Sherrington, by experiments on dogs, showed that many of the usual marks of emotion were present in their behaviour even when, by severing the spinal cord in the lower cervical region, the viscera were cut off from all communication with the brain, except that existing through certain cranial nerves.

And, unlike the mere bush dogs, who stole shelter from the rain under overhanging eaves, Jerry was given a dry place under the roof where the heads of bushmen and of forgotten sandalwood traders hung down from above in the midst of a dusty confusion of dried viscera of sharks, crocodile skulls, and skeletons of Solomons rats that measured two-thirds of a yard in length from bone-tip of nose to bone-tip of tail.
