BRYANT, B.A. INTEENATIO^^AL CATALOGUE OF SCIENTIFIC LITEIIATUEE FiEST Annual Issue, ASTRONOMY PUBLISHED FOU THE INTERNATIONAL COUNCIL ROYAL SOCIETY OF LONDON. LONDON : Haerisox and .Sons. 45, St. Maktins Lank. VOL. V : 1902 (AUGUST). /?c?c^< PREFACE. Tbe Internatioxal Catalogue of Sciextikic Literature, com- nieucing- with tbe literature of the year 1901, is an outgTOwth of the Catalogue of Scientific Papers relating- to the scientific literature of tlie nineteenth century, published by the Royal Society of London. The suggestion to catalogue scientific papers may be traced back to Prof. Henry, of Washing-ton, U.S.A., who broug-ht the subject under the notice of the British Association for the Advancement of Science at its meeting- in Glasg'ow, in 1855. The history of the incep- tion of the enterprise is recorded in the first volume of the Catalogue of Scientific Papers issued by the Iioyal Sociely in 1867. Twelve large quarto volumes have been printed in which the titles of papers published during the period 1800-1883 are aiTanged under authors' names. A subject index, which will serve as a key to these volumes and also form an independent record, is in an advanced state of preparation. A catalog-ue of the scientific papers published during the period 1884-1900 is now being- prepared by the Koyal Society of London. The possibility of preparing a complete index of currert scientific literature by international co-operation was first taken into considera- tion by the Royal Society about the year 1893. It had long been apparent that the work was beyond the resources of the Society, or indeed of any single body. Moreover, it was felt that an authors' catalogue could not supply the required information, and that it was essential that scientific workers should be kept fully and quickly informed of all new discoveries by means of complete subject indexes, luternational co-operation appeared to be the only means of carrying out such a work with the necessary completeness and rapidity. The Society therefore sought the opinion of a very large number of representative bodies and individuals abroad; and, as the replies were almost uniformly in favour of the work being uudertaUen 1>3' int< ruational co-operation, ste|)S were taken to sunnnon an International Conference of Delegates appointed by various Governments. The Conference took place in Ltrndon on July 14-17. 189(3, and was attended by delegates from Canada, Cape Colony, Denmark France, Germany, Greece, Uungary, India, Italy. Japan, i\Iexico, Natal, the Netherlands, New South Wales, New Zealand, Norway, Queensland, Sweden, Switzerland, the Uniteil Kingdom, and the United States. It was unanimously resolved that it was desirable to compile and publish, by means of an international organisation, a complete Catalogue of Scientific Literature, arranged according both to subject matter and to authors' names, in which regard should be had, in the first instance, to the requirements of scientific investigators, so that these might find out, with a minimum of trouble, what had been published on any particular subject of enquiry. It was agreed that the material should, as far as possible, be collected in the various countries by local organisations established for the purpose, and that the final editing and publication of the Catalogue should be entrusted to a Central International Bureau, acting under the direction of an International Council. It was agreed to establish the Central Bureau in London. Although the question of the method to be adopted in classifying the subject matter of the several sciences was discussed at great length, no decision other than one adverse to the Dewey system was arrived at. The Royal Society was requested to appoint a Com- mittee to take this and many other questions of detail left undecided by the Conference, into consideration. As the result of the arduous labours of this Committee, complete schedules were prepared for each of the sciences to be catalogued, and a financial statement was also prepared showing the estimated cost of the Catalogue. The report of ihe Committee was considered at a second Conference, held in London on October 11-13, 1898, which was attended by accredited representatives from Austria, Belgium, Cape Colony, France, Germany, Hungary, India, Japan, Mexico, Natal, the Nether- lauds. New Zealand. Norway, Queensland, Sweden, Switzerland, the United Kingdom, and the United States. At this meeting the conclusions arrived at by the first Conference were generally confirmed, and much progress was made in deciding the principles to be adopted in preparing the Catalogue. Full schedules for the several sciences, which had been prepared by the Connnittee of the Koyal Society, were laid before tlie delegates. Ultimately, after prolonged discussion, it was decided to adopt an arbitrary combiued system of letters, numbers, and other symbols, adapted in the case of each branch of science to its particular needs. A Provisional International Committee was appointed to settle authoritatively the details of the schedules. The financial position was fully discussed, but no definite conclusions could be arrived at. The delegates attending the meeting were requested to obtain