ON SOUTH AFRICAN STRATA. 123 



South African Strata. — Report of the Committee, consisting of Professor 

 J. W. Gregory (Chairman), Professor A. Young (Secretary), Mr. 

 W. Anderson, Professor R. Broom, Dr. G. S. Corstorphine, 

 Dr. Walcot Gibson, Dr. F. H. Hatch, Sir T. H. Holland, 

 Mr. H. Kynaston, Mr. F. P. Mennell, Dr. Molengraaff, Mr. 

 A. J. C. Molyneux, Dr. A. W. Rogers, Professor E. H. L. 

 Schwarz, and Professor R. B. Young, appointed to investigate and 

 report on the Correlation and Age of South African Strata and on the 

 Question of a Uniform Stratigraphical Nomenclature. (Drawn up 

 by the Chairman.) 



The unity in structure and geological history of Africa south of the 

 Zambesi renders it especially desirable that the rocks of the whole 

 subcontinent should be named on a uniform system. The separation 

 of the country into six distinct political divisions — Cape Colony, the 

 Transvaal, Orangia, Natal, Rhodesia, and German South-West Africa- — ■ 

 has led to the study of its geology from various centres and to the 

 growth of overlapping systems of nomenclature which are confusing to 

 students in other countries and may give rise to future difficulty in 

 South Africa. 



The desirability of uniform names for the chief divisions of South 

 African geology was especially felt during the visit of the British 

 Association to South Africa in 1905. This feeling led to the appoint- 

 ment during the meeting at Johannesburg of a Committee to consider 

 the possibility of securing greater uniformity in practice between the 

 different States. The Committee appointed consists of the following 

 members : — - 



Representing Cape Colony. — Dr. A. W. Rogers, Professor R. 

 Broom, Professor E. H. L. Schwarz, Professor A. Young (Secretary). 



Representing the Transvaal. — Dr. G. S. Corstorphine, Mr. H. 

 Kynaston, Dr. P. H. Hatch, Professor R. B. Young. 



Representing Natal. — Mr. William Anderson. 



Representing Rhodesia. 1 — Mr. A. <T. C. Molyneux 



Sir T. H. Holland, Dr. G. A. F. Molengraaff, Dr. W. Gibson, 

 Pi'ofessor J. W. Gregory (Chairman). 



Owing to the wide distribution of the members, it has not been 

 possible to arrange a full meeting of the Committee, and most of the 

 work has been by correspondence. At meetings of members who 

 could attend in London it was resolved (1) that the object of the 

 report should be to propose a classification and nomenclature that 



1 Mr. P. P. Mennell was added at the Leicester Meeting in August 1907.
