Preface 



and Mr G. Harold Wilson. The Committee is indebted to them for much 

 valuable help. 



The arrangement of the contents of this volume for the press has been 

 made by Mr R. J. Dallas, M.A., of King's College, Cambridge. To him, and 

 to Miss Bremner and the other members of the Catalogue Staff of the Royal 

 Society, thanks are due for careful and conscientious work. Mr G. B. 

 Mathews, F.R.S., a member of the Committee in charge of the Catalogue, 

 and the officers of the Royal Society, have given help from time to time 

 about questions of arrangement. 



The material for the Index volume for Physics is already in an 

 advanced state of preparation ; this is largely owing to the interest which 

 Dr Ludwig Mond, F.R.S., has continued to take in the work, and the in- 

 creased subsidy by which he has most generously made acceleration possible. 



The Catalogue of Scientific Papers arranged under Authors, for the 

 period 1884 to 1900, is in preparation; the material will not however be 

 quite complete until the Subject Indexes for the various Sciences have 

 been reduced to order. 



The Syndics of the Cambridge University Press have undertaken the 

 complete risk of printing and publishing, as regards both the Catalogue of 

 Scientific Papers and the Subject Index. It will be the care of the Com- 

 mittee, and it is hoped of the Scientific world generally, to use their best 

 endeavours that this public-spirited action shall not result in financial loss. 



The thanks of the Committee are due to the officials of the Cambridge 

 Press for their unfailing courtesy in the discharge of a complex task. 



November, 1909.
