d myself in an adjoining room, where I could watch the
conduct of my subject through a small hole in the door. I had a string
attached to the lever of the machine and drawn taut through another hole
in the door, so that I could start the machine at any desired moment,
and at the same time avoid attracting the attention of the monkey,
either by my presence or by allowing him to see anything move. After a
time, when everything was quiet, I set the machine in motion and treated
him to a phonographic recital by little Pedro. This speech was
distinctly delivered through the horn to Puck, from whose actions it was
evident that he recognised it as the voice of one of his tribe. He
looked at the horn in surprise and made a sound or two, glanced around
the room and again uttered a couple of sounds as he retired from the
horn, apparently somewhat afraid. Again the horn delivered some
exclamations in a pure Capuchin dialect, which Puck seemed to regard as
sounds of some importance. He cautiously advanced and made a feeble
response, but a quick, sharp sound from the horn seemed to startle him,
and failing to find any trace of a monkey, except the sound of a voice,
he looked at the horn with evident suspicion, and scarcely ventured to
answer any sound it made. When I had delivered to him the contents of
the record I entered the room again, and this seemed to afford him some
relief.

[Sidenote: PUCK'S VOICE AND ACTIONS]

A little later I adjusted my apparatus for another trial, and this time
I hung a small mirror just above the mouth of the horn. Then retiring
again from the room I left him to examine his new surroundings, and he
soon discovered the new monkey in the glass and began to caress and
chatter to it. After a while I started the phonograph again by means of
the string, and when the horn began to deliver its Simian oration it
appeared to disconcert and perplex Puck. He would look at the image in
the glass, then he would look into the horn; he would retire with a
feeble grunt and a kind of inquisitive grin, showing his little white
teeth, and acting as though in doubt whether to regard the affair as a
joke, or to treat it as a grim and scientific fact. His voice and
actions were exactly like those of a child, declaring in words that he
was not afraid, but betraying fear in every act, and finally blending
his feelings into a genuine cry. Puck did not cry, but the evidence of
fear made the grin on his face rather ghostly. Agai
