BIBLIOGRAPHY AND INDEX OF NORTH AMERICAN 

GEOLOGY, PALEONTOLOGY, PETROLOGY, AND MINERALOGY FOR THE YEAR 1895.

By FRED BOUGHTON WEEKS.

INTRODUCTION.

The present work comprises a record of publications on North American geology, paleontology, petrology, and mineralogy for the year 1895. 

It is planned on the same lines as the previous bulletins (Nos. 130 and 

135), excepting that abstracts appearing in regular periodicals have 

been omitted in this volume.

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; 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.

most commonly cut the central stock and lainprophyres the outer zone 

of sedimentaries.
