The system of transliteration adopted for the names of Knssian authors is/ 

 with some slight modifications, that approved by the late Director of the Natural 

 History Museum, Mr F. Ldwinson-Lessing, of the University, St Petersburg, and 

 others, and set forth in Nature, Feb. 27, 1890, vol. xli. p. 397. 



Numerous cross-references have been given, so that it is hoped that no 

 difficulty will arise in discovering the place where the works of any Russian 

 author occur in the following pages. 



Great pains have been taken to secure, so far as possible, typographical 

 accuracy, and various errors which have been discovered in former volumes have 

 been corrected. As with former volumes the thanks of the President and 

 Council are due to several members of the Catalogue Committee who have 

 undertaken the revision of the proofs with especial reference to those branches 

 of science with which they were immediately concerned. 



The authorities of the British Museum, the Patent Office, the Museum of 

 Practical Geology, the Royal College of Surgeons of England, and various learned 

 Societies, have kindly afforded facilities of access to their libraries during the 

 preparation of the Catalogue, for which the thanks of the President and Council 

 are offered. 



Acknowledgments are also due to those who have assiduously laboured on 

 the work now happily brought to completion, among whom may specially be 

 mentioned Miss Chambers and Miss Bremner, and Mr G. Griffith who has acted 

 as Editor. 



In conclusion it may be stated that the Catalogue of Scientific Papers 

 from 1883 to 1900 and the Classified Index to the first twelve volumes of 

 the Catalogue are now in hand, and that considerable progress has been made 

 with the Index. 



These volumes will close the work for which the Royal Society under- 

 took undivided responsibility. The task of cataloguing Scientific Literature 

 from the year 1901 onwards has been taken in hand by an international 

 organisation established on the initiation of the Royal Society. Through this 

 organisation various countries will cooperate in the preparation of an Inter- 

 national Catalogue of Scientific Literature. The work will be arranged under 

 Authors' names and under subjects, the subject catalogues of different branches 

 of science being issued as separate volumes. The Catalogue will be published 

 by the Royal Society acting on behalf of an International Council.
