LETTER OF TRANSMITTAL.

DEPARTMENT OF THE INTERIOR, 

UNITED STATES GEOLOGICAL SURVEY,

DIVISION OF GEOLOGY, 

Washington, D. 0., October 22\ 1895.

SIR: I have the honor to transmit herewith the manuscript of a 

Bibliography and Index of North American Geology, Paleontology, 

Petrology, and Mineralogy for the year 1894, by Mr. F. B. Weeks, 

with the recommendation that it be published by the Survey. It is 

planned on the same lines with that for 1892-93, by the same author, 

and bears evidence of the same careful preparation. 

Yery respectfully,

S. F. EMMONS,

Geologist. 

Hon. CHARLES D. WALCOTT,

Director United States Geological Purvey.

BIBLIOGRAPHY AND INDEX OP NORTH AMERICAN 

. GEOLOGY, PALEONTOLOGY, PETROLOGY, AND MINERALOGY FOR THE YEAR 1894.

By FRED BOUGHTON WEEKS.

INTRODUCTION.

This work is a continuation of the Bibliography and Index for 1892 

and 1893 (Bulletin No. 130), and records the papers on North American 

geology, paleontology, petrology, and mineralogy published in the year 

1894, almost all of. Avhich appeared in the serials composing the List 

of Publications Examined, immediately following.

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.
