My dear Mr Appleton
I am very much obliged to you for your kind note & wish to aid my heretical transmutation doctrines.2 I hope you will be so good as to give my sincere thanks to Mr C. C. Fuller for all the trouble which he has taken.3
The creature I am sorry to say is not a fish; but the larva of some Batrachian or Frog-like animal.
I have sent the specimen to the British Museum where they are glad to have it for they have nothing exactly the same, but tell me that it is closely allied to the Axoltl of Mexico & to the Mud devil of the lakes of N. America.4
We often remember the very pleasant visit you paid us many years ago, & sincerely wish it cd be repeated.5
My wife joins in very kind remembrances to you & I remain | my dear Mr Appleton | yours very sincerely | Charles Darwin
