CES RY IN presenting this work to English readers, I wish to acknowledge the kind assistance I have received from Professor Jukes and Mr. Bristow in my own country, from M. Daubrée and M. Guyerdet in France, and last, but not least, from the distinguished author, Professor Cotta himself, and from Mr. Stelzner, of Freiberg, to whose valuable assistance I owe most of what is good in the new arrangement of the Mineralogical part of the work. For the many imperfections which, in spite of much care, will probably be found, I am alone responsible. Nevertheless, I hope that this work may in some measure supply a want which has been long felt in our geological literature. I trust that allowance will be made for the difficulties of a translator if, in some instances, terms have been used in this work in a slightly extended or even different sense from that of some English authors. This has never been done without much consideration, and what appeared to me absolute necessity in rendering the meaning of my author, and in the absence of an exact equivalent for the German term in our accepted geological language.
