In a previous editorial article we endeavored to show that Jaccoud is of the firm conviction that "from a therapeutic point of view the fundimental indication " for treatment of tuberculosis " should be drawn from the atmospheric pressure rather than from the temperature, and that the climates with slight and those with a moderate degree of atmospheric pressure should be specially separated. The climates belonging to the first group are all severe in winter, but differ notably from each other in atmospheric pressure, which diminishes, as. the height of the places varies from 1,650 feet, as in the more northern latitudes, to more than 4,900 feet." In the second group he places health resorts ranging in height from the level of the sea to 1,300 feet above. In these places the atmospheric pressure is moderate, " while the temperature is cool, temperate or warm in winter, hot or scorching in summer."
