The preface declares : This book is not a new presentation . . . but is simply a compilation, and in some sense an abstract, of the various writings of Mrs. White upon this subject (health), to which have been added several articles by Elder James White elucidating the same principles.. . . The work of compilation has been done under the supervisionof Mrs. White, by a committee appointed by her for the purpose,and the manuscript has been carefully examined by her.The purpose in the preparation of this volume has been to gathertogether, in a condensed form, writings which were scattered through various volumes, and some that have never before appeared in print.The E.G.W. section comprises eighteen chapters and a group offragments. She later amplified the principal chapters and made them the body of The Ministry of Healing ( 1905). ' Nine chapters, in whole or in part, were incorporated into Counsels on Health (1923) or Fundamentals of Christian Education ( 1923).
