112 REPORTS ON THE STATE OF SCIENCE. — 1919. 



P' Photographs of considerable value have been received through Mr. 

 Whitaker from the executors of the late Mr. H. B. Woodward. They 

 include photographs of Gotham Marble, and of a perhaps analogous rock 

 from the Purbeck, the latter being from negatives by Professor Watts. 

 They further include views from Norfolk, Herts (Sir J. J. H. Teall), and 

 Kent (H. C. McNeill), and three from Skye by Messrs. G. P. Abraham, 

 Valentine and Sons, Ltd., and G. W. Wilson. The Committee are much 

 indebted to Dr. Alfred Harker for the full descriptions, with illustrative 

 sketches, which he kindly provided for the Skye views. 



Mr. W. Whitaker sends a set of picture postcards, illustrating the geology 

 of the neighbourhood of Brighton. Many excellent postcards of geological 

 subjects are obtainable, and it is to be hoped that other contributors will 

 follow Mr. Whitaker's example. 



Photographs bv Mr. J. G. Hamling, Miss B. Hendriks, Miss M. S. 

 Johnston, Mr. J. H. Pledge, Miss H. D. Sharpe, Sir A. Strahan, Mr. G. W. 

 Young and Mr. W. P. Young have also been received. To all contributors 

 the Committee tender sincere thanks. 



The Committee hope that before the issue of the next Report the new 

 series of geological photographs which has so long been promised will be 

 published. Reissue of the former series is also under consideration. 



The Committee recommend that they be reappointed.
