doctrine, like perhaps all the great doctrines that have come into the world, brought not peace but a sword, and had to be defended by the sword. Darwin had not the kind of disposition nor the particular faculties necessary for a deadly contest of this kind; he was interested indeed above all things in convincing a few leading naturalists of the truth of his opinions; but, that done, he would have been contented to continue his own work quietly, in absolute carelessness as to what the world in general thought of him. Huxley, on the other hand, was incapable of restraining himself from propagating what he knew to be the truth; his reforming missionary spirit was not content simply with self-defence; it drove him to be a bishop _in partibus infidelium_. By a curious and interesting accident, Huxley had the opportunity of beginning his propagandism by writing the first great review of _The Origin of Species_ in the _Times_, at that period without question the leading journal in the world. Huxley's own account of this happy chance is given in _Darwin's Life and Letters_, vol. ii. "The _Origin_ was sent to Mr. Lucas, one of the staff of the _Times_ writers at that day, in what I suppose was the ordinary course of business. Mr. Lucas, though an excellent journalist, and at a later period editor of _Once a Week_, was as innocent of any knowledge of science as a babe, and bewailed himself to an acquaintance on having to deal with such a book, whereupon he was recommended to ask me to get him out of his difficulty, and he applied to me accordingly, explaining, however, that it would be necessary for him formally to adopt anything I might be disposed to write, by prefacing it with two or three paragraphs of his own. "I was too anxious to seize on the opportunity thus offered of giving the book a fair chance with the multitudinous readers of the _Times_ to make any difficulty about conditions; and being then very full of the subject, I wrote the article faster, I think, than I ever wrote anything in my life, and sent it to Mr. Lucas, who duly prefixed his opening sentences. When the article appeared, there was much speculation as to its authorship. The secret leaked out in time, as all secrets will, but not by my aid; and then I used to derive a good deal of innocent amusement from the vehement assertions of some of my more acute friends, that they knew it was mine from the first paragraph." "As the _Times_ some years since referred to my connection with the review, I suppose there will be no breach of confidence in the publication of this little history."
