To Gustav von Leonhard1 20 March 
Down Farnborough | Kent
Dear & much respected Sir.
I cannot resist writing to thank you for your kindness in sending me a copy of your review2 of my Volcanic Islands, & for the very great honour which you have done me in your manner of speaking of it.— It is no small satisfaction to me, to reflect that my small work has been thought worthy of careful perusal by a name, which I have for so many years known & honoured.
I have taken the liberty to direct my publishers to transmit to you a copy of my S. American volume and I trust you will accept it as a trifling acknowledgment on my part of your kindness.3
With my most sincere respect, I beg, dear Sir, to remain | Your faithful & obliged sevt. | Charles Darwin
Honoured by GL’s review of Volcanic islands.
Sends copy [of South America].
