C. J. Cornish,
Life at the Zoo: Notes and Traditions of the Regent's Park Gardens
“ Setting up its huge, flapping ears, it flung up its trunk, snorted and whistled like a steam-engine, driving its head against the rails, and exhibiting every mark of anger and dislike. The Indian bison and the gayal both brought forward their broad ears to listen, and, resting their muzzles against the railings, seemed to enjoy the sounds; a sharp discord caused them to start back, and produced the same effect on the zebras and African wild ass, both of which listened to the harmonious chords with pleasure, and followed the musician from one side of their stall to another. ”
