Extract

In the Magazine for December I gave a brief outline of certain phenomena connected with the Scottish Till, the chief aim of my paper being to insist that beds of clay, sand, and gravel frequently occur in that deposit, and that we can no longer consider these as either insignificant or accidental.

page 29 note 1 I think it much to be desired that the terms Till and Boulder-clay should not be applied to one and the same deposit. If Till were taken to mean simply the material collected underneath land-ice, the moraine profonde of Swiss geologists, it would save confusion. Boulder-clay could then be applied to those more or less stratified clays with boulders which have been deposited in water. In my previous paper I have used the two terms interchangeably; in the present paper, however, and in future, I will apply them in the manner just suggested.
