ivered them to the female, who showed some signs of interest, but
the record was very imperfect and her manner seemed quite indifferent.
In this experiment, for the first time in the history of language, was
the Simian speech reduced to record; and while the results were not
fully up to my hopes, they served to inspire me to further efforts to
find the fountain-head from which flows out the great river of human
speech. Having satisfied myself that each one recognised the sound made
by the other when delivered through the phonograph, I felt rewarded for
my labour and assured of the possibility of learning the language of
monkeys. The faith of others was strengthened also, and while this
experiment was very crude and imperfect, it served to convince me that
my opinions were correct as to the speech of these animals.

[Sidenote: RECORDS OF SOUNDS]

In this case I noticed the defects which occurred in my work and
provided against them, as well as I could, for the future. Soon after
this I went to Chicago and Cincinnati, where I made a number of records
of the sounds of a great number of monkeys, and among others I secured a
splendid record of the two chimpanzees contained in the Cincinnati
collection, which I brought home with me for study. The records that I
made of various specimens of the Simian race I repeated to myself over
and over, until I became familiar with them, and learned to imitate a
few of them, mostly by the use of mechanical devices. After having
accomplished this I returned to Chicago, and went at once to visit a
small Capuchin monkey whose record had been my chief study. Standing
near his cage, I imitated a sound which I had translated "milk," but
from many tests I concluded it meant "food," which opinion has been
somewhat modified by many later experiments which led me to believe
that he uses it in a still wider sense. It is difficult to find any
formula of human speech equivalent to it. While the Capuchin uses it
relating to food and sometimes to drink, I was unable to detect any
difference in the sounds. He also seemed to connect the same sound to
every kindly office done him, and to use it as a kind of "Shibboleth."
More recently, however, I have detected in the sound slight changes of
inflection under different conditions, until I am now led to believe
that the meaning of the word depends somewhat, if not wholly, on its
modulation. The phonetic effect is rich and rather flute-like, and the
word rese
