[Material received between April 1909 and April 1910.]

The International Catalogue of Scientific Literature is in effect a
continuation of the Royal Society's Catalogue of Scientific Papers which
will, when completed, consist of an Author Catalogue and Subject
Index covering the period of 1800-1900. Twelve quarto volumes of
the Author Catalogue covering the period 1800-1883 have already been
published ; the volumes for 1884-1900 are in course of preparation.
The Subject Index will be issued separately for each of the
seventeen sciences dealt with in the International Catalogue of
Scientific Literature, and will be arranged in accordance with its
Schedules. The volumes for Pure Mathematics and Mechanics are
published. The Subject Index for Physics is in preparation.

INSTRUCTIONS.

The present volume contains (a) Schedules and Indexes in four
languages ; (b) An Author Catalogue ; (c) A Subject Catalogue.

The Schedules have been revised in accordance with the decisions
of the International Convention of 1905.

The Subject Catalogue is divided into sections, each of which is

denoted by a four-figure number between 0000 and 3670 called

a Registration number. These numbers follow one another in
numerical order.

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

To find the papers dealing with a particular subject the reader
may consult either the Schedule or the Index to the Schedule.
The numbers given in the Index are Kegistration numbers, and can be
used at once for turning to the proper page of the Subject Index. This
is done by looking at the numbers at the right-hand top corners of
the pages.

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. Tiie 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 is mainly that of 1909, but includes
those portions of the literature of 1901-1908 in regard to which the
index slips were received by the Central Bureau too late for inclusion in
the previous volumes. There are also entries dated 1910.
