Late Professor o f Mineralogy in the Sheffield Scientific School o f Yale University, LSSS-1906 SECOND EDITION FIRST THOUSAND N E W Y O R K Jo h n w i l e y & s o n s Londbn: CHAPMAN & HALL, Limited 1907 IRIS - LILLIAD - Université Lille 1 Copyright, 1907 BY GRACE C. PENFIELD IRIS - LILLIAD - Université Lille 1 PREFACE TO FIRST EDITION. The minerals are arranged in the tables as follows: I. According to the six systems of crystallization and their prominent subdivisions, the minerals of each subdivision being arranged in accordance with the chemical classification as adopted b y D ana. II. According to the elements, emphasis being given to min­ erals which are important from an .economic standpoint. III. With reference to geological occurrence and association. Minerals are given three ranks in the tables, indicated by the type used in printing the names of the species, as follows:— (i) Minerals of the first rank are either very common, or espe­ cially important from a scientific or geological standpoint, and their names are printed in heavy type, capital letters. (2) Min­ erals which are of rather rare occurrence, including some very rare species provided they are especially important from an economic or scientific standpoint, are given a second rank, and their names are printed in heavy type, capital and small letters. (3) The names of rarer and less important species, constituting a third rank, are printed in small type. All of the important minerals (450 species) are included in the tables, and generally very rare species have been omitted, except where chemical com­ position or some pronounced features have given them special significance. The weighting of the minerals, or assignment to first, second or third rank, is an arbitrary matter, based upon the writer’s experience, but it is believed that students will appreciate this feature of the tables, enabling them almost at a glance to form some estimate of the relative importance of the several species.

T he “ Tables of Minerals” was written by Prof. Penfield in 1903 for use in connection with lectures on Descriptive Miner­ alogy in this School and has been used by successive classes since then. The present edition has been carefully revised, chiefly in the matter of bringing the statistics of mineral production down to date. Acknowledgment is gratefully made of the assist­ ance of Dr. George F. Kunz, who kindly furnished the figures for the values of the gem stones. Part III of the Tables has been rewritten and enlarged, with the purpose of making that section more useful to students who have only a slight knowledge of geology or petrology. W. E. Ford.

N o te .— The chief object of tables of this kind is that they may serve as a guide and reference-list to accompany lectures on crystallography and descriptive mineralogy. In a measure, also, the tables may be made the basis of determinative mineralogy, for if it is discovered that a mineral crystallizes in a certain system, the list of minerals in that system may be studied and the name of the species found by. comparison either with labeled specimens or with descriptions as given in the texts referred to. ISOMETRIC SYSTEM; NORMAL GROUP. N o te .— The pyritohedral and tetrahedral groups are tabulated separately, while a few minerals belonging to the rarer plagihedral division are included in the normal group. Elements. \ T. B. * Sys.
