The first Edition of the English Translation of Maimonides Dalalātal-airin being exhausted without having fully supplied the demand, I prepared a second, revised edition of the Translation. In the new edition the three volumes of the first edition have been reduced to one volume by the elimination of the notes; besides Hebrew words and phrases have been eliminated or transliterated. By these changes the translator sought to produce a cheap edition in order to bring the work of Maimonides within the reach of all students of Theology and Jewish Literature.
