down what vowel each impression seemed to him to rep- 

 resent. 



(3) The subject and experimenter checked up and the 

 experimenter repeated the series for drill. 



(4) After this a new unknown series was presented. 

 Beginning with the 20th each vowel in the series of 



10 was pronounced three times instead of once. Other- 

 wise the method remained the same as before. This 

 modification of procedure is apparently producing good 

 results. 



Experience up-to-date satisfies me that it is possible 

 to learn to interpret oral speech by tactual impressions. 

 I have not yet made a learning curve for each vowel. 

 I is most easily learned with A and close seconds. E 

 and U are easily confused. As nearly as I can describe 

 the criteria they are as follows: 



A is a long, heavy, steady impression. 



E is long and steady, but not so heavy as A. 



I gives two impressions. The first is quick and 

 sharp. The second is prolonged, rather heavy and 

 smooth. 



has a roll about it that may be mistaken for two 

 distinct impressions such as I affords. 



U is short, light, and smooth.
