his translation contains long and important passages which are not in
the February number of Kosmos, while many passages in the original
article are omitted in the translation.

Among the passages introduced are the last six pages of the English
article, which seem to condemn by anticipation the position I have
taken as regards Dr. Erasmus Darwin in my book, "Evolution, Old and
New," and which I believe I was the first to take. The concluding,
and therefore, perhaps, most prominent sentence of the translation
you have given to the public stands thus:-

"Erasmus Darwin's system was in itself a most significant first step
in the path of knowledge which his grandson has opened up for us, but
to wish to revive it at the present day, as has actually been
seriously attempted, shows a weakness of thought and a mental
anachronism which no man can envy."

The Kosmos which has been sent me from Germany contains no such
passage.

As you have stated in your preface that my book, "Evolution, Old and
New," appeared subsequently to Dr. Krause's article, and as no
intimation is given that the article has been altered and added to
since its original appearance, while the accuracy of the translation
as though from the February number of Kosmos is, as you expressly
say, guaranteed by Mr. Dallas's "scientific reputation together with
his knowledge of German," your readers will naturally suppose that
all they read in the translation appeared in February last, and
therefore before "Evolution, Old and New," was written, and therefore
independently of, and necessarily without reference to, that book.
