to that regular system of laws which has continued uninterrupted 
to the present day.” 
In the works of Calcott and Hutchinson,* a mass of strong 
evidence is adduced and well set forth in proof of the agency 
of diluvian currents over large portions of the surface of this 
island. 
De Saussure has recorded a valuable series of observations on 
the effects of the debacle, or breaking up and transport of rocks 
and gravel, produced by an enormous rush of subsiding waters in 
Switzerland. These effects appear to be only a larger feature of 
that same diluvian action which we have been tracing in the central 
parts of England, and which in that country are on a scale 
proportioned to the magnitude of the Alpine masses on which it 
had to exert itself. For the detail of these effects, I must refer to the 
author’s own descriptions, and also to Sir James Hall’s excellent 
paper in the Edinburgh Transactions before alluded to, in which 
he offers some most ingenious conjectures as to the probable mode 
by which the stupendous operations which have taken place in 
Switzerland were brought about. 
In Buffon’s History of the Epochs of Nature, f we find his 
description of the state of the vallies of France, and of their forms 
as derived from the excavating force of a retiring mass of waters, to 
be in perfect harmony with those of the other writers whom I have 
been quoting, and to whose observation on their own countries, 
where they had opportunities of conducting the most accurate 
investigations, I would request all persons who feel an interest in 
this subject to direct their attention.
