134 Journal of Comparative Neurology. 



Dr. Clark reported that experimental study of the pressure sense 

 in the human skin gave the same sensations for traction as for pressure. 

 In hairless regions of the body these sensitive areas are often widely 

 separated. 



Professor Herrick in discussing the theory of nerve components 

 pointed out the advances already made by this means of study and out- 

 lined the problems which may be solved by it in the future. The com- 

 parison of the lateral line systems of different fishes by Miss Clapp 

 showed the common plan of distribution of the nerves and sense or- 

 gans in widely different groups. 



Since the papers presented were confined to original contributions, 

 rather than reviews, only about half of those engaged in neurological 

 work took an active part, except in the discussions, their work not be- 

 ing in shape to report.
