648 REPORT OF THE COUNCIL. 



At the beginning of August Mr. E. S. Clark volunteered, at short notice, 

 to join Sir Ernest Shackleton's Antarctic Expedition, to take the place of 

 the marine biologist to the expedition who had.been called up for military 

 service. Subsequently Mr. Nelson and Mr. Ford both joined His Majesty's 

 Forces for the period of the war, so that during the later months of the 

 year the staff was considerably reduced in strength. Dr. Orton has taken 

 charge of the fishery work during Mr. Clark's absence.
