EXPLANATIONS OF THE SECTIONS AND PLATES.

Interesting case of extensive denudation from existing causes on the northern shore of the Moray Frith. The figures and letters which mark the various beds correspond with those of fig. 5, and of the following section. The "fish-bed," No. 1, represents what the reader will find described in pp. 221-225 as the "platform of sudden death."
