Autograph letter signed with initials : London, to Thomas Richmond, 1869 Jan. 21.

Thanking him for his letter; describing his depression and deep sadness; saying that "you never can know how I have failed unless you knew what I ought to have been--and hoped to have accomplished--nor do I think you can estimate the exhaustion of hope and temper, during the disappointment of the deeper affections again and again--during thirty five years; ending at last with the fairest, longest, hope--and the most cruel sharpness of its death;" saying that he hopes "to say a few things that people won't like--nor forget--at the Royal Institution this week. Nothing does me as much good as a little row--or depresses me so awfully as forgiving my enemies."
