Animal Music, its Nature and Origin. 215 
for the comparative sciences hold the keys to all ques- 
tions óf origin, and their method is simply the intelligent noting 
and collating of the facts of Nature. Allegiance to this method 
in the field of animal music has even at this early stage resulted 
in two encouraging starting points for future work—a statistical 
demonstration of the harmonic character of animal, especially 
bird, song; and a theory for the origin of melody, whether hu- 
man or extra-human, which besides the usual basis of physiologi- 
cal acoustics, employs the law of modified, inherited, selected and 
adapted structure, z. ¢., the law of evolution.
