Photographs of Geological Interest. — Twenty-third Report of Com- 

 mittee (Profs. E. J. Garwood, Chairman, and S. H. Reynolds, 

 Secretary ; Mr. G. Bingley, Mr. C. V. Crook, Mr. A. S. Reid, Prof. 

 W. W. Watts, and Mr. R. Welch). 



In the present report 443 photographs are listed, bringing the number in the Com- 

 mittee's collection to 7623. In the previous report (Oxford 1926) 611 photographs 

 from the Reader series were included. In the present list there are 218 photographs 

 from the Reader series ; these are mainly from the Home counties, but include 

 extensive sets from the Lizard and Llangollen areas. 



The following have kindly helped with the description of the Reader photographs 

 included in the present list : Mr. G. Barrow, Mr. E. S. Cobbold, Prof. A. Morley 

 Davies, Mr. E. H. Davison, Mr. H. Dewey, Miss M. S. Johnston, Mr. A. L. Leach, 

 Mr. R. W. Pocock, Dr. L. J. Wills, Mr. W. Wright. 



The 1926 report included a valuable series of 80 photographs illustrative of the 

 geology of the Isle of Wight taken by Mr. J. F. Jackson, and presented by Miss 

 C. Morey and her late brother, Mr. F. Morey. Miss Morey kindly gives a further 

 series of twenty-two of Mr. Jackson's Isle of Wight photographs. Mr. Jackson 

 further contributes sets from Dorset and Devon ; his photographs have a special 

 value from the fullness of detail of the accompanying descriptions. 



Important sets of photographs have been received from the following new contri- 

 butors : Mr. J. Challinor, Mr. G. Macdonald Davies, Mr. J. Ranson, Dr. W. G. 

 Shannon, and Mr. H. W. Turner. Mr. Davies' photographs, which illustrate no less 

 than fourteen counties, are a particularly well-chosen and well-printed series. Dr. 

 Shannon sends a beautiful series of enlargements illustrative of the geology of Torquay. 

 The Welsh series is much strengthened by Mr. Challinor's set from Cardigan and the 

 late Mr. T. W. Reader's from Denbigh. 



Among former contributors the Committee have to thank Mr. E. S. Cobbold, 

 Mr. G. G. Lewis and Mr. J. W. Tutcher. Mr. Lewis' varied and well-chosen series 

 includes examples from ten counties. 



Mr. T. Sheppard sends two enlargements illustrating coast erosion at Withernsea, 

 and Mr. Harold Preston one of Salcombe Cliff. 



Certain photographs by Sir A. Strahan and Mr. A. S. Reid taken many years 

 ago have been added to the collection. 



The photographs published by the Committee as prints or lantern slides are 

 obtainable from the Secretary at the following rates : —
