The Committee have to report that since the issue of the last Report in 

 1910 they have received 429 photographs for the national collection. 

 The total number in the collection is now 5,656, and the yearly average 

 amounts to about 210. 



Since the issue of the last Report the Committee have suffered the 

 loss of Professor James Geikie, their Chairman for twenty-six years. 

 They have also lost Dr. Tempest Anderson and Mr. H. B. Woodward, 

 both of whom took great interest in the work of the Committee and 

 made contributions to the collection. 



The geographical scheme appended shows the distribution of new 

 accessions among the counties. Kincardineshire figures in the list for 

 the first time, and considerable additions have been made from Corn- 

 wall, Durham, Somerset, Surrey, and Inverness ; while Yorkshire, with 

 an addition of 127, has now over a thousand prints in the collection. 



Mr. Bingley adds still further to his photographic survey of the 

 Yorkshire coast, as well as sending sets from the Yorkshire Dales, from 

 Settle, and from Leeds. He also contributes a carefully selected set 

 from the Magnesian Limestone of the Durham coast. To him we owe 

 prints from Cumberland, "Westmorland, Lancashire, and the Isle of 

 Man. 



Pit>fessor Reynolds has illustrated the coasts of Cornwall and 

 Devon, with the Carboniferous Limestone districts of Gloucester and 

 Somerset. The igneous and ancient rocks of many parts of Scotland 

 are also illustrated by him, particularly in Argyll, Forfar, Inverness, 

 and Sutherland. He also contributes prints from Galway and Mayo. 



Mr. A. S. Reid records the growth of deltas in certain Scottish 

 Lochs; his photographs should be compared with Nos. 1867 and 1868. 



Mr. R. Welch contributes very interesting series of prints taken 

 with his usual skill and finish, from Derbyshire and from several Irish 

 counties, including Clare and Limerick. 



The late Mr. Russell Gwinnell sent numerous photographs taken in 

 Skye and on the mainland ; and Mr. Zealley took photogi'aphs to illus- 

 trate his work in the North of Ireland. 



Photographs sent by Mr. Wickham King record his discovery of 

 Downtonian rocks in the South Staffordshire Coalfield. Mr. L. 

 Richardson sends prints in illustration of his Rhpetic work. Colonel 

 Haywood has photographed the coast scenery of the Isle of Man, and 

 Mr. Cornewall- Walker presents, through Mr. Whitaker, a record of the 

 excavations for a reservoir in Tunbridge Wells Sand, near Lingfield.
