that from tlio Norwich brick-earth, occurred, tc/ether with a coarse, 

 granite with zircon, and a much decomposed elteoHte syenite, all 

 probably Scandinavian. 



A tine-grained basalt, identical with one from the Norwich brick- 

 earth. 



It is hoped that it may be possible to' identify the remainder of these 

 rocks and to give a fuller report on the boulder contents of the East 

 Anglian drifts in the next report.

Since the issue of the last Report in 190Jr about 600 photographs have 

 been received for the national collection. Of these 503 have been re- 

 gistered, bringing the total number in the collection to 4,817, and the 

 yearly average to 253. 



The annexed geographical scheme gives the distribution of these 

 photographs among the counties. Two English, one Welsh, seven 

 Scottish, and eleven Irish counties are still unrepresented. Somerset, 

 Kent, Yorkshire, and Bute head the list for the year, and the number 

 from the counties of Lincoln, Brecknock, Merioneth, and Fife receive 

 large proportionate increments. 



Several of the groups ai-e of exceptional interest. Professor Reynolds 

 sends some excellent studies of rock -structures, due to earth-movement, 

 from Devonshire, some very clear examples of unconformity from Glouces • 

 tershire, and a large series of views from Somerset. The same contri- 

 butor gives a beautiful group of photographs showing the weathering 

 of igneous rocks from the outposts of Cader Idris, and a number of 

 volcanic studies from Arran. 



Mr. Bingley contributes many photographs of the Triassic footprints 

 from Storeton Quarry, in Cheshire ; a considerable group, mainly illus- 

 trating glacial phenomena, from Lincolnshire ; and a series of inland 

 and coastal views in Yorkshire. He also sends several interesting views 

 taken in Derbyshire and Durham. 



Special mention should be made of a particularly important and most 

 carefully taken set of prints illustrating the ' nailbournes ' of Elham and 

 Petham in Kent. In both sets corresponding pairs of views were taken 

 from the same point, one to illustrate the bournes in the flow of the 

 winter 1903-4, and the other the dry state after cessation of this flow in 

 the following summer. These valuable sets, taken by Mr. Buckingham, 

 show how very important the registration of transitory phenomena by 

 photography can be, as in no other way is it possible to secure such a 

 satisfactory and telling record of these remarkable springs. Mankind is 

 so forgetful of them that in some cases houses, roads, and other works are 

 ccnstructed in the path of the intermittent flows. Mr. Buckingham has
