THINKING ANIMALS 16? 



others of a similar nature may be eventually classified. 

 It will be sufficient for me at present to group the 

 performances of the animals, if possible, with something 

 better known. And " mediumistic " facts, extrinsi- 

 cally at least, are certainly better known. I refer 

 therefore to them as I find them described in the 

 psychology called supernormal ; because, from force 

 of circumstances I am compelled to recognize that 

 it is within this psychology that I must now continue 

 the discussion.
