[From the Boston Medical and Surgical Journal.]

This is a small treatise on a great subject. Its title is, "Philosophy of Health, or Health without Medicine -- a Treatise on the Laws of the Human System. By L. B. Coles, M. D." He inculcates many excellent things, which, properly observed, would lead the way to a pleasant old age, free from the infirmities that have their origin in a violation of the physiological laws. Ticknor & Co. are the publishers, who will unquestionably give an activity to its distribution over the literary world.

[From the Journal of Health.]

We rejoice in the publication of this work, for more reasons than one. First, Because the writer has advocated the same subject for which this Journal was started, and in which it has been engaged more than two years. Second, Because we see by his statement in the title page that he is a regular man, a Fellow of the Massachusetts Medical Society; and we love to see the members of a Society so respectable, and which has such vast weight on the physical welfare of the community, speaking out on these subjects. Third, Because it. advocates, in our opinion, the true ground of our obligation to the laws of our being, which are the laws of God.

Auburndale, West Newton, Ms., Oct. 4, 1848. L. B. Coles, M. D. Dear Sir:

To one who has labored, by pen or tongue, for more than a quarter of a century, to disseminate the same great laws of Health to which your own mind has been led, the appearance of a email manual, adapted to the wants of every family, cannot but be hailed with delight. I do most cordially wish to have it read, universally.

Your fellow-laborer,

Wm. A. Alcott,

The Philosophy of Health; a Treatise on the Laws of the Human System. By L. B. Coles, M. D.

We cannot be too often urged to look at the subject which the author of this little work has so carefully and judiciously unfolded. If his system is the true one, for the early care of children -- and we are very much inclined to believe that it is -- then most of the nursery discipline and maternal management of our day are very faulty. We incline to this opinion the more strongly, because the results of experience are coincident with what our author lays down as the sure consequence of so much of the mismanagement of infants and young children. There are valuable hints and directions to parents, and young persons of both sexes, which cannot fail of doing good, wherever they are appreciated and obeyed.

[From the Christian Watchman,]

The writer of the treatise which we noticed some weeks ago, on the "Philosophy of Health," has added an Appendix to the second edition, on the "Philosophy of Healthy Reproduction," in which a subject of much importance to parents, present or prospective, is treated with becoming delicacy; a perusal of which ought to prevent some of the evils often entailed by ignorance and passion on children, and children's children, to the fourth generation.

[From Zion's Herald.]

Philosophy of Health, by Dr. Coles. We have noticed before this valuable little treatise; but the present edition contains a valuable Appendix on the "Philosophy of Healthy Reproduction," which we cannot but emphatically commend. It avoids everything that the most fastidious could consider exceptionable, and abounds in most valuable counsels. The book, as a whole, combines a remarkable amount of useful information in a small compass.
