Introduction--General ignorance on the subject of evolution at the time the "Origin of Species" was published in 1859.

There are few things which strike us with more surprise, when we review the course taken by opinion in the last century, than the suddenness with which belief in witchcraft and demoniacal possession came to an end. This has been often remarked upon, but I am not acquainted with any record of the fact as it appeared to those under whose eyes the change was taking place, nor have I seen any contemporary explanation of the reasons which led to the apparently sudden overthrow of a belief which had seemed hitherto to be deeply rooted in the minds of almost all men. As a parallel to this, though in respect of the rapid spread of an opinion, and not its decadence, it is probable that those of our descendants who take an interest in ourselves will note the suddenness with which the theory of evolution, from having been generally ridiculed during a period of over a hundred years, came into popularity and almost universal acceptance among educated people.

It is indisputable that this has been the case; nor is it less indisputable that the works of Mr. Darwin and Mr. Wallace have been the main agents in the change that has been brought about in our opinions. The names of Cobden and Bright do not stand more prominently forward in connection with the repeal of the Corn Laws than do those of Mr. Darwin and Mr. Wallace in connection with the general acceptance of the theory of evolution. There is no living philosopher who has anything like Mr. Darwin's popularity with Englishmen generally; and not only this, but his power of fascination extends all over Europe, and indeed in every country in which civilisation has obtained footing: not among the illiterate masses, though these are rapidly following the suit of the educated classes, but among experts and those who are most capable of judging. France, indeed--the country of Buffon and Lamarck--must be counted an exception to the general rule, but in England and Germany there are few men of scientific reputation who do not accept Mr. Darwin as the founder of what is commonly called "Darwinism," and regard him as perhaps the most penetrative and profound philosopher of modern times.

To quote an example from the last few weeks only, [2] I have observed that Professor Huxley has celebrated the twenty-first year since the "Origin of Species" was published by a lecture at the Royal Institution, and am told that he described Mr. Darwin's candour as something actually "terrible" (I give Professor Huxley's own word, as reported by one who heard it); and on opening a small book entitled "Degeneration," by Professor Ray Lankester, published a few days before these lines were written, I find the following passage amid more that is to the same purport:-

"Suddenly one of those great guesses which occasionally
