To James Croll1

Your letter2 was interesting to me as an illustration of power to seize a definite physical image—the molecules acting as hammers was capital. I have no doubt that anything you send me will interest me.3

J. C. Irons, Autobiographical Sketch of James Croll (London: Edward Stanford, 1896), p. 104

[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.
