Excerpt from The Determination of Rock-Forming Minerals: With One Hundred and Three Woodcuts The following authorized translation of Dr. Hussak's work was undertaken with the view of supplying a want felt in our colleges and universities. Though great progress has been made in the sciences of mineralogy and lithology in later years, through the study of the optical and the other physical properties of minerals, few attempts have been made to con dense the exhaustive and original articles scattered through the scientific periodicals and State and national publications, and to put them in suitable shape for use in the laboratory and the class-room. It has been the aim, therefore, to place before the American student a practical work which shall describe the methods and exhibit the results of such investigations. The translation of a technical work of this character is beset with difficulties appreciable only by those who have under taken a similar task. Few liberties have been taken with the text, and the attempt has been made to reproduce the original literally so far as possible, at points, however, in order to convey clearly the author's meaning, some recasting of sentences was unavoidable.
