698 APPENDIX. 



clusively opposed to the notion of Wundt, Bain and Lewes, and to 

 others who may hold that any part of our notions concerning 

 degrees of ' resistance ' are derived from the volitional or motor 

 centres. A case of this kind was long ago recorded by Demeaux*". 

 some details of which are well worthy of being cited. There was 

 a complete loss of sensibility (both superficial and deep) ia 

 the moving member, and Demeaux says: — "She put her muscles 

 in action under the influence of her will, but she had no con- 

 sciousness of the movements which she executed ; she knew not 

 what was the position of her arm — it was impossible for her to say 

 whether it was extended or flexed. If one told the patient to raise 

 her hand to her ear, she executed the movement immediately; but 

 when my hand was interposed between her own and the ear, she 

 was not conscious of it ; if I stopped her arm in the midst of its 

 movement, she did not become aware of it. If I fixed, without 

 allowing her to be aware of it, her arm upon the bed and told her 

 to raise the hand to her head, she strove for an instant and then 

 became quiet, believing that she had executed the movement. If 

 I induced her to try again, showing her that her arm had remained in 

 the same place, she attempted to do so with more energy, and as 

 soon as she was compelled to call into play the muscles of the 

 opposite side [of the body], she recognized that the movement was 

 opposed." 



In the recent contribution of G. H. Lewes to this subject, he 

 brings forward no new arguments against the possible exclusive 

 adequacy of passive sensibilities, and he now largely admits them 

 as components of the complex group of impressions resuliinq from 

 movements which go to make up what is known as the 'Muscular 

 Sense.' And except that he holds to the doctrine that some active 

 sensibilities enter into the same complex, his present views are 

 almost entirely in accordance with those expressed by the writer, in 

 the paper above referred to. The evidence which Lewes considers 

 favourable to the existence of an ' active ' element in the ' muscular 

 sense' endowment, can, in the writer's opinion, be better explained 

 by the supposition previously started, and still favoured by him, 

 that a set of * unfelt ' impressions relating to states of tension of 

 muscles exists— the components of which are more or less distinct 

 from those that revoal themselves in consciousness. 



The writer, for instance, pointed out in 1869 that in ' locomotor
