(handled in a style necessarily similar) to be found in each and all of the remaining seven Treatises. Here again is not only labor wasted by the writers--but, by the readers of the works, much time and trouble unprofitably thrown away. We say that this might have been proved _a priori_ by an inspection of the arguments of the Treatises. It has been fully proved, _a posteriori_, by the fact: and this fact will go far in establishing what we asserted in our first reason for disapproving of the subdivision--to wit: that the whole argument of the whole eight Treatises might have been readily discussed in one connected work of no greater bulk than the _Physiology_ now before us. We cannot bring ourselves to think Dr. Roget's book the _best_ of the Bridgewater series, although we have heard it so called. Indeed in the very singular and too partial arrangement of the subjects, it would have been really a matter for wonder if Dr. Whewell had not written the _best_, and Sir Charles Bell the worst of the Treatises. The talents of Dr. Roget, however, are a sufficient guarantee that he has furnished no ordinary work. We are grieved to learn from the Preface that his progress has been greatly impeded by "long protracted anxieties and afflictions, and by the almost overwhelming pressure of domestic calamity." {203} The chief difficulty of the Physiologist in handling a subject of so vast and almost interminable extent as the science to which his labors have been devoted--a science comprehending all the animal and vegetable beings in existence--has evidently been the difficulty of selection from an exuberance of materials. He has excluded from the Treatise--(it was necessary to exclude a great deal)--"all those particulars of the natural history both of animals and plants, and all description of those structures, of which the relation to final causes cannot be distinctly traced." In a word, he has admitted such facts alone as afford palpable evidence of Almighty design. He has also abstained from entering into historical accounts of the progress of discovery--the present state of Physiological science being his only aim. The work is illustrated by nearly 500 wood cuts by Mr. Byfield, and references in the Index to passages in the volumes where terms of mere technical science have been explained. Appended are also a catalogue of the engravings, and a tabular view of the classification of animals adopted by Cuvier in his "_Regne Animal_" with examples included. This Table is reprinted from that in the author's "Introductory Lecture on Human and Comparative Physiology," published in 1826. Such alterations, however, have been introduced as were requisite to make the Table correspond with Cuvier's second edition. CAREY'S AUTOBIOGRAPHY.
