 of the American Medical Association, The American Public Health Association, Societe 

 D'Hygiene of France, British American Association for the Advancement of Science, Michigan 

 State Board of Health, etc. 

 The design of this book is to present, in as simple a manner a-; possible, such hygienic and physiological facts as are 

 necessary to give to children a knowledge of the LAWS (IF HEALTHFUL LIVING. So far as possible technical terms have 

 been avoided, and no matter has been introduced which has not practical reference to the preservation of health. The 

 subject of Narcotics and Stimulants receives due attention, and is treated in such a manner as to adapt the book to the 

 requirements of recent laws relating Xn temperance in the public sclvwls. The language, so far as possible, is clear and 

 simple, and definitions and statements are presented in a style suited to the comprehension of children, and cal- 

 culated to arouse their interest in the subject studied. 



Price for examination or introduciion, 33 cents ; list piice, 40 cents.

 adapted to SELF-INSTRUCTION, — of a REVOLU- 

 TIONARY SYSTEM, that discards the indefinite (vow-

 radical innovation, EXACTNESS with BREVITY. 

 Specially adapted to Legal and other Technical work. A 

 phonographic author writes of it : — '" On technical mat- 

 ter, you are ahead of any form of Pitman's phonog- 

 raphy." The author claims equal superiority on covi-

 of BREVITY, where the old phonography makes no dis- 

 tinction. A MODKRN WORK, ADAP TED to MOD- I

 and precision than by any of the older systems."
