Mr. Wallace also succeeded in finding a baby orang-outang, and gives his experience with it as follows:
This account is interesting, because it shows that in its actions the young orang-outang recalls what we are familiar with in infants; and again it illustrates the activity of the limbs at an early age and before they can be used intelligently.
