We readily admit that popular science of a very different kind was also provided. Faraday, Kelvin, Huxley, Tyndall, Maxwell himself, did their best to make the lay public acquainted with scientific methods as well as results, to present their results as part of a coherent theory instead of as items in catalogue of marvels. But it is the marvel-mongers who have proved most tenacious of life, so that “popular” science has now become a term of contempt, and any statement whatever, provided it has the right marvellous flavour, may be printed in our newspapers as scientific information. In America such marvellous statements, not only inaccurate but meaningless, occupy pages of the Sunday supplements, so that that meritorious organ, _The Scientific American_, has to announce, in self-defence, that it publishes, not “popular” science, but merely non-technical science. In our own country that sober periodical _Nature_ used to print extracts from the more marvellous scientific items provided by the daily press, thus furnishing a little light relief from its own austere pages. The fact that this quackery exists is not unimportant. If it does no more, it often leads to a waste of time, for there has been more than one worthy gentleman who has imagined himself to be attacking the pernicious doctrines of science, when, as his argument makes clear, it is this kind of quackery he has in mind. The cure for this kind of thing would seem to be the development of a conscience in newspaper editors, unless we prefer to wait patiently until a tincture of science forms part of the education of an English adult.
