To Ernst Haeckel 20 January 
Down. | Bromley. | Kent. S.E.
My dear Sir
I thank you for your kind note of Jan. 11.1 You think much too highly of my work, but I confess it gratifies me not a little to read your frequently repeated expressions about my Origin of Species. No other photographs have been taken of me besides that published by Bronn & that by my son of which I enclose half a dozen copies.2 Do not trouble yourself to make up an equal number but I shd value greatly photographs of some of the leading naturalists in whom your country so abounds. I have only yourself Fritz Muller, Rütemeyer, & the Philolog. Schleicher.3
I am heartily glad that your book is making such good progress:4 I shall try & read it through, but it will take me an immense time, for I am a wretched German scholar & never improve. I wish I cd get it translated & will keep it in mind, but fear it will be impossible as there is but little sale for purely scientific works in England.5
I have read your account of the protogenes primordialis with much interest: nothing can be so wonderful as the vitality & movements of these fluid bodies.6 I have not yet read your larger paper on Medusæ.7 My health is better & I am now able to work one or two hours a day on the Variation of Domestic Animals & Plants; but I make slow progress.8
Pray believe me with every good wish yours sincerely | Ch. Darwin
The photographs are in a separate envelope as the postage is less—9
Sends copies of photographs of himself. Asks for photographs of German naturalists.
