The paper then entered upon a discussion of the direct frigorific 
effects of such an immense plateau, composed of such material, con- 
trasting it with a similar plateau of bare earth, and applying to it 
various meteorological considerations, all tending to show that in the 
interior of such a plateau an intensely cold climate would continue 
through the year. 
Application was made of basic considerations to the question of a 
d ove 
the retreat of the china. By the cae motion the ‘dewtenn is trans- 
Ported over limited distances. For the remote transportation of 
drift, the agency of icebergs and ice-rafts is necessary. This latter 
Point is discussed in the paper on the Ripton Sea-beaches. 
“The Ripton Sea-beaches,” by Professor E. Hungerford. This pa- 
per gives a somewhat detailed description of a series of terraces, 
present position and form. The configuration of the country being 
rded as unfavorable to the accumulation of a large body of fresh 
water at this point, these deposits are cited as a strong confirmation 
2,000 feet beneath the sea since the glacial epoch proper. 
The author of the paper took occasion to concisely present his 
ena. The geological events enumerated succeeded each other in the 
ae order :— 
. The formation of a continental glacier to whose partial m 
sine; always limited to a comparatively narrow belt upon the ati 
ern or seaward margin, are due the erosive phenomena, and the trans- 
_ portation of the drift over limited areas.
