My dear Sir,

During the present bookseller-fair Mr Koch (Schweizerbart) called here and told me, that a new edition of the translation of the “Origin” would be necessary, to be published in the first part of next year. He intends to begin the printing of it in October next. As far as I know there has not been a new edition of that work in England since 1866.¹ Should it have been the case I should be sorry to have overlooked it. At all events I beg to take the liberty of asking your kind help as in the last edition. If you wish to make any alteration or to give some additions you would oblige me exceedingly if you would kindly prepare them so that I may be able to begin the revision and reworking in September. I am afraid I shall not have time to look to it before that time as I am bound to finish my ‘History’ within the next months.²

The Variation under Domestication has also been sold very well.³ As it is rather expensive for German purses, it is no wonder that the whole of the edition has not yet been sold. But I think it always a very good result, that two thirds of the edition are gone, as Mr Koch tells me. I hope we shall have a new edition in 1871.⁴ Mr Koch also asked me, if any of the works were out which you mention in the Introductory Chapter of the Variation⁵   I know that is not the case, as you wrote me you were busy on man.⁶ When this new work of yours will be ready I should be happy if you would allow me to bring it before the German public. Mr Koch, too, makes a point of it to publish your works. Of course I could not speak with him positively about it, as I don’t know what you intend. But I must say it would be very kind of you if you would think of us, if you intend at all to have it translated.⁷

I hope your health is better than it was when I heard last of you.

Believe me | My dear Sir | Yours very sincerely | J. Victor Carus
