My dear Sir.

I thank you cordially for your most kind letter, which tells me everything I wished to learn—¹ I have written to Herr Würtenberger by this post, offering to send him a sum of money, which with economy would allow him to work for about a year on science; but whether he will accept it, I cannot of course say.—² I have told him of your most generous offer to aid him with information references &c, if he will communicate with you.—

I am delighted to hear of your work on the Lower Liassic fossils; it is a most interesting geological stage & I feel sure that your manner of considering chiefly the forms which are closely allied will throw a flood of light not merely on Geology but on the whole Descent Theory.³

Again thanking you cordially, | I remain with much respect. Yours very faithfully— | Charles Darwin.
