 tunity of acknowledging the friendly assistance which has been extended 

 to me by all the Naval Officers of the Expedition whenever information was 

 desired in connection with the Editorial Work. A similar acknowledgment 

 must be extended to Captain Sir Frederick J. Evans, K.C.B., till lately the 

 Hydrographer, and the Officers of the Hydrographic Department of the

 Herbarium, Kew, and to Professor Archibald Geikie, the Director-General of 

 the Geological Survey, as also to T. Digby Pigott, Esq., the Controller, and 

 Gentlemen in the various departments of Her Majesty's Stationery Office. 



To Dr. A. Giinther and the Naturalists in the British Museum I 

 return my thanks for the trouble they have at all times taken in deter- 

 mining or assisting in the determination of specimens, and in furnishing 

 me with short Reports on the Incidental Terrestrial Collections from 

 the Oceanic Islands. To the Rev. O. P. Cambridge and many other 

 Naturalists and Scientific Men at home and abroad I am also indebted for 

 like information and services. 



In the Editorial Work connected with the passing of the Official Reports 

 through the press, I have for more than two years had the able assistance 

 of Mr. W. E. Hoyle, M.A., M.R.C.S., and for a shorter period of Mr. Frank E. 

 Beddard, M.A. In the general scientific and other work of this Office valuable 

 assistance has also been rendered by Mr. James Chumley, Mr. Frederick 

 Pearcey, and Mr. James Monteith. In various ways while engaged in the 

 preparation of the Narrative of the Cruise I have been assisted by Mr. Hugh 

 Robert Mill, B.Sc, Mr. J. Rattray, M.A., B.Sc, Mr. J. T. Cunningham, B.A., 

 and Mr. H. Roscoe Dumville, B.A. 



To the Artists, Engravers, Lithographers, and Printers who have been 

 engaged in the work my thanks are also due.
