BIBLIOGRAPHY AND INDEX OF NORTH AMERICAN 

GEOLOGY, PALEONTOLOGY, PETROLOGY, AND MINERALOGY FOR THE YEAR 1896.

By FEED BOUGHTON WEEKS.

INTRODUCTION.

The method of preparing and arranging the material of the Bibliography and Index for 1896 is similar to that adopted for the previous 

publications on this subject (Bulletins Nos. 130, 135, and 146). A 

number of periodicals and transactions of societies not heretofore 

examined are included in the present work, and are given in the list of 

publications examined. Several papers that should have been entered 

in the previous bulletins are here recorded, and the date of publication 

is given with each entry (see page 98).

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 subdivisions 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 useful minerals and 

ores described in publications examined j 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.
