page 352, 1842.); it would do you no good to lend it. I suppose I thought
that there must have been floating ice on Moel Tryfan. I think it cannot
be disputed that the last event in N. Wales was land-glaciers. I could not
decide where the action of land-glaciers ceased and marine glacial action
commenced at the mouths of the valleys.

What a wonderful case the Bedford case. Does not the N. American view of
warmer or more equable period, after great Glacial period, become much more
probable in Europe?

But I am very poorly to-day, and very stupid, and hate everybody and
everything. One lives only to make blunders. I am going to write a little

Orchids are Fertilised by Insects," London, 1862.), and to-day I hate them

he has removed all my difficulties, and that now and for evermore I give up
and abominate Glen Roy and all its belongings. It certainly is a splendid

"On the Drift and Rolled Gravel of the North of Scotland," "Quart. Journ.

convinced of the land glacialisation of Scotland before, though Chambers
