lytical practice for a number of years. The work 

 as a whole was reviewed in these columns on the 

 occasion of the previous issue, and its general 

 plan remains unchanged, though the matter has 

 been re-written and many additions made. These 

 include, in the volume under notice, a number of 

 hitherto unpublished results obtained in the 

 author's laboratory, and also data respecting 

 certain oils such as those from perilla seed and 

 rubber seed which, though little known in this 

 country at present, may perhaps prove of com- 

 mercial importance in the future. There are also 

 some revisions of the older values for the physical 

 and chemical "constants " in cases where the adop- 

 tion of improved processes for the preparation of 



makes them very convenient for use as guide 

 books, a purpose they will be found to serve 

 admirably, without in any way interfering with 

 their popularity as interesting supplements to geo- 

 graphy lessons in schools. Both authors may be 

 congratulated upon maintaining the high stand- 

 ard set in previous volumes.

 led to the tragic deaths of two of his companions, 

 promises to be very great. Before this expedi- 

 tion, as the maps show, little was certainly known 

 about the Antarctic continent for quite 70° of 

 longitude, from some distance west of Cape 

 Adare to the winter quarters of the Gauss in 

 1902-3. The geography of this, as the maps 

 show, has now been ascertained by adventurous 

 and laborious sledge journeys from the two bases 

 occupied by Mawson 's expedition, and the follow- 

 ing are its main results.
