PLATE CLX. AURORAL ARC AND CURTAIN. 



From sketches and observations made on July 5, 1902, at hr. 30 min. A.M. ; 

 looking eastward over Crater Hill and Observation Hill from Winter- 

 quarters Bay. 



The colour of almost all the auroral displays which were observed in M'Murdo 

 Sound was a pale golden-straw tint. Very occasionally there were observed also 

 traces of rose and greenish light.
