In regard to motive I shall say little. High professions of disinterestedness in an author's preface, seldom obtain implicit credence; and that for the best possible reason, they seldom deserve it. I shouid be pleased with a compensation for my labour, and hope that the public will find in the utility of the work, an equivalent for the expense i costs them. ROSWELL C. SMITH.
