To Ludwig Rütimeyer 4 May 1
Down. | Bromley. | Kent. S.E.
My dear Sir
I am very much obliged to you for your never failing kindness in sending me so many of your works, which I have long esteemed as of the highest value.2 I am now correcting the proof sheets of a work on the variation of domestic animals & plants, & in this I have a short chapter on pigs, cattle &c; it contains no original matter & is compiled largely from your works; but this chapter has now been printed, & therefore I shall not be able to improve it from any facts contained in the second part of your work on cattle which I have just received.3
Prof. Victor Carus is going to translate my book into German & I will send you a copy when it is published, which I suppose will be towards the close of this year; but I fear there will not be much in it that will interest you.4
With my sincere thanks | believe me my dear Sir | yours very faithfully | Ch. Darwin
