Remarks - Sách nói Miễn phí

"The range of subjects treated in this book is wonderful, even to me. It is a library of universal knowledge, and the facts contained in it are different from any other facts now in use. I have carefully guarded, all the way through, against using hackneyed and moth-eaten facts. As a result, I am able to come before the people with a set of new and attractive statements, so fresh and so crisp that an unkind word would wither them in a moment." - Summary by The Author
