It is difficult to describe either the sounds or the gestures made on these occasions The monkey stood erect upon her feet, crossed her hands over her heart, and in the most touching and graceful manner went through a series of singular contortions. She swayed her body from side to side, turned her head in a coquettish manner, and moved her folded hands dramatically. Meanwhile her face was adorned with a broad grin, and the soft, rich notes of her voice were perfectly musical. She bent her body first into one curve and then into another, moved her feet with the grace of the minuet, and continued her fervent speech as long as the object of her adoration appeared to be touched by her appeals. Her voice ranged from pitch to pitch and from key to key, through the whole gamut of simian vocals, and with her arms folded she glided with the skill of a ballet girl across the floor of her cage. At times she stood with her eyes fixed upon her keeper, and held her face in such a position as not for a moment to lose sight of him. Meanwhile she turned her body entirely around in her tracks. This was accomplished with a skill such as no contortionist has ever attained. During these orations her eyes moistened as if in tears, showing that she felt the sentiment which her speech was intended to convey. These little creatures do not shed tears as human beings do; but their eyes moisten as a result of the same causes that move the human eyes to tears. These sounds appeal directly to our better feelings. What there is in the sound itself we do not really know, but it touches some chord in the human heart which vibrates in response to it. It has impressed me with the poetic thought that all our senses are like the strings of a great harp, each chord having a certain tension, so that any sound produced through an emotion finds a response in that chord with which it is in unison. Possibly our emotions and sensations are like the diatonic scale in music, and the organs through which they act respond in tones and semitones. Each multiple of any fundamental tone affects the chord in unison, as the strings upon a musical instrument are affected. The logical deduction is that our sympathies and affections are the chords, and our aversions the discords, of that great harp of passion.
