European tongue, even into such languages as Spanish, Bohemian,
Polish, and Russian. It has also, according to Miss Bird, been
translated into Japanese (Miss Bird is mistaken, as I learn from
Prof. Mitsukuri.--F.D.), and is there much studied. Even an
essay in Hebrew has appeared on it, showing that the theory is
contained in the Old Testament! The reviews were very numerous;
for some time I collected all that appeared on the 'Origin' and
on my related books, and these amount (excluding newspaper
reviews) to 265; but after a time I gave up the attempt in
despair. Many separate essays and books on the subject have
appeared; and in Germany a catalogue or bibliography on
"Darwinismus" has appeared every year or two.

The success of the 'Origin' may, I think, be attributed in large
part to my having long before written two condensed sketches, and
to my having finally abstracted a much larger manuscript, which
was itself an abstract. By this means I was enabled to select
the more striking facts and conclusions. I had, also, during
many years followed a golden rule, namely, that whenever a
published fact, a new observation or thought came across me,
which was opposed to my general results, to make a memorandum of
it without fail and at once; for I had found by experience that
such facts and thoughts were far more apt to escape from the
memory than favourable ones. Owing to this habit, very few
objections were raised against my views which I had not at least
noticed and attempted to answer.

It has sometimes been said that the success of the 'Origin'
proved "that the subject was in the air," or "that men's minds
were prepared for it." I do not think that this is strictly
