Part I OBJECT LESSONS ON THE HUMAN BODY A Transcript of Lessons Given in the Primary Department of School No. 49, New York City Pupils' Edition (Revised) New York: Parker P. Simmons, Successor to A. Lovell & Company 1904 AUTHOR'S NOTE TO THE PUPIL This book has been prepared to help you in learning about "the house you live in," and to teach you to take care of it, and keep it from being destroyed by two of its greatest enemies,--Alcohol and Nicotine. As you study its pages, be sure to find out the meaning of every word in them which you do not understand; for, if you let your tongue say what your mind knows nothing about, you are talking _parrot-fashion_. And do not forget that you must pay for all the knowledge you obtain, whether you are rich or poor. Nobody else can pay for you. You, your own self, must _pay attention_ with your own mind, through your own eyes and ears, _or do without knowledge_. Be wise: gain all the knowledge you can concerning everything worth knowing, and use it for the good of yourself and other people. "KNOWLEDGE IS POWER." [Illustration: A, the heart; B, the lungs; light cross lines, arteries; heavy lines, veins.] PART I. FORMULA FOR INTRODUCTORY LESSONS. 1.
