206 BRECCIAS AND THE PHYSICAL GEOGRAPHY OF THEIR AGE. [ May 1902, 
reference had been made. That the Sutherland district had been 
affected by earth-movements during the formation of the breccias 
was indicated by certain sandstone-dykes. 
The AvrHor, in replying, said that he fully accepted Mr. Wickham 
King’s view of the origin of the Clent breccias, but thought the word 
‘uplands’ preferable to ‘ highlands’ for the district which had sup- 
pied the materials. Where denudation was subaérial, any ‘planing- 
down’ would be slow work. Charnwood was too distant to be 
quoted in support of the term ‘highlands.’ As for the origin of the 
Flysch, the Diablerets district was doubtless folded and faulted ; but, 
as it was fairly dissected, surely the crystallines which had supplied 
the materials (as Prof. Lapworth suggested) ought to have been some- 
where exposed. Those great foldings also were of later date than 
the Flysch. ‘The point mentioned by Prof. Watts about the present 
landslip-zone in Switzerland was very interesting, but the material 
of the breccias hardly corresponded with that of the landslips which 
the Author had examined. In reply to Prof. Seeley’s complaint 
that he had not included conglomerates in his paper, he had already 
written a fair amount about them, and thought that an Author had a 
right to choose his own subject. As to the complaint of brevity, 
he had studied that in his paper, because he wished to summarize, 
not to reprint, and on this occasion further condensation had been 
made necessary by no fault of his. The occurrence of footprints in 
association with the Dolomitic Conglomerate, which he feared had 
slipped his memory, was an interesting fact.
