I. Introduction i 



Difficulty of estimating the value of atmospheric air, aside 

 from other agents in treating tubercular disease ; prevention 

 of tuberculosis; sanatoria; pioneers in the treatment of tubercu- 

 losis in America-; the Adirondack Cottage Sanitarium. 



II. Value of Forests: Micro-organisms, Atmospheric Impurities 4 



General benefit of forests; qualities of forest air and soil; car- 

 bon dioxide ; oxygen ; Ozone ; use of forest reservations for sana- 

 toria ; micro-organisms in the respiratory passages ; composition 

 of expired air ; atmospheric impurities, coal and smoke, carbonic 

 acid, sulphur dioxide, ammonia ; oxygen for tuberculous patients. 



III. Influence of Sea Air ; Inland Seas and Lakes 32 



Sea voyages; marine climate of islands ; Arctic climate; float- 

 ing sanatoria ; seaside sanatoria for children ; seacoast and fogs ; 

 fogs on the Pacific coast; radiation fogs; fogs in the moun- 

 tains; sea air for surgical tuberculosis; air of inland seas and 

 lakes. 



IV. Influence of Compressed and Rarefied Air ; High and Low Atmos- 



pheric Pressure ; Altitude 6r 



Discovery of the advantages of Colorado and California cli- 

 mate for consumptives ; works of S. E. Solly, Charles Theodore 

 Williams on Colorado; Jourdanet on Mexico; Paul Bert on 

 diminished barometric pressure, etc. ; insolation ; diathermancy 

 of the air; Alpine resorts; surgical tuberculosis treatment in 

 Switzerland ; cases of high altitude treatment ; effect of cold 

 beneficial; expansion of the thorax at the higher altitude; 

 choice of cases for treatment at altitudes. 



V. Influence of Increased Atmospheric Pressure, Condensed Air 87 



The eff^ect of barometric changes on the spirits; artificially 

 * compressed air, C. T. Williams, Von Vivenot ; pneumatic 

 cabinet; Prof. Bier's treatment of surgical tuberculosis by arti- 

 ficial hypersemia. 



VI. Artificial Pressure ; Breathing Exercises 98 



Pulmonary gymnastics; exercise at lowered air pressures; 

 atmospheric compression of the affected lung, Murphy's 

 Method, artificial pneumothorax ; song cure. 



VII. Fresh Air Schools for the Tuberculous ; Ventilation 103 



Waldschule or fresh air schools for tuberculous children; 

 Providence fresh air school; defects of school buildings; hy- 

 gienic safeguards in schools; rebreathed air; open air chapels 

 and theatres; ventilation of dwellings.
