April 28th
Dear Sir
I am greatly indebted to you for your valuable present of your Heuschrecken in Südrussland & for your interesting letter.2 I have no doubt I shall find much matter of value to me in your volume; but unfortunately I am a poor German scholar & read the language with much difficulty, which has been an irreparable loss to me.— The facts which you mention in your letter in relation to the increase of mice &c from the invasion of the grasshoppers are very curious; & it is a subject which always possesses a special interest for me.3
With much respect & my best thanks, I remain | Dear Sir | Yours faithfully | Ch. Darwin
