me that the evidence 

 scarcely supports this conclusion. In every case where F. 

 appears to see, it is quite possible that in reality he is guided 

 entirely by the sense of touch. All the circumstances 

 accord much better with this explanation than with the 

 theory that the sense of sight was in any way affected. Thus 

 the sunlight shining through the window must have affected 

 the sense of touch, and in a manner similar to what F. had 

 experienced when before the foot-lights of the stage, where 

 he was accustomed to appear as a singer. In this respect 

 there was a much closer resemblance between the effect of 

 sunlight and that of the light from footlights, than in the 

 circumstances under which both sources of light affect the 

 sense of sight. For in one case the light came from above, 

 in the other from below ; the heat would in neither case be 

 sensibly localised. Again, when a screen was interposed
