The runways to this maze had sides which could be detached. 

 When this was done there was left a maze pattern of open, 

 elevated paths but these paths had sufficient space between 

 them so that the animals did not try to jump from one to the 

 other. It was found that on this open maze, w r here the whole 

 pattern was exposed, the visual control was not sufficient to 

 prevent there being just as real a problem as was seen in mazes 

 with enclosed sides. The situation forced the use of the feet 

 and the vibrissae in a way that the other mazes did not and 

 this fact accounts for the title at the head of this paper. Other 

 sensory elements contributed to the learning, without doubt,

but the tactual-cutaneous factors were the prominent ones and 

 the ones which we wished to throw into relief. As it is desired 

 to compare the results obtained in this w 7 ork with those secured 

 where vision and olfaction were emphasized in the Hampton 

 Court maze, let us compare the two labyrinths. 



COMPARISON OF HAMPTON COURT AND X MAZES 



The length of the true path in the Hampton Court maze is 

 40 feet, in this 17 feet. There is one more blind alley in the 

 H.C. maze than in this. The cut de sacs have a total length
