446 SECTIONAL TRANSACTIONS.— E. 



In the later stages of the prehistoric period, and at intervals during the 

 early mediaeval period, East Anglia formed a definite political unit, but with 

 the disappearance of such territorial divisions its unity became gradually 

 less apparent, and in the period between the eleventh century and the 

 outbreak of the Civil War it was distinguished from the rest of England 

 largely because of the peculiar character of its social, economic, and religious 

 history. 



During this period, however, the special features of East Anglian life 

 such as rapid economic progress, the development of trade with the con- 

 tinent, the growth of religious reform and the strength of the commercial 

 and industrial middle classes of society all served to produce a remarkable 

 unity of outlook which culminated in the unparalleled unanimity of this 

 region in its support of the Parliamentary party during the Civil War. 



Thus we may see in the Eastern Counties Association the last example of 

 a definite political unit corresponding to the natural region of East Anglia 

 and we may regard its formation as an attempt by the Parliamentary party 

 to utilise to the full the strategic importance of a region whose attitude 

 towards the religious and economic problems of the time had become a 

 foregone conclusion. 



Afternoon. 

 Mr. R. H. KiNViG. — Film : Bombay to Jamshedpur (2.0). 



Mr. J. A. Steers. — The physiography of North-west Norfolk (2.30). 



Dr. H. C. Darby. — The draining of the Fens (3.15). 



Mr. F. A. Singleton. — The MacDonnell Ranges of Central Australia 

 (with film) (5.30). 



Attention is drawn to the remarkable notches or gaps cut by the streams 

 which cross the parallel ridges of the MacDonnell Ranges, extending east 

 and west for about 250 miles in Central Australia. The usual explanation of 

 antecedent courses for the rivers, though accepted in the case of the James 

 and Water house Ranges, is questioned for the MacDonnell Ranges, for 

 which the possibility of superimposition from a cretaceous cover is tentatively 

 suggested.

Mr. W. V. Lewis. — Cirque formation in Iceland (lo.o). 



The bergschrund hypothesis of Willard Johnson was almost universally 

 welcomed as an explanation of cirque erosion. It has recently met with 

 much criticism and Johnson, himself, modified his views before his death. 

 According to this theory only the upper portions of the head-walls of 

 cirques should show plucking and shattering, the lower slopes, which were
