My dear Tyndall

I write a single line to say that it was not of the least consequence your retaining the letter for as long as you liked.— I shall be most happy at any time to send you the letters again, if you like to publish any passages.—

We are all here idling for health-sake & enjoying the beautiful scenery & sea air—

By the way the other day at dinner we were all sticking bits of ice together by their points, marvelling at the phenomenon & talking of you—

Yours most sincerely | Ch. Darwin

    The year is given by reference to the Darwins' stay in Torquay during the summer of 1861 (see `Journal'; Appendix II).

    The reference is to letters from Erasmus Darwin to Josiah Wedgwood I that CD had sent to Tyndall (see letter to John Tyndall, 23 February [1861], and Correspondence vol. 9, Appendix V). The letters discussed physical aspects of the congelation of ice.

    Tyndall used the principle of `regelation' to account for the way in which a glacier could be moulded under its own pressure. According to this principle, when ice is broken into fragments under pressure, the fragments, becoming moist through melting, reunite when they again come into contact. See Tyndall 1860, pp. 351--2.
