ABOUT BOOK

The first edition of this work, published early in January, 1877, contained the concentrated results of my studies during an uninterrupted residence of six years in Russia--from the beginning of 1870 to the end of 1875. Since that time I have spent in the European and Central Asian provinces, at different periods, nearly two years more; and in the intervals I have endeavoured to keep in touch with the progress of events. My observations thus extend over a period of thirty-five years.
