THE FOURTH DIMENSION 12$ 



humanity of the present will merge itself into a new race, 

 endowed with new senses, whose revelations are to us, for 

 the present, at least, utterly inconceivable. 



The possibility of such a development may be rendered 

 more clear if we imagine the existence of a race devoid of 

 the sense of hearing, and without the organs necessary to 

 that sense. They certainly could form no idea of sound, 

 far less could they enjoy music or oratory, such as afford 

 us so much delight. And, if one or more of our race should 

 visit these people, how very strange to them would appear 

 those curious appendages, called ears, which project from 

 the sides of our heads, and how inexplicable to them would 

 be the movements and expressions of intelligence which we 

 show when we talk or sing ? It is certain that no devel- 

 opment of the physical or mathematical sciences could give 

 them any idea whatever of the sensations which sound, in 

 its various modifications, imparts to us, and neither can any 

 progress in that direction enable us to acquire any idea of 

 the revelations which a new sense might open up to us. 

 Nevertheless, it seems to me that the development of new 

 senses and new sense organs is not only more likely to be 

 possible, but that it is actually more probable, than any 

 revelation in regard to a fourth dimension.
