18 Oct 1871
My dear Sir
I send two papers which contain some new views which if true may have considerable bearing on the long continuance of generic & specific terrestrial types as opposed to Marine.1
In the Summary of No 2 I attempt to show that we had in Europe & elsewhere great continental areas that lasted from the close of the Upper Silurian epoch down to the beginning of the Lias, & in earlier paragraphs I try to prove that some of the strata usually called marine were in reality formed in old Caspians.2
Yours very truly | Andw C Ramsay
