Autograph Letter Signed to unnamed male correspondent.

English positivist philosopher (1831-1923). Two pages, 12mo. In poor condition: on discoloured paper with remains of stub still adhering along one edge, and with slight damage to blank verso of second leaf of bifoliate. He is obliged for the 'invitation to contribute to the pages of the International Review; & I only wish that it was in my power to accept it.' He has 'a limited amount of time for literary work' and cannot at present make 'any further engagement', but may do so in the future. Signed 'Frederic Harrison'.
