ABSTRACT
This chapter describes Dr. Honigmann's experiment rather than hundreds of others which are constantly being made on animal behaviour. A better idea of an animal's capacity for grasping numbers comes from the experiments of the late Dr. Honigmann on hens. Honigmann made films of toads eating, and showed them to other hungry toads. Christian philosophers have usually denied that any other animals were capable of reasoning or had any rights. Darwin took the view that the higher animals possessed most of the human faculties, though many of them poorly developed. A French journalist, zealous for his country's honour, produced the story of a cat at Bordeaux which corrected the children's homework, mewing when there was a mistake in a sum and purring when it was right. Some of the more mechanistic biologists try to explain all animal behaviour on mechanical lines.
