The work of securing the assistance of these specialists and of distributing the 

 collections has been performed by Mr. Jeffrey Bell, of the Zoological Department, who 

 has also acted as sub-editor of the Zoological and Botanical portions of the reports. 

 The Keeper of Minerals, Mr. Fletcher, has superintended the reports in the subjects 

 belonging to his department. 



The Director desires to acknowledge the ability and energy which have been 

 brought to bear on the preparation of the Zoological reports by Mr. Jeflrey Bell. 

 Owing to his care, the reports have been got ready by the various contributors and 

 published within a reasonable time after the return of the ' Discovery ' from the 

 Antarctic Regions. Neither trouble nor expense has been spared in order to 

 render the illustration and presentation of the Natural History of the Expedition 

 worthy of the generous efforts both of Captain Scott and his fellow-explorers and 

 of those who provided the funds for that enterprise.
