Notes and Comments. 217 
THE AGE OF MOORLOG. 
With regard to Dr. Munthe’s opinion that the age of the 
Moorlog may possibly be ‘interglacial,’ on this point we 
respectfully beg to differ. We are by no means sure of evidences 
of a mild interglacial period, so far as the beds exposed in 
East Yorkshire indicate, and certainly a careful examination 
of the Moorlog, its underlying clay, and their botanical and 
zoological contents, give no such indications; in fact all 
point to the deposits being of post-glacial date. 
POST-GLACIAL CLIMATIC CHANGES. 
Bearing upon this most interesting topic, we should like 
to draw attention to a valuable work, ‘ Die Veranderungen des 
Klimas seit dem maximum der Letzten Eiszeit’ (‘ Climatic 
Changes Since the Last Ice Age’), a collection of papers read 
before the Committee of the Eleventh International Geological 
Congress at Stockholm, and sold for a severeign .by General- 
stabens Litografiska Anstalt, Stockholm (lviii.+459 pp.. 4to). 
In this are given reviews of the subject, by various authorities, 
covering all parts of the world, and some of the more interesting 
are printed in English. 
ENGLISH EVIDENCE. 
For ‘ Gross-Britannien’ Mr. G. W. Lamplugh gives “ Notes 
on British late-Glacial and post-Glacial deposits,’ in which he 
deals with the subject with his characteristically commendable 
caution. He concludes that ‘ without a critical discussion 
or the details. .../... it, amay-, seem. - presumptuous. to 
question the schemes of post-Glacial vicissitudes which have 
been proposed by other investigators. With regard to 
these schemes . . . the most usual attitude among 
British geologists is one of neutrality tinged with scepticism. 
In my own case the scepticism at present outweighs the 
neutrality.’ 
“ INTERGLACIAL ’ DEPOSITS. 
On the question of ‘ Interglacial’ periods Mr. Lamplugh is 
very definite. He says: ‘I have been driven to conclude, 
after many years’ field work on the drifts in various parts of 
the British Islands, that there is no clear evidence for the 
supposed separate glaciations and warm inter-Glacial epochs, 
but on the other hand there is strong evidence that the main 
ice-sheets persisted throughout the Glacial Period, and only 
their margins oscillated widely. As a corollary to this result, 
I am inclined to suppose that the post- -Glacial deposits have 
been accumulated during progressive amelioration of climate.’ 
The volume contains a very fine Introduction, or ‘ Vorwort,’ 
to the — subject, by Dr. Gunnar Andersson.
