INSTRUCTIONS.

The pre«eut volimie cousists of tliree parts : —

(a) Schedules aud Indexes \n fouf lang'ua^es.

(b) An Author Catalogue.

(c) A Subject Catalogue.

The Subject Catalogue is divided iuto sections, each of which is
denoted by a four-figure number between 0000 aud 9999 called a
Registration numbei'. These numbers follow one another in numerical
order, but all the 9999 numbers are not used.

To enable the reader to find these numbers quickly, the first and last
uuml)er on the page is repeated at the right and left corner at the
head of each page in the Subject Index. This also has the advantage
of giving to the pages of the Subject Catalogue a mark by which they
can be distinguished at a glance fi'om the pages of the Author
Catalogue.

In each section the final arrangement of papers is in the
alphabetical order of authors' names.

In order to find the papers dealing with a particular subject the
reader may either consult the Schedule or the Index to the Schedule.
The nunibeis given in the index are Registration numbers, and can be
used at once for turning to the proper page of the Subject Index. This
is dune by looking at the numl)ers at the outer top corners of the
pages.

If the reader remember the name of the author of a paper on a
given subject, he will probably find it convenient to refer to the
Author Catalogue rather than to the Subject Catalogue.

In the Author Catalogue the numbers placed within square brackets
at the end of each entry are Registration numbers, and serve to
indicate the scope of each paper indexed. The meaning of these
numbers will at once be found by reference to the Schedule.

In case the abbreviated titles of Journals are not understood, a key
to these is provided at the end of the volume.

The literature indexed in this volume is mainly that of 1904, but
includes such portions of the literature of 1901-1903 as may have
been found to have been omitted from previous volumes.
