CATALOGUE AND INDEX OF CONTRIBUTIONS TO
NORTH AMERICAN GEOLOGY.
The scope of this work includes geologic literature published in North
America, and such literature on North America (excepting Greenland
and Central America) wherever published. Chronologically it includes
publications from 1732 to those received prior to the close of 1891.
On pages 11-14 is given a list of serials examined. It covers the
principal publications in which geologic contributions have appeared,
excepting some odd volumes which were not accessible to me. In offi-
cial literature there have been examined all the reports in Prime's
catalogue,' with some additional and all later ones. Many privately
published separate works are included, a few of which are known only
from notices in reviews or book lists. Paleontologic papers which are
purely biologic are not included, nor are papers on mineralogy in which
rocks are not described or discussed.
The entries are comprised in two classes, which are arranged in sin-
gle alphabetic sequence. They are as follows:
1. Principal entries.-These consist of full titles of separate contribu-
tions, classified by authors, with chronologic subarrangement, together
with as much of the usual bibliographic information as appears neces-
sary in a work of this kind. All composite works are segregated into
the separate contributions of individual authors as far as practicable.
The date is that of the volume imprint of the earliest regular publica-
tion of the contribution whenever possible. Accordingly, contributions
published in proceedings of societies are given the imprint date of the
volume in which they are contained. The size of the volume is given
only when it is other than octavo. The extent of papers less than a
page in length is indicated thus: († p.), († col.), (3 lines). Place of publi-
cation is given for official and separate publications and some obscure
journals. Information which I have supplied is placed within brackets.
