154 THE SPEECH OF MONKEYS. 



the vocal apparatus of man or animal. The 

 sounds from which I have developed such results 

 were neither vowel nor consonant as those sounds 

 are defined, but simply prolonged musical notes. 

 In another chapter will be found some of the 

 experiments which I have performed with the 

 phonograph in the investigation of sounds of va- 

 rious kinds. If I am allowed to think for myself 

 at all, I am not ready to accept as final some of 

 the dogmas on the theory of sound which have 

 long been held and taught, and many of which 

 remain orthodox for no other reason than that no 

 one has denied them. I am not ready at this 

 point to spring upon the world any new theory 

 of sound, but I am quite ready to refuse to be- 

 lieve some of the tenets set forth in the creeds 

 of philology. Heresy is the author of progress, 

 and I confess myself a heretic on many of the 

 current doctrines of the science of sounds.
