Synopsis

Excerpt from Modern Petrography: An Account of the Application of the Microscope to the Study of Geology When the United States Geological Survey of the 40th Parallel, under Mr. Clarence King, found it necessary to have a systematic study made of its collections of crystalline rocks, there was no American prepared to undertake such a task, and the work was intrusted to Professor Zirkel of the University of Leipzig. The appearance of the results of his labors in an admirably illustrated quarto volume, entitled Microscopical Petrography of the Rocks of the Fortieth Parallel, published as Vol. VI. of the reports of the survey, in 1876, first opened the eyes of most geologists in America to the new and promising field of research. Since that time the interest manifested in this line of study in America has been steadily on the increase. The geological surveys of this country are already realizing the great value of accurate petro-graphical studies; and if, indeed, we but compare the quantity and quality of unexplored material in America with that in Europe, we must conclude that it is here that the study of rocks is destined to reach its highest development. Much that is excellent has already been accomplished on this side of the Atlantic; but the workers are few, and heretofore there has been observable too little of the rigid scientific accuracy which comes only after years of patient labor. We are, however, heirs of the past, and it is only fair that we should profit by all the accumulated experience of our predecessors. What is above all things necessary to those entering upon a line of research so difficult and new is a careful training in what has already been discovered, that labor may not be spent in vainly working out results which have already been attained by others.

Product Description

Excerpt from Modern Petrography: An Account of the Application of the Microscope to the Study of Geology

Regular instruction in petrography has for some years past been given at Harvard and Columbia Colleges; more recently, the attempt has been made at the Johns Hopkins University to organize a petrographical laboratory, where, by lectures and practical work, graduate students of geology may secure a thorough acquaintance with all the methods and results of foreign investigators. The encouragement with which this experiment has already met seems to indicate that it fills a need. Nor are signs wanting that other American universities mean to follow this lead by introducing instruc tion in petrography among their courses.
