[January]: according to the Autobiographical Sketch of James Croll (p. 104), this was a response to a letter from Croll in early 1863.
Your letter: letter missing.
anything you send me will interest me: in early 1864 Croll sent Tyndall a paper which Tyndall published in the Phil. Mag. See letter 2072.
