Preface 



The list of serials will, as in the case of Pure Mathematics, be a valuable 

 feature of the Index. It has been drawn up by the Director, and contains 

 the names of 959 serials from which the entries in the Index have been 

 taken. Each title is preceded by the abbreviation which represents the 

 serial in the Index ; the date of commencement of the serial is given, and 

 if it is extinct the date of the last volume is added. There are appended 

 symbols representing the names of twenty-eight British Libraries in some 

 of which the serials may be found ; where the set is incomplete the symbol 

 is followed by i. The information from which this list has been compiled 

 was obtained, in the first instance, from published catalogues ; subsequently 

 the list was submitted to the custodians of many of the libraries, who 

 kindly marked many serials which had not been found in the catalogues 

 used. The thanks of the Committee for this valuable assistance are due 

 to Mr F. Jenkinson of the Cambridge University Library, Mr E. W. B. 

 Nicholson of the Bodleian Library, the Librarian of the Radcliffe Library, 

 the Librarian of the Cambridge Philosophical Society, Mr F. W. Clifford of 

 the Chemical Society, to Mr R. Lloyd Praeger for obtaining information from 

 the five libraries in Dublin, Mr J. Hardy of the Royal Society of Edinburgh, 

 Mr C. V. Crook of the Geological Museum, Mr Rupert Jones of the Geo- 

 logical Society, Mr J. Knight of the Royal Philosophical Society, Glasgow, 

 Mr J. L. Galbraith of the University, Glasgow, Dr J. H. T. Tudsbery of the 

 Institution of Civil Engineers, Dr B. Daydon Jackson and Mr A. W. Kappel 

 of the Linnean Society, the Librarian of the London Mathematical Society, 

 Mr J. W. Knapman of the Pharmaceutical Society, Mr E. W. Hulme of the 

 Patent Office Library, Mr W. H. Wesley of the Royal Astronomical Society, 

 Mr F. Allen of the Royal Geographical Society, Mr R. W. Chambers of 

 University College, London, and Mr L. W. Fulcher of the Science Library, 

 Science Museum, South Kensington. 



Although much care has been expended in making this list as accurate 

 as possible, it is probable that some errors will still be found, and the 

 Director will be thankful to any one who will send corrections: portions 

 of the list will be required for the subsequent volumes of the Index.
