A few months ago, John, one of the monkeys at Lincoln Park, Chicago, was suffering from a terrible abscess on the cheek, and an operation became necessary in order to save the little fellow’s life. It was a pathetic sight to see the look of trust in the monkey’s eyes when the surgeon was ready to begin the operation, and the courage and fortitude displayed by the sufferer were almost human. At the first touch of the knife the monkey pressed his head hard against the knee of the assistant and grabbed the forefinger of each of the assistant’s hands, just as a person does who is about to undergo a painful operation. The swelling was first cut open and washed with antiseptic, when the cheek-bone was scraped and a small piece of it removed. After being again washed in antiseptic, the wound was sewed up, and John was lifted gently back into his cage—not, however, until he had licked the hands of the surgeon and kissed his face in gratitude. The little hero never uttered a sound from the time the knife first touched his face until he was put back into his cage. A similar act of intelligence is recorded of an orang. Having been once bled on account of illness, and not feeling well some time afterward, this orang went from one person to another, and, pointing to the vein in his arm, signified his desire to have the operation repeated. Both of these instances are examples of reason of a very high order—of a higher order, indeed, than many children and some grown people exhibit in similar circumstances. The chimpanzee, Mafuca, learned how to unlock her cage, and stole the key and hid it under her arm for future use. After watching the carpenter boring holes with his brad-awl, she took the brad-awl and bored holes in her table. She poured out milk for herself at meals, and always carefully stopped pouring before the cup ran over.
