it appears, was not because I bad objected to a 

 certain numerical statement about discord, but 

 because I had referred to a curve by the late 

 Professor Mayer which Mr. Meyer considers 

 worthless. The work of Helmholtz in the same 

 domain he also considers worthless. He quotes 

 Melde and Stumpf, who differ with Mayer and 

 Helmholtz. He concludes by saying "Upon 

 the cause of discord the psychologists have not 

 agreed ; it is yet unknown — at least to the psy- 

 chologists." 



For many years I have been convinced that 

 beats do not constitute the sole cause of dis- 

 cord, but that probably they constitute one 

 efficient and important element. So far as this 

 may be admitted, Mayer's curve is the nearest 

 approach to an expression of facts within the 

 range he selected. The present controversy 

 seems to be chiefly regarding authorities. 

 Criticism intended to be destructive is not a 

 substitute for constructive evidence. The opin- 

 ions of Melde and Stumpf are of course worthy 

 of respect, but they do not prove Helmholtz 

 and Mayer to be wholly wrong. It does not 

 seem to me that the subject is of sufficient im- 

 portance to call for further discussion.
