point is probably much deeper than the present level of the marsh 
where the two streams take their rise, being hidden by the al- 
luvium of which this marsh forms the surface. 
Tho study of the glacial beds of this district has led MY. Wood 
to conclude, that at some time during the glacial period, the greater 
part of East Anglia over which the boulder clay had been 
deposited was converted into land, and that tho Waveney valley 
was filled by a tongue of ice, given off from the extremity of that 
portion of tho great glacial ice sheet which moved down from the 
high land of Yorkshire, through Lincolnshire, and which extremity 
rested, as he believes, in the valley of the fens. Mr. Wood main- 
tains that the filling up of tho Waveney valley by a tongue of ice 
in this way, permitted of the existence of a small glacier lake, 
similar to the Miirgolen sea in Switzerland, in the position of 
the Hoxno bed, and the waters of this lake afterwards escaping 
as tho glacier ice began to melt, caused tho excavation of the small 
lateral valley of the Goldbrook, which cuts through one side of the 
palaeolithic bed, and enters the Waveney valley at right angles near 
the village of lloxne. This theory, which claims for the Hoxne 
deposit an age intermediate between that of the first-formed portion 
of the chalky boulder clay, and that which rests on glaciated chalk 
in some of our valley bottoms, is I think worthy of consideration 
in connection with the facts discovered by Mr. Skertchly. 
Dr. James Geikie had also, previously to tho announcement of 
Mr. Skertchly ’s views, advocated in his ‘ Great Ice Age,’ the 
opinions held by himself and other geologists, that the age of 
palaeolithic man was interglacial. He has pointed out that although 
certain extinct mammalia at one time inhabited the northern parts 
of England, as proved by the occurrence of their fossil remains in 
cave deposits, such remains are not met with in the unquestionably 
post-glacial river gravels of that part of the country. The valley 
deposits in which palaeolithic implements and the bones of these 
extinct mammalia are found, are confined to the south-eastern part 
of the British Isles, and Dr. Geikie argues that their absence from 
similar beds in other parts of the country is due to the fact that all 
traces of them have been there removed by the last advance of the
