The invitation Of my publishers to have my treatise on the Rigveda (two Parts, Wissenschaftliche Beilage zum Programm der Kantonsschule in Zurich, 1878 and 1879) published in a somewhat revised and extended form, seemed to me the more to be accepted, since I had repeatedly been urged to do so from the most varied sources, and the article was frequently inquired for in the trade. It is plain that to specialists in the subject, to investigators in the field Of the Veda, it cannot offer anything really new; its aim is to embrace the results Of Vedic investiga tion, as well for beginners in the study as for all those who have a more special interest in this literature, the importance Of which is perceived and admitted in ever-widening circles, especially for theologians, philologists and historians. That, however, it is founded throughout On personal investigation Of the sources and examination Of the investigations of others will be easily perceived by every one who takes the trouble to subject the text and notes to a more minute survey.
