These questions and answers have been selected from about four thousand which have come to question-box of the Journal of Outdoor Life during the past ten years. This book is intended for the education of the adult or adolescent tuberculous patient. Heise aims to supplement but not to replace the advice of the attending physician. In the main, he has succeeded. In a few instances, discrepancies must have occurred, but the author is particularly careful to recognize his limitations in giving advice in absentia and insists on consultation with the physician in the settlement of many of the questions. He also admits freely the limitations of present knowledge in certain directions. A note of justifiable optimism obtains throughout, without engendering a false sense of security.
