Index. The reader will find there is no index.
The contents list, however, supplies in detail the
page numbers of the major heads of subject matter,
so doing duty which would otherwise be served by
an index. Thus reference can be made via the contents
list to particular places and subjects. Likewise,
references to flora and fauna, in general or at
particular localities, can be obtained by use of the
relevant tables, as well as via the contents list.
