GEOLOGICAL OBSERVATIONS IN SOUTH GEORGIA. 813 



Concluding Observations. 



In conclusion, the writer would like to put on record the generosity of the Messrs 

 Chr. Salvesen & Co., the well-known shipowners of Leith, and of Mr Theo. E. 

 Salvesen, the member of the firm who directs their extensive whaling industry in 

 South Georgia, the South Shetlands, and the Falkland Islands. They are the lessees 

 of the minerals and mining rights on all the islands owned by His Majesty King 

 George V. in the South Atlantic, outside the Falkland Islands. They have not, 

 however, confined themselves to their own special interests, but have assisted and 

 encouraged the elucidation of the interesting geological problems presented in that 

 outlying portion of the empire. They have also presented the rock and fossil 

 specimens brought home from South Georgia to the Geological Department, 

 Glasgow University, and the Scottish Oceanographical Laboratory, Edinburgh. 



The writer is much indebted for help in the examination and description of the 

 material collected to Professor J. W. Gregory, D.Sc, F.R.S., and his assistants in 

 the Geological Department, Glasgow University ; Miss M. Macphee ; G. W. 

 Tyrrell, Assoc. Eoy. Col. So., F.G.S. ; and W. R. Smellie, M.A., B.Sc. 



Professor Gregory's discussion of the physiography of South Georgia forms an 

 Appendix to the present paper. His discussion of the geological relations and of 

 the fossils, and Mr Tyrrell's description of the petrology, form separate papers 

 following immediately on this.
