The noise he made irritated and disturbed me, and I rose in my chair and called him by name, somewhat angrily.

He paused in his game and looked up--his eyes met mine exactly.

His head drooped; he shivered uneasily, whined, and lay down motionless.

He never stirred once from the position he had taken, till I gave him permission--and remember, he was untrained.

This strange behaviour led me to try other experiments with him, and all succeeded.
