160 Catalogue of Chemical Periodicals. 



eiitific and Technical Periodicals, 1665-1882/' published by the 

 Smithsonian Institution, includes works in every department 

 of pure and applied science, and to this comprehensive work we 

 refer librarians and others seeking a wider range. The data 

 in the following pages have been drawn in great measure from 

 the larger catalogue just named ; the works have been brought 

 down to a later date, and society journals have been introduced. 



That no bibliography of periodicals which can be classed as 

 chemical, will contain all the literature of chemistry, goes with- 

 out saying ; chemical papers are unfortunately widely scattered 

 in society publications and in serials devoted to general science ; 

 to include all these is of course out of the question, but a 

 few have been admitted to this list. For a more complete bibli- 

 ography we refer for society journals to the " Catalogue of Sci- 

 entific Serials" of Mr. S. H. Scudder (Cambridge, 1879, 8vo), 

 and for journals of general science to our oavh "Catalogue" 

 already mentioned. 



Plan of Catalogue. — The arrangement of titles is strictly alpha- 

 betical, the articles and the adjective New alone excepted. The 

 different titles borne by a periodical at different periods, are 

 arranged in chronological order under the first or earliest title. 



Cross-references have been freely introduced, and are of three 

 kinds : 1st, from the later to the first title of a periodical which 

 has undergone changes in title ; 2d, from short titles in common 

 use to the accurate bibliographical designations ; 3d, from the 

 names of editors to the periodicals conducted by them. Besides 

 these, in the case of societies, references are made from the cities 

 in which the societies are located, and from the proper designa- 

 tion of the societies to the titles of the journals published by 

 them. A geographical index, arranged by counties and cities, 

 will be found at the close.
