My dear Darwin
Whitworth has sent us £150— so that we have got clean over the the 2000—1
I have sent the money on to Lubbock who will do what is right with it.2
Don’t be fainthearted—no purer aim or object ever animated a man than that which animates you.3
Kind regards to Mrs. Darwin | ever & always yours | John Tyndall
Huxley has returned. I wish I could persuade you & Huxley to join Everyone at luncheon here on Wednesday4
