From A. C. Ramsay   18 August 1864

My dear Mr Darwin

You read about that lake that was to be drained in my “Old Glaciers of North Wales”.¹ The lake is Glaslyn on Snowdon. It never was done.

I hope you have read or will read Sir Rodericks counterblast against my theory in his Anniversary Address to the Geographical Society.² If authority can squash a man I am squashed; but I am contumacious enough to think that such a method will not advance his reputation. I think I must answer it, even though I feel that any reply however good cannot have any effect on any one who can accept Sir Rodericks assertions as arguments.³

At Beaumaris⁴ I finished my “Geology of North Wales”, and am about ready to go to Press.⁵ It is essentially Silurian, & I touch nothing later than the New Red Sandstone.

Ever sincerely | And^rew C Ramsay
