Ahoy there captain...you're looking might spry for being 130 plus years old.

Nature Magazine has an amazing search feature -

I cannot find your letter anywhere.

Much less in one from the 1870's - your reference noted above. - NATURE, vol. xxii. p. 76

Might say - you are a true phenomenium of Nature - never having a last good-bye....so to speak.
