My dear Sir,

The publisher wants me to prepare the new edition of the Descent of Man as soon as possible.¹ May I ask you, if I may be able to have proofs of your new edition or if it will be better to wait, till you are ready? There is one difficulty for me personally. You know I am going again to Edinburgh for the summer session, and shall leave Leipzig about the middle of April.² If I cannot revise the translation with your corrections before I go there is very little chance for my doing it in Edinburgh, as my time is taken up there with pretty hard work almost entirely. I should therefore be very much obliged to you if you would kindly let me know, when I may be able to begin.

My health is pretty good; for, although I did not succeed to become quite free of cold, (bronchia and stomach,) yet I came through the first part of the winter better than I had been afraid. Edinburgh has done me an immense deal of good. The middle lobe of my right lung was obliterated, it became free and permeable for air again in Edinburgh So I hope that the second summer will turn out to be as beneficient as the first.

I am now very hard at work to finish my Handbook of Zoology,³ which will be done in a few weeks.

I am | Ever yours truly | J. Victor Carus
