Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The object of this series of translations is primarily to furnish students with short, cheap, and handy text-books, which, it is hoped, will facilitate the study of the particular texts in class under com petent teachers. But it is also hoped that the volumes will be acceptable to the general reader who may be interested in the subjects with which they deal. It has been thought advisable, as a general rule, to restrict the notes and comments to a small compass; more especially as, in most cases, excellent works of a more elaborate character are available. Indeed, it is much to be desired that these translations may have the effect of inducing readers to study the larger works.
