The violent stranding of floating ice as first mentioned in CD’s article ["Ancient glaciers of Caernarvonshire", Collected papers 1: 163–71] is the most remarkable of the Moel Tryfan phenomena.

Has found three zones of stones in the Welsh and Pennine mountains which he accounts for by elevation and subsidence. Does CD think that these movements in historical times have been caused by earthquakes or by slow and gradual movements?

The use of earthquakes as a geological cause in his previous letter was careless.

Shelly beach deposits over considerable distance from Ireland to Scotland seem better explained by high sea-level than low land.

Only CD seems to have reported shattered rocks under the Moel Tryfan drift.

Thanks for the American pamphlet, which has caused him to write the enclosed extract on "bent and shattered edges of slaty laminae".

Asks for CD’s opinion on certain theistic ideas. If spontaneous generation from inorganic material is denied, then life must be derived from some eternal being.
