254 THE HORSE OF MR. VON OSTEN 



were some cases in which the questioner did not know 

 the correct solution of the problem or was mistaken about 

 it. And lastly, several of the undersigned have become 

 acquainted with the method which Mr. von Osten used, 

 which has little in common with methods of training, and 

 is patterned after the instruction given in the elementary 

 schools. As a result of these observations the under- 

 signed are of the opinion that unintentional signs of the 

 kind which are at present familiar, are likewise excluded. 

 They are unanimously agreed that this much is certain: 

 This is a case which appears in principle to dififer from 

 any hitherto discovered, and has nothing in common with 

 training, in the usual sense of that word, and therefore 

 is worthy of a serious and incisive investigation.
