I have thus set forth all that is necessary to be said here by way of preface. For various information about the treatises comprised in the appendixes, 4 the reader is referred to the preliminary notes, which preceded the translation of most of them. I have often sorely missed the presence of a competent native scholar who would have assisted me in the quest of references, and in talking over difficult passages. Such a helper would have saved me much time; but the result, I think, would scarcely have appeared in any great alteration of my versions.
