A most interesting branch of this subject of the unthinking extermination of great animals by man is that of the extermination of whales. Man is worrying them out of existence. Some are already beyond saving. It would be interesting to know whether there are trypanosomes or other blood-parasites in whales. I suppose that no one has an ill-feeling towards whales. Most of us have never seen a whale, either alive or in the flesh--only a skeleton. I have seen a live whale or two off the coast of Norway; and I once, in conjunction with my friend Moseley, when we were students at Oxford, cut up one, 18 ft. long, which had been exhibited for three weeks during the summer in a tent on the shores of the Bristol Channel, where we purchased it. The skeleton of that whale is now in the museum at Oxford, but happily the smell of it exists only in my memory. The late Mr. Gould, who produced such beautifully illustrated books on birds, told me that he once fell into the heart of a full-sized whale, which he was cutting up. He narrowly escaped drowning in the blood. The whale was not very fresh, and Mr. Gould was unapproachable for a week. An immense number of whales are killed every year for their oil, and their highly nutritious flesh is wasted. There was an attempt some years ago to make meat extract from it. Some which was brought to me reminded me of the whale on the shores of the Bristol Channel. I do not know if the extract has proved palatable to other people. The Norwegians are specially expert in killing whales. They have been allowed to set up "factories" on the west coast of Ireland and in the Shetlands, where they kill whales with harpoons fired from guns, cut them up, and boil down the fat. Whales are warm-blooded creatures which suckle their young, and have been developed in past geological times from land animals--the primitive carnivora--which were also the ancestors of dogs, bears, seals and cats. Whales have lost the hind limbs altogether and developed the forelegs into fingerless flippers, whilst the tail is provided with "flukes" like the fins of a fish's tail in shape, but horizontal instead of vertical. The whole form is fish-like, the skin smooth and hairless. It is a remarkable conclusion arrived at by the investigators of the remains of extinct animals that a little four-legged creature the size of a spaniel, and intermediate in character between a hedgehog and a dog, was the common ancestor from which have been derived such widely different creatures as the whale and the bat, the elephant and the man. We can at the present day trace with some certainty the gradual modifications of form by which in the course of many millions of years the change from the primitive, dog-like hedgehog to each of those four living "types" has proceeded.
