Show On the Value of Fresh. Air. In the museum connected with the Edinburgh Ed-inburgh university is an exhibit that is a striking object lesson of the value of fresh air. A professor secured the lungs of an Eskimo, a Londoner and a coal miner. He has had them preserved by chemical process, and they are now side by side In a glass case. The Eskimo's lungs are pure white, the Londoner's lungs are a dirty brown, and the coal miner's lungs are Jet black. The Eskimo has kept Ms lungs clean, not because he knew more about breathing than the Londoner or the coal miner, but because he lived in a land of snowflelds and spent his time in the open air.
