To G. D. Hinrichs   16 September 1868

Dear Sir

I am much obliged for your letter of Aug 31. & for your various works received safely.¹

Although much obliged for your kindness, I am sorry that you have sent your works to me, as, though with the best will to aid you, I have not the power. I am much out of health, never attend scientific meetings, rarely go to London & seldom see any scientific men.

I believe Prof. Tyndall is not now in London, but towards the end of the month I will write to him & endeavour to interest him in your publications.² He will I dare say distribute some of your circulars & I will send off some others. With respect to the publication of your new book in England & receiving profit from it, I feel sure that, until your name is generally known, it is entirely out of the question.³ I feel sure of this from my communications in similar cases with M^r Murray⁴

I wish I could be of more use to you but this under my circumstances is impossible.

I can only wish you success & remain dear Sir | yours faithfully | Ch. Darwin
