which, since the days of Sutherland, has been correlated with the Table 

 Mountain Sandstone of Cape Colony, this formation bears the closest 

 resemblance to the Waterberg Sandstone of the Transvaal, and thus 

 lends further support to the correlation of the latter with the Cape 

 formation. If this view be correct, the Matsap beds of Griqualand 

 West, which have been shown by Sogers 1 to be older than the Table 

 Mountain Sandstone of the Cape, cannot be correlated with the Water- 

 berg Sandstone of the Transvaal. 



Photographs of Geological Interest. — Seventeenth Report of the Coni' 

 mittee, consisting of Professor J. Geikie {Chairman), Professorj 

 W. W. Watts and S. H. Reynolds {Secretaries), Dr. Tempest 

 Anderson, Mr. G. Bingley, Dr. T. G. Bonney, Mr. C. V. Crook 

 Professor E. J. Garwood, Messrs. W. Gray, R. Kidston, and 

 A. S. Reid, Dr. J. J. H. Teall, and Messrs. R. Welch, W. 

 Whitaker, and H. B. Woodward. {Draivn up by the Secretaries.) 



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

 in 1908 there have been received 410 photographs for the national 

 collection. The total number in the collection is now 5,227, and the 

 yearly average amounts to about 250. 



These photographs have been received, acknowledged, catalogued, 

 mounted, and stored at a cost to the Association of 4"6i. per print, 

 or, adding the collection of about 453 duplicates, a cost of 4"3tZ. per 

 photograph. 



The Geological Survey continues to provide accommodation for the 

 storage of the collection and provides facilities for inspection by the 

 public and work upon the collection by the Secretaries. 



The annexed geographical scheme shows the distribution of the 

 new accessions among the counties. Dumbartonshire figures in the 

 scheme for the first time, and notable additions are recorded in the 

 counties of Dorset, Gloucester, Somerset, Yorkshire, Pembroke, 

 Inverness, Galway, Mayo, and the Isle of Man. 



The principal contributors this year are Mr. Bingley and Professor 

 Reynolds. The former continues his survey of the Yorkshire coast, 

 and sends also series from Richmond, Leeds, and Pickering. He con- 

 tributes, moreover, photographs from the Isle of Man and the Welsh 

 borderland. Professor Eeynolds gives a set of serial sections taken on 

 both sides of the classical Avon Gorge, and series from Skye and the 

 Dorset coast. In addition, he sends photographs from Hereford, 

 Somerset, Yorkshire, a considerable Welsh series, chiefly Carboniferous 

 and volcanic, and several sets from regions in Scotland and Ireland. 



An interesting and beautiful set of Carboniferous and Devonian 

 volcanic photographs comes from Mr. R. Vowell Sherring, and 

 examples taken during excursions of the Geologists' Association by
