From Andrew Crombie Ramsay 21 February 1860

Summary

ACR has for years had a belief in mutability and transmutation of species, prompted by disputes over the nature of species and varieties, and the existence of representative species in space and in the geological record. Could not accept a Creator employing small miracles to make species differ just a little between formations. Has maintained that one would not expect to find fine gradations between forms in the fossil record, but only representatives of very populous forms. [See 2711.]

From A. C. Ramsay   26 August 1862

Sends his paper [on glacial lakes, see 3450]. Falconer attacked it. Falconer thinks Himalayas confound the theory, but Hooker writes that it explains the absence of lakes there.