further information on the subject in their respec- tive countries, and to report to the Provisional International Committee. The Provisional International Committee met in London on August 1-5, 1899. The Committee had arranged for the co-option of an Italian and a Russian member, and M. Th. Koppen attended as the representative of Russia. The reports received from various countries were considered. Schedules for the seventeen branches of science to be included in the Catalogue were approved for adoption. The financial position was again very fully considered, especially in relation to the establishment of the Central Bureau ; and it was finally resolved to recommend that the Roya] Society be requested to organise tlie Central Bureau, and to do all necessary work, so that the preparation of the Catalogue might be commenced in 19UJ. Mainly in consequence of representatious made by the German Govermneiit. in order to reduce the cost of the enterprise the Pro- visional International Committee agreed to recommtnd that the Catalogue should at the outset be of a more restricted character than was contemplated by either the first or the second Conference, that is to say, that the issue of a card catalogue should be postponed, and that the number of subject entries should be kept within narrow limits. A third International Conference was held in London on June 12 and 13, 1900. This was attended by accredited representatives from Austria, Cape Colony, France, Germany, Greece, Hungary, India, Italy, Japan, Mexico, Natal, New Zealand, Norway, Queensland, Switzerland, and the United Kingdom. The report of the Provisional Inter- national Committee appointed at the second Conference was considered, and also a detailed scheme for the publication of the Catalogue whicli had been prepared, at the request of the Committee, by the Royal Society. The statements made by the delegates of various countries as to the extent to which they were authorised to promise contributions towards the expenses of the Catalogue being satisfactory, it was resolved to take further steps towards the publication of the Catalogue ; and for this purpose, pending the appointment of an International Council, the ('onfei-euce again appointed a Provisional International Committee. This Committee met at the conclusion of the Conference, and after- wards continued its deliberations through the agency of the Royal Society. All difficulties were finally removed by the Royal Society undertaking to act as the publishers of the Catalogue on behalf of the International Council, therebj'^ giving the necessary legal status to the undertaking, and also to advance the capital required to start the enterprise on the understanding that this should be repaid during the ensuing five years. The supreme control over the Catalogue is vested in an International Convention. Such a Convention is to be held in London in 1905, in 1910, and every tenth jear afterwards, to reconsider, and, if necessary, to revise the regulations for carrying out the work of the Catalogue ; but the approved Schedules are not to be altered during the first period of five years. In the interval iietween two successive meetings of the Convention the administration of the Caialogue is vested in an International Council, the members of which are to be appointed by the Regional Bureaus. The first meeting of the International Council was held in London on December 12, 1900, when it was decided to commence the preparation of the Catalogue from January 1, 1901, At this meeting an Executive Committee was ai)pointed, consisting of the delegates of the Royal Society and representatives o( the four largest subscribers — the United States of America, ( Jermany, France, and Italy. The materials (nit of which the Catalogue is formed are to be furnished by Regional Bureaus. A 3 Regional Bureaus have already been established in Belgium, Canada, Cape Colony, Denmark, Egypt, France, Great Britain and Ireland, Germany, Greece, Holland, Hungary, Italy, India and Ceylon, Japan, Mexico, New Zealand, New South \\"ales, Norway', Portugal, Poland, Queensland, Russia, South Australia, Sweden, Switzerland, the United States of America, Victoria, Western AustraUa, Finland. The branches of Science to be included in the Catalogue are the seventeen following : — A — Mathematics B — Mechanics C — Physics D — Chemistry E — Astronomy F — Meteorology (including Terrestial Magnetism) G — Mineralogy (including Petrology and Crystallography) H — Geology J — Geography (Mathematical and Physical) K — Palfeontology L — General Biology M — Botany N — Zoology 0 — Human Anatomy P — Physical Anthropology Q — Physiology (including experimental Psychology, Pharmacology and experimental Pathology) R — Bacteriology Each com2:)lete annual issue of the Catalogue will thus consist of seventeen volumes. The price at which this set will be sold to the public is £18. Individual volumes will be sold at pi'ices varying with their size from about ten to thirty-five shillings. A Schedule of Classification and an Index thereto will be pre- fixed to each volume in English, French, German, and Italian. This will not only enable the scientific worker to study the system of classification in the language