From A. C. Ramsay   18 June [1880]

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   20 October 1871

Summary

Glad CD agrees with his views as much as he does. Not surprised that his red rocks [Red Sandstones] ideas are disputed. The red marls of Auvergne support his inland water theory.
