Mr Milne divided his paper into two parts, the first comprehending a description of the leading geological features of the district; the second containing the inferences of a cosmological character, which the facts related in the first part seemed to warrant.

In describing the geology of Roxburghshire, Mr Milne referred, first, to the stratified rocks; secondly, to the igneous rocks; and, thirdly, to the superficial, or (as they have been sometimes termed) the diluvial deposits.
