Autograph letter signed : Camden, New Jersey, to Dr. S. Weir Mitchell, 1890 Apr. 30.

Thanking him for $100 received through Horace Furness for a manuscript copy of his poem "O Captain! My Captain": "Dear Doctor / Your splendid contribution to me has been rec'd by the hands of Horace Furness & is hereby deeply thank'd for ($100) It is opportune & will do me much good. / I send a copy of my Complete Works & some pictures--with a slip of little piece in May _Century_--& my best respects, love & thanks--am just getting over the worst of a two months' siege of the grip--bad enough yet--get out in a wheel'd chair--shall probably get out this afternoon--God bless you Doctor-- / Walt Whitman."
