As monkeys discern the larger of two pieces of food, they may be said to have the perceptive faculty which enables them to appreciate dimension. As they are able to discern singular from plural, and two from three or more, they have, in that degree, the faculty of enumeration. As they are able to distinguish and select colors, they possess the first rudiment of art as dealing with color. As they are attracted or repelled by musical sounds, they may be said to possess the first rudiment of music. It must not be understood, however, that any claim is made that monkeys possess a high degree of mental culture; but it will be admitted that they possess the germs of mathematics as dealing with form, dimension, and number; of art, as dealing with form and color; of music, as dealing with tone and time. It is not probable that they have any names for any of these sensations, nor that they have any abstract ideas that are not drawn directly from experience. But as the concrete must precede the abstract in the development of reason, it is more than probable that these creatures now occupy a mental horizon such as man has once passed through in the course of his evolution. It does not require a great effort of the mind to appreciate the possibility that these feeble faculties, in constant use and under changed conditions, may develop into a higher degree of strength and usefulness. In fact we find in these creatures the embryo of every faculty of the human being, including those of reason and speech, through the exercise of which are developed the higher moral and social traits of man. They appear to have at least the raw material from which are made the highest attributes of the human mind, and I shall not contest with them the right of exclusive possession.
