It may be well to refer for a moment to the variations in

temperature known as inversions
It may be well to refer for a moment to the variations in
temperature known as inversions. In the accompanying diagram
it will be seen that the temperature falls with elevation, and
starting from the ground on a day when the temperature is near
the freezing point, 273 degrees A., one finds at a height of
seven thousand meters a fall of about forty degrees. It is not
easy to represent on a single diagram the variation in detail
and therefore we have divided the air column into three parts,
the scales being as one to a hundred.
