 is liable to fog the plates. If plates do fog,

 died on March 31st, at the age of 84, had had a 

 long and varied career. He joined the Navy in 

 1829, served in the Antarctic expedition of 

 1839 under Sir James Boss, and only missed 

 serving as lieutenant to his old friend Sir John 

 Franklin in his last fatal Arctic expedition owing 

 to his arrival in England too late. He had al- 

 ready served five years under that ofiicer in 

 Tasmania as naval architect and surveyor. 

 From 1846 to 1866 (when he retired) he was em- 

 ployed on the marine survey of the Canadian 

 Atlantic coast. From 1869 to 1889 he served 

 in the marine department of Canada, the pro- 

 tection of the fisheries, as examiner for masters' 

 and mates' certificates, and a-s general nautical 

 adviser, and was well known to all who served 

 on the North American station for his geniality 

 and hospitality. 



The London Times, also, states that Mr. 

 William Cross, the well-known naturalist and 

 dealer in wild animals, has died at Liver-
