“The attempt to teach only Human Physiology, like a similar proceeding in regard to Anatomy, can only end in failure; whereas, if the origin (so to speak) of the organic structures in the animal kingdom, be sought for and steadily pursued through all the classes, showing their gradual complication, and the necessity for the addition of accessory organs, till they reach their utmost development and culminate in man, the study may be rendered an agreeable and interesting one, and be fruitful in profitable results.

“Throughout the accompanying pages, this principle has been kept steadily in view, and it has been deemed of more importance to impart solid and thorough instruction on the subjects discussed, rather than embrace the whole field of physiology, and, for want of space, fail to do justice to any part of it.”—­Extract from Preface.

EXTRACT FROM PROSPECTUS.

No scientific subject can be so important to Man as that of his own Life.  No knowledge can be so incessantly appealed to by the incidents of every day, as the knowledge of the processes by which he lives and acts.  At every moment he is in danger of disobeying laws which, when disobeyed, may bring years of suffering, decline of powers, premature decay.  Sanitary reformers preach in vain, because they preach to a public which does not understand the laws of life—­laws as rigorous as those of Gravitation or Motion.  Even the sad experience of others yields us no lessons, unless we understand the principles involved.  If one Man is seen to suffer from vitiated air, another is seen to endure it without apparent harm; a third concludes that “it is all chance,” and trusts to that chance.  Had he understood the principle involved, he would not have been left to chance—­his first lesson in swimming would not have been a shipwreck.

The work will be illustrated with from 20 to 25 woodcuts, to assist the exposition.  It will be published in monthly numbers, uniform with Johnston’s Chemistry of Common Life.

Whoever misses reading this book, will miss reading what is, in various respects, to the best of our judgment and experience, the most remarkable book of the day—­one, indeed, that no thoughtful, inquiring mind would miss reading for a good deal.  Let the reader be as adverse as he may to the writer’s philosophy, let him be as devoted to the obstructive as Mr. Buckle is to the progress party, let him be as orthodox in church creed as the other is heterodox, as dogmatic as his author is sceptical,—­let him, in
