Here he is at Birmingham, asking for money, and hinting that, unless all experiments on animals are stopped, _the poor will be the ultimate victims_. Here, at Gloucester, saying that _it is silly to experiment at all_, and that he is not going to take his views as to right and wrong from any man of science, however learned he may be. Here, at Edinburgh, with the _Closed Doors_ again, and the picture of the rabbit "roasted alive": three grains of opium, he tells them, would be enough to kill the strongest navvy in Edinburgh, but 16 grains can be administered to a pigeon; and the death-rate has gone up every year in spite of vivisection. Here, at a drawing-room meeting, asking for money; here, at a garden party, with a _considerable number of persons ranging themselves on the grass_, and he tells them that they have on their side all that is best in every department of public life; here, at Blackburn, with the _Closed Doors_ again, calling the law _a sham and a farce_; here, at Cheltenham, with Bishop Mitchinson in the chair, still quoting the Registrar-General, and saying that _he does not think the outlook was ever more promising than it is to-day_. All over the kingdom, he and his magic-lantern, year after year, goes Mr. Wood. He is a fluent speaker; he has things in his pocket; they are brought out, if you contradict him; or he "challenges" you, or explains you away, or says that you "are not quite playing the game." Let him alone; to-morrow he will pack up his lantern, and be gone. Mr. Coleridge, in his use of the death-rate argument, carries it even further than Mr. Wood; for he applies it over a wider range. "Look at myxoedema," he says; "the doctors tell us that they can cure it with thyroid extract, and that the use of thyroid extract was discovered by the help of experiments on animals. Very good. Myxoedema is due to some fault in the thyroid gland. Very good. But here are the Registrar-General's returns of the annual death-rate for all diseases of that gland. See, the death-rate has gone up, steadily, during the last 20 years." Was there ever such an argument? It is only of late years that myxoedema has been generally recognised. Till it was recognised, it was not diagnosed; till it was diagnosed, it was not returned as a cause of death. Again, there are many other diseases of the thyroid gland, including various forms of malignant disease. It is cancer of the thyroid gland that decides the death-rate. The number of deaths from myxoedema, especially since the discovery of thyroid extract, must be small indeed. Moreover, apart from Mr. Coleridge's fallacy of argument, it is impossible to see how he can really doubt the efficacy of the thyroid treatment, both in myxoedema and in sporadic cretinism.
