It is impossible in preparing a work of this size, upon the broad
and inexhaustible subject of Education, to maintain a logical
continuity.
If my hopes in reference to the favor which this book will receive,
are half realized, the reader will, perhaps, seek some of my works
which are exclusively devoted to physical health. I take the liberty
to name "_Weak Lungs, and How to make them Strong_," and "_Talks
About People's Stomachs_;" both of which are published by Fields,
Osgood, & Co., of this city (Boston).
