BIBLIOGRAPHY AND INDEX OF NORTH AMERICAN 

GEOLOGY, PALEONTOLOGY, PETROLOGY, 

AND MINERALOGY FOR THE 

YEAR 1898. '

By FEED BOUGHTON WEEKS.

INTRODUCTION.

The method of preparing and arranging the material of the Bibliography and Index for 1898 is similar to that adopted for the previous 

publications 011 this subject (Bulletins Nos. 130,135,146,149, and 156). 

Several papers that should have been entered in the previous bulletins 

are here recorded, and the date of publication is given with each entry.

Bibliography. The bibliography consists of full titles of separate 

papers, classified by authors, an abbreviated reference to the publication in which the paper is printed, and a brief summary of the contents, each paper being numbered for index reference. The extent of 

papers less than a single page in length is indicated as £ p., 5 1. (lines).

Index. The subject headings, their subdivision and arrangement, 

are shown in the Classified Key to the Index. They comprise geographic, geologic, mineralogic, paleontologic, and petrologic subdivisions. Under Economic Geology is given a list of the useful minerals 

and ores described in publications examined; under Mineralogy, a list 

of minerals described in such publications; under Paleontology, a list' 

of genera and species of fossils therein described, and under Petrology, 

a list of rocks described, reference being made in each case, by 

author's name and number of article in the Bibliography, to the paper 

in which the fossil, mineral, or rock is described.

The Index has been added to by a list of chemical analyses of rocks 

and minerals and a list of names of geologic formations described in 

the publications examined.
