SUBJECT INDEX 



Titles of Parts and Chapters and the page numbers at which they begin are printed in 

 heavy type. Names of ships and of genera and species are printed in italics. 



Where a single index entry (such as a geographical name) is followed by a string of page 

 numbers, the reader should consult the list of contents at the beginning of the book to 

 differentiate them by subject. 



The letters ff after a page number denote either the beginning of a chapter subdivision 

 on the subject in question or that the subject is mentioned again on one or both of the 

 next two following pages.
