[Between pp. 4, CHART I.—ISOTHERMS OF THE AIR FOR are lines drawn through points of like temperatme in degrees Fahrenheit. (After Dr. H. R. Mill.) WIND 5 denser, and thus exercises a greater pressure on thesurface, and tends to spread into the areas of lowerpressure. The air thus set in motion is wind, and thewind is part of a great and never-ceasing system ofcirculation of the atmosphere of the globe. Broadly speaking, the heating of air between thetropics and the cooling of air within the polar circlesare responsible for the whole system of atmosphericcirculation, including the movement of surface airfrom the tropics towards the poles and the returncurrents of air in the upper atmosphere. The factthat these movements are taking place, not on amotionless plane, but on the surface of a rotatingsphere, accounts for the deviation of the winds froma north and south direction. It is convenient toremember that any moving body (whether air, water,or projectile) on the surface of the Earth i
