Vlll PREFACE. 



White, Assistant Engineer of H.M.S. ' Alert,' or from 

 sketches taken on the spot by Dr. Edward Moss, M.D., 

 Surgeon of H.M.S. 'Alert,' Lieutenant G. Le C. 

 Egerton, and Mr. Mitchell. 



The Natural History collections made by the two 

 naturalists who were attached to the Expedition were, 

 on the recommendation of the President and Council of 

 the Eoyal Society, submitted to specialists, who have 

 most kindly and generously drawn up full reports on 

 the various groups. Many of these papers have already 

 been published in the proceedings of various learned 

 societies. In the Appendices to this work, my friend 

 Captain Feilden, the naturalist attached to the ' Alert,' 

 in addition to supplying original papers, has arranged 

 in an abridged form these valuable contributions to 

 Natural History. 



Throughout the narrative the compass bearings 

 refer to the true meridian ; and the temperature 

 observations are expressed in degrees of Fahrenheit.
