relatively stable sides, and the anticlinal structure was due to 

 a slight reversal of the earlier direction of movement. Similar 

 conceptions were extended to the Jurassic rocks of the Midlands an/d 

 of Yorkshire ; in both cases the recumbent wedge was found to be in 

 evidence, and such structures can probably be traced in Triassic, 

 Carboniferous, and even older rocks. It was also pointed out that 

 where such formations lie above sea-level their outcrops represent 

 areas of maximum development and coincide with the deepest parts 

 of the old troughs. These considerations may be of wide application 

 and have a practical bearing.

The Report of the Council of the Geological Society of London, 

 presented at the Annual General Meeting on February 21, must be 

 regarded as highly satisfactory considering all the circumstances of 

 the time, since it shows that the Society has been able to keep most 

 of its activities unimpaired. The number of Fellows shows, as might 

 be expected, a slight decrease, and there are a good many vacancies 

 in the list of Foreign Members and Correspondents. The financial 

 position is satisfactory, in spite of the increased cost of nearly 

 everything, and more especially of paper and printing. The pro- 

 duction of volume lxxiii of the Quarterly Journal cost over £860 

 exclusive of postage. The generous action of the Council in 

 remitting the annual contributions of those Fellows on active service 

 has led to a diminution of receipts for some years, but that is now 

 presumably a thing of the past. An increase of income may be 

 expected in the future from the admission of women as Fellows, 

 although this is not likely to be very great, at any rate for some 

 time to come. It is well known that the Society's library has been 

 found of the utmost value during the War to the Admiralty, the 

 War Office, and many other Government departments, since it 

 contains publications, and especially maps, not to be found elsewhere 

 in this country. • It is gratifying to observe that a small sum has 

 been set aside from the Prestwich Trust Fund for the purchase of 

 books' on economic geology, in which the library is still somewhat 

 deficient. It is certain that the demand for economic literature will 

 increase greatly in the immediate future, and this is a step in the 

 right direction.

The Cambridge University Reporter for February 18 last announces 

 the subject for the Sedgwick Prize Essay for 1922 as follows: 

 "The Petrology of the Arenaceous Sediments of Lower Cretaceous 

 Age in England, with special reference to the Source of the 

 Material." The prize, which is triennial and of the value of about 

 £80, was not awarded in 1915 or 1918, as is natural under the 

 circumstances, but even in normal times it has happened that no 

 essays have been sent in. This is possibly owing to one of the 

 conditions : that the prize shall be open to all graduates of the 

 University who have resided in Cambridge for sixty days during 

 the twelve months preceding the date at whicli the essay must be 

 sent in. This greatly limits the number of possible candidates, since
