Mr. Priestley, now on the faculty of Cambridge University, 

 was a member of the scientific staff of the British Antarctic Expedi- 

 tions under Shackleton (i 907-1 909) and Scott (1910-1913), serving 

 as geologist. As a result of the investigations made on these expedi- 

 tions he has published, in collaboration with C. S. Wright, the re- 

 port on "Glaciology " in the scientific results of the British Antarctic 

 Expedition of 1910-1913, London, 1922, now the most authorita- 

 tive treatment in English of the subjects with which it deals. He 

 has also published a general narrative, "Antarctic Adventure: 

 Scott's Northern Party," London, 1914; "Physiography of the 

 Robertson Bay and Terra Nova Bay Regions" (British Antarctic 

 Expedition, 1910-1913, Reports, London, 1923); and a "Syllabus 

 of a Course of Lectures on the History and Science of Polar Explora- 

 tion, " Cambridge University. With Sir T. W. Edgeworth David he 

 prepared the report on "Glaciology, Physiography, Stratigraphy, 

 and Tectonic Geology of South Victoria Land" (British Antarctic 

 Expedition, 1907-1909: Reports of the Scientific Investigations: 

 Geology, Vol. i, London, 1914) in which the chapters " Physiographic 

 Introduction" and "Notes on the General Geological Relations of 

 Antarctica to Other Parts of the World" are of special geographical 

 interest. 



Dr. TiLLEY, demonstrator in petrology at Cambridge University, 

 formerly held a similar position in geology and mineralogy at the 

 University of Sydney. He has published a number of papers on 

 the petrology and geology of South Australia and has contributed 

 "The Metamorphic Limestones of Commonwealth Bay, Adelie 

 Land" to the scientific reports of the Australasian Antarctic Ex- 

 pedition, 1911-14 (Series A, Vol. 3: Geology, Part II, Sydney, 1923.)