with which be is most familiar, but also in cases of doubt — e.g. as to the meaning of a word — will enable him to refer to the corresponding entry in another language. Should there be a marked discrepancy among the schedules on any point the English schedule is to be taken as guide, the schedules printed in that language being those which were approved by the International Council. The various headings and sub-headings throughout the Subject Index are given in English. Translations of the main headings can be found on reference to the schedules in the other languages by means of the registration numbers that are attached to them. The entries in the Subject Indexes are in the language of the original paper when that is one of the following five languages : Latii], English, French, Gei'man, and Italian. These are the only languages used in the Subject Index, but in case of translation the name of the language of the original is inserted within round brackets. In the Authors' Catalogue each title is given in the original language. When, however, that language is not one of the five above mentioned, a translation into one of these five lang-uages is added. In such cases the actual title is printed first, and is followed by the translation within square brackets. It was provided by the orig-inal scherae that the Catalog'ue should comprise all original contributions to the branches of science which come within its scope, whether these had been published in periodicals, or in the journals of societies, or as independent pamphlets, memoirs, or books. In order that a scientific investigator might be in a position to ascertain by means of the Catalogue what has from time to time been published concerning each particular subject of inquiry, it was held to be of great importance that not only the titles of papei'S but their subject matter also should be indexed. As stated above, however, financial considerations have led to the number of subject-entries being at present limited in number. But the expense of making subject-entries would be very greatly reduced if all periodicals adopted a practice already carried out by some journals, namely, that of indexing each paper at the time of its publication. Indeed, were this carefully done, the Bureaus preparing the Catalogue would no longer have to study the contents of papers in order to prepare the subject-entries, and the saving thereby effected would make it possible to enlarge the scope of the Catalogue, until it include all original scientific communications. Seeing how necessary such a complete subject catalogue is for the progress of science, it is hoped that all editors and authors will co-operate in so preparing subject-indexes for all papers at the time of their publication.

The present volume consists of three parts : — (a) Schedules and Indexes in four languages (b) An Authors' Catalogue. (c) A Subject Catalogue. The Subject Catalogue is divided into sections, each of which is denoted by a four-figure number between OCOO and 9999. These numbers follow one another in numerical order, but all the 9999 numbers are not used, for it is intended to fill up the gaps by interpola- tion of such additional sections as may be required for additions to the system of classification in futiu'e 3'ears, To enable the reader to find these numbers quickly, the first or last number on the page is repeated at the head of the page. In looking up a subject, these numbers, which are called Registration numbers, should be used instead of the ordinary pagination. These Registration numbers serve to divide up the subject into sections, each of which deals with related matter. It has been sought, as far as possible, to separate, for instance, spherical and dynamical astronomy methods, calculations and observations ; and also to classify under Sun, Moon, Planets, Comers, Double Stars, &c,, &c,, and in many cases to have further sub-divisions for observations of a different character of the same object, e.g., observations of position will, as a rule, be found separated from spectroscopic or other physical observations, drawings, &c. To save space, the separate planetar^^ headings are only given under jMercur3% the third figure in the number being the same for similar observations of any other planet; e.g., observations of position of i^appho will be found under o9lU; markings on Mars 5«40, &c.. &c. All papers relating- to a particular Comet should be found in the Comet Section 6600, under tlie designation of the Comet, such being- in order of date and number, All papers of the same character relating to a particular minor planet should similarly be found in the corres- ponding- section {e.g., 5960 for brightness) under the permanent number (or provisional letter where no number is yet assigned) ; each section being arranged in numerical order. It has not been considered advisable to attempt this analysis of papers in the case of stars (variable or double). If the reader remember the name of the Author of a paper on a given subject, he will probably fiud it convenieut to refer to the Authors' Catalogue rather than to the Subject Catalogue. In the Authors' Catalogue the four-figure 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.
