To G. H. Darwin   24 November [1877]¹

My dear old George

I sh^d. like to sign your paper, but as it will be obvious to all on Council that I cannot judge in the least of your work,—that is whether well or ill done, & as I am your Father, my impression is that I had better not sign.—² C^d you ask Glaisher,³ if you see him?— But do whatever seems best to you. I do hope your new results will turn out good.—

Did not Thompson overlook the heat generated by the crushing & folding of the strata during the secular refrigeration of the globe, to which Mallet attributes all volcanic phenomena?— If I remember rightly Malet enters an estimation of amount of heat thus generated. This must add something to your tidal heat—⁴

Yours affect | C. D.

An Engineer M^r Read(?) of Liverpool wrote to me that he is going to publish versus Thompson about refrigeration of globe.—⁵

The more I think the more I am inclined to believe I had better not sign.—
