This work is an original and thorough examination of the fundamental laws of Moral Science, and of their relations to Christianity and to practical life. It has already taken a firm stand among our highest works of literature and science. From the numerous commendations of it by our most learned and competent men, we have room for only the following brief extracts:

From the Rev. Thomas H. Skinner, D. D., of the Union Theol. Sem., N. Y.

"It is a work of uncommon merit, on a subject very difficult to be treated well. His analysis is complete. He has shunned no question which his purpose required him to answer, and he has met no adversary which he has not overcome."

From Rev. L. P. Hickok, Vice-President of Union College.

"I deem the book well adapted to the ends proposed in the preface. The style is clear, the thoughts perspicuous. I think it calculated to do good, to promote the truth, to diffuse light, and impart instruction to the community, in a department of study of the deepest interest to mankind."

From Rev. James Walker, D. D., President of Harvard University.

"Having carefully examined the more critical parts, to which my attention has been especially directed, I am free to express my conviction of the great clearness, discrimination, and accuracy of the work, and of its admirable adaptation to its object."

From Rev. Ray Palmer, D. D., of Albany.

"I have examined this work with great pleasure, and do not hesitate to say that in my judgment it is greatly superior to any treatise I have seen, in all the essential requisites of a good text-book."
