Dear Sir

You are perfectly welcome to translate the paper, (of which I send separate copy by this post) if on further reflexion you think it worth while, but really it hardly appears to me deserving of the honour. Moreover translations have already appeared in the Cologne Gazette & in another German newspaper..—²

I am extremely glad to hear that Kosmos succeeds fairly well.— Several of the articles have interested me much, & I believe almost all would have done so, if I did not find German so difficult to read.³

The discussion written I suppose by you on the sense of colour having been acquired within a recent period seemed to me very curious, & I wrote a short letter to you in regard to what had struck me with respect to my own infants’ power of distinguishing or rather naming colours.— I wrote this when away from home, & forgetting your address addressed it to the care of the publisher of Kosmos, Herr Günther in Leipzig.— It was only a short note of no value.—⁴

With many thanks, I remain Dear Sir | Yours faithfully | Ch. Darwin
