Preface 



The Committee desires to renew the record of its gratitude to the late 

 Dr Ludwig Mond, F.R.S., for his generosity in providing funds for carrying 

 on the work of the Catalogue, in which he took so keen an interest. Without 

 his help it would hardly have been possible to proceed with the Catalogue in 

 its present complete form ; by his decease the members of the Committee 

 have been deprived of a stimulating colleague who had been active in the 

 planning of the work almost from the beginning. 



The final section of the Catalogue of Scientific Papers arranged according 

 to Authors' names, that for the period 1884 to 1900, is in 'active pre- 

 paration. The material has now been all collected and it is hoped that 

 the printing may soon be commenced. 



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. 



October, 1912.
