International Catalogue of Scientific Literature. 141 



index and schedule of classification are presented in 

 English, French, German and Italian, while entries in the 

 subject indexes may be in the language of the original 

 paper, provided it is in either Latin or one of the four 

 languages specified above. 



The original scheme of the catalogue contemplated that 

 it should comprise all original contributions to the 

 various branches of science coming within its scope, 

 whether published in periodicals, in the journals of 

 societies, or as independent pamphlets, memoirs or books. 

 While this feature is realized in the present volume, 

 financial considerations have necessitated a limitation of 

 the number of subject entries. It is much to be regretted 

 that circumstances impose this necessity upon the bureau, 

 and it is to be hoped that the difficulty may eventually 

 be overeome. This can certainly be accomplished if the 

 various periodicals Would uniformly adopt the suggestion 

 that, as is now the practice with some, all should carefully 

 index each article at the time of publication. This is a 

 very reasonable suggestion and one which, if carried out, 

 would not only enhance the value of the Journal for 

 scientific purposes, but would also greatly facilitate the 

 work of preparing the catalogue, and prove of great 

 advantage to scientific workers generally. 



The present volume embraces a total of XIV. + 373 

 pages, including special instructions to those who have 

 occasion to make use of it, and it gives great promise 

 of the wide usefulness which such a publication may 

 attain to. 



In Canada, the Dominion Government has arranged 

 for the purchase of seven copies of the Catalogue for 

 deposit in the libraries of the leading universities and the 

 Parliamentary Library at Ottawa. Individual subscribers 

 may obtain the complete set at a cost of £18, while 

 separate volumes may be had at prices ranging from ten 

 to thirty-five shillings, according to size.
