PREFACE xiii 



Antarctic to be obtained only at European libraries). We are also aware of defects 

 arising from the spasmodic working up of our material. The latter drawback has 

 arisen from the fact that it was necessary to break oft' from time to time from our 

 study in order to raise funds to defray all the cost, other than that of printing, 

 of the preparation of the memoir. By means of lectures a sum of over £800 has 

 been raised in various parts of Australia and Tasmania, and we are very grateful 

 to the audiences who so generously patronised these lectures, and so made the 

 preparation of the two volumes of this memoir possible. We must add that the 

 Royal Society have generously contributed £200 towards defraying the cost of the 

 publication, the remainder of the cost being borne by Sir Ernest Shackleton. In 

 reference to the photographs reproduced herein, whenever possible we have added the 

 name of the photographer. All were taken by members of the expedition, but in 

 many cases it has now been found impossible to trace the name of the photograjjher. 

 The rough sketches of the coast-line from Cape Bernacchi to Mount Nansen, and 

 inland towards the South Magnetic Pole, were made by one of us (T. W. E. David), 

 and we are much indebted to Mr. K. Craigie for i-edravving these for repi'oduction. 

 He has also redrawn in black and white several of our photographs, which otherwise 

 would have been too inferior for printing. Our acknowledgments are also due to 

 Ml'. H. E. C. Robinson for the great care with which he has prepared our maps and 

 sections. We are indebted above all to Sir Ernest Shackleton for the constant 

 sympathetic encouragement which he gave us throughout in our work, and the 

 invaluable collection of fossils brought back from the Beardmore Glacier by himself, 

 Wild, Adams, and Marshall, under conditions of extreme risk and hardship. We 

 have also to thank our colleague James Muriay for useful notes about thaw and 

 ocean currents in the neighbourhood of Cape Royds. Valuable assistance was also 

 rendered us by our late colleague Mr. Bertram Armytage, as well as by other 

 members of the expedition. We are particularly indebted to Mr. C Hedley, of the 

 Australian Museum, for his contributions on the mollusca of the raised beaches and 

 upthi'ust marine muds ; to Mr, Frederick Chapman, of the National Museum, 

 Melbourne, for his account ot the Foraminifera and Ostracoda derived from these 

 marine muds ; as well as to Mr. T. Griffith Taylor for his notes on the Archceocyathinre 

 in the Cambrian limestones of the Beardmore Glacier. Professor Skeats, of the 

 University of Melbourne, has contributed important notes on the Cambrian lime- 

 stones, a subject on which, of course, few can speak with such authority. What, 

 perhaps, has been a no less laborious, and in some cases certainly a still more tedious 

 and difficult, task has been the elaboration of our large petrological collection. This 

 work has been done by Dr. Jensen, Professor Woolnough, Dr. Allan Thomson, W. N. 

 Benson, A. B. Walkom, and Dr. D. Mawson, to all of whom we beg to express 

 our hearty gratitude, while to Mawson we owe the map of the coast from Cape 

 Bernacchi to Mount Nansen, compiled from his theodolite survey. Mr. Arthur W. 

 Allan has been unremitting in his kind attention to the business side of our work;
