SCIENTIFIC BESULTS OF TSE TEEBA 

 NOVA EXPEDITION 



The British Museum has undertaken the 

 publication of the Natural History results of 

 the British Antarctic Expedition of 1910, 

 better knovsm as the Terra Nova Expedition. 

 These results will be issued in parts as fast 

 as they are prepared. The first part to be 

 printed is a description of the fossil plants by 

 Professor A. C. Seward of Cambridge.^ 



An especial interest attaches to the small 

 collection of geological specimens that were 

 retrieved after the tragic death of Captain 

 Scott and his heroic associates, and the pres- 

 ent publication bears ample testimony to the 

 fact that their efforts have not only furnished 

 the world with a lasting monument to British 

 pluck and manhood but have also yielded facts 

 of the greatest scientific interest. 



Although determinable fossil plants are few in 

 number traces were seen, as well as numerous 

 carbonaceous laminae and small seams of coal, 

 at a number of widely separated localities, par- 

 ticularly in what is called the Beacon sand- 

 stone, which at latitude 85° S. is 1,500 feet 

 thick. This comprises an upper 500 feet of 

 sandstone resting on 300 feet of interbedded 

 sandstone and shale with several seams of coal, 

 underlain by TOO feet of similar sandstone 

 conglomeratic at the base. The character of 

 the grains in the sandstone suggests wind 

 action, and sun cracks and ripple marks have 

 also been observed. This extensive formation 

 has been traced from Mt. Nansen as far south 

 as latitude 85°, a distance of over YOO miles. 



The most significant plants are those repre- 

 senting the genus Olossopteris found at Mount 

 Buckley or Buckley Island which is situated 

 just west of the Beardmore Glacier in latitude 

 85°. These are partly referred to the wide- 

 spread Glossopteris indica Schimper and in 

 part described as a new variety of that species. 

 There are also represented objects identified 

 as those of Vertehraria and representing the 

 axial organs of Glossopteris, and others doubt-
