From Francis Galton   9 October 1881

My dear Darwin

Pray accept my best thanks for the Worm book, which I have read, as I read all your works, with the greatest interest—& instruction.¹ I wish the worms were not such disagreable creatures to handle & keep by one, otherwise they would become popular pets, owing to your book. and many persons would try to make out more concerning their strange intelligence. Once again very best thanks, & believe me

Ever sincerely yours | Francis Galton
