236 The American Naturalist. [March, 
So the great law of the equilateral triangle, which Dr. Bonwill 
has discovered, and ranks beside the immutable law of gravita- 
tion, and which he believes impossible save by a special creation, 
bids fair to be undone by man himself, and to be superseded 
through civilization by a jaw of greater anterior angle and of 
broader base. 
INSTANCES OF THE EFFECT OF MUSICAL SOUNDS 
ON ANIMALS. 
BY R. E. C. STEARNS. 
(Continued from page 130.) 
ANOTHER anecdote relating to 
PIGEONS AND MUSIC 
is recorded by Goodrich. 
“ Bertoni, a famous instructor in music, while residing in 
Venice, took a pigeon for his companion, and, being very fond of 
birds, made a great pet of it. The pigeon, by being constantly 
in its master’s company, obtained so perfect an ear for music that 
no one who saw his behavior could doubt for a moment the 
pleasure it took in hearing its master play and sing.” 
The Rev. Mr. James also furnished us with the following : 
“T have a canary of the feminine persuasion who is particu- 
larly fond of music. Immediately I begin to play upon the flute 
she chirps about as if enjoying the music. If I open the cage- _ 
door and leave her, she will come as near to me as possible, but 
not attempt to fly to the music; but if I put her upon my desk, 
and lay the flute down, she will perch upon the end, and allow 
me to raise the instrument and play. I often take her into the 
church and play there upon the organ, and she will perch upon 
my fingers,“notwithstanding the inconvenience of the motion of 
the hands, and chirp in evident delight at the sweet sounds.”
