How to Keep Well 
A Text-Book of Physiology and Hygiene for the Lower, Grades of Schools

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. All these questions, and many more, this little book will try to answer. There Will not be room to tell you all about the wonders of our bodies, but you can learn something of the story. There is, of course; much more to learn. When you know all that there is in this book you will be so interested, we hope, that you may wish to give further study to this same subject.
