The labors of those who have edited these volumes are not only finished as far as this work extends, but if three-score years and ten be the usual limit of human life, all our earthly endeavors must end in the near future. After faithfully collecting material for several years, and making the best selections our judgment has dictated, we are painfully conscious of many imperfections the critical reader will perceive. But since stereotype plates will not reflect our growing sense of perfection, the lavish praise of friends as to the merits of these pages will have its antidote in the defects we ourselves discover. We may however without egotism express the belief that this volume will prove specially interesting in having a large number of contributors from England, France, Canada and the United States, giving personal experiences and the progress of legislation in their respective localities.
