PREFACE. THE origin and design of the following Treatise being fully set forth in the Introductory Letter, it remains only to say that the discussions contained in the volume form a series, which (should the casualties of life permit) will be probably followed at no distant time by another or others on kindred topics. A cursory inspection of the Table of Contents will show that the author has not yet touched upon a number of related questions of an interesting character, and presenting a wide field for free investigation. On some of these he hopes, sooner or later, to be able to state the views which a long and patient consideration of them has suggested to his mind. Norbury, near Sheffield, Feb. 20th, 1855.
