place-names, and in so many other ways — not only in the production of the 

 book, but also in the original arrangement and fitting-out of the expedition —that 

 it is impossible to over-estimate our obligation to his kindness. 



Owing to the circumstances under which a great part of the manuscript 

 was produced, it stood in need of considerable revision and compilation, and in 

 the absence of both authors from England, Major C. H. Chepniell, late R.A., 

 kindly undertook these duties, and has carried out a difficult task with 

 painstaking skill. Expert assistance was obtained where special knowledge 

 was required; and our best thanks are due to Mr. R. I. Pocock, F.R.S., 

 Professor J. Logan Lobley, F.G.S., F R.G.S., and Mr. R. Corless, M.A., 

 F.R.Met.Soc, . for consenting to revise our proofs dealing with Natural 

 History, Geology, and Meteorology respectively.
