586 ANNUAL RKCORD OF SCIENCE AND INDUSTRY. 



Q. INDEX TO THE REFERENCES. 



In the large number of serial works received regularly 

 for use ill the preparation of material for the Record, it has 

 been found expedient to adopt some mode of abbreviating 

 the titles, so as to save both time and space in writing and 

 printing them. For this purpose the different countries have 

 been represented by letters, and the journals numbered as 

 in the following table. Publications referred to only occa- 

 sionally are indicated by abbreviations of their titles at the 

 ends of the articles. Wliere no references are made, it is 

 to be understood that the article is partially or entirely 

 original, and prepared by the editor or his collaborators; in 

 some cases, however, that the quotation has been mislaid or 

 overlooked. 



The list of works here mentioned relates simply to those 

 most fi-equently consulted especially those coming direct 

 through the post-office and forms but a small portion of 

 those passed regularly in review. The unrivaled scientific 

 library of the Smithsonian Institution is in regular and con- 

 stant receipt of the latest publications from at least one thou- 

 sand societies and establishments, public and private, in dif- 

 ferent parts of the world, all of which are used to a greater 

 or less extent by the editor and his associates in the prepa- 

 ration of the Annual JRecovd.
