Elements of Morality and Polity.

BY WILLIAM WHEWELL, D.D.,

AUTHOR OF "HISTORY AND PHILOSOPHY OF THE INDUCTIVE SCIENCES," &c.

2 vols. 12mo, Muslin, extra gilt, $1 00.

Dr. Whewell's work ought to be read, because it can not be read
without advantage: the age requires such books.--_London Athenaeum._

A text-book of simple truths, from which, by induction, a complete
system of morality is constructed, applicable to all the relations
and circumstances of life, and embracing every department of human
action. The reader who shall carefully study these volumes--and a
more inviting page, clear and legible, the eye does not often rest
upon--will find his labor more than rewarded.--_New York Commercial
Advertiser._

Professor Whewell's "Elements of Morality" have been universally
received in England as a contribution of rare value to the department
of moral and political science.--_Baltimore American._

A splendid production by one of the most distinguished of the
scientific men of the age. This is a book, not to be read merely, but
to be re-perused and patiently studied, we have heard it pronounced by
no mean critic the most complete and lucid work on ethical philosophy
ever produced. We commend this work to the especial notice of thinkers
and readers, to scholars and schools generally, as a most admirable
text-book--_Sun._

The style of the work, though simple, is extremely clear, strong, and
eloquent. It is a book to be _studied_ rather than superficially read,
and can not fail to be of the very highest importance in instructing
and disciplining the public mind.--_American Patriot._

This is beyond all comparison the most complete, comprehensive, and
luminous treatise on the important subjects it discusses, that is to
be found in the language, and its careful study is indispensable to
every one who would obtain true and definite notions in regard to the
principles of public and private morals. It is profoundly learned
and philosophical, but the writer thinks logically and clearly,
and is therefore at all times lucid and comprehensible.--_Buffalo
Commercial Advertiser._

The Philosophy of Mystery.

This is a learned and elaborate work, in which the writer goes
into the investigation of all the phenomena of mind in the erratic
operations and phantasies of ghost seeing and spectral hallucinations,
and aims to give the t
