In the pocket accompanying this work are two rings of stiff cardboard,
on which will be found all the information contained in figures 1 and 2.
When they are laid flatly upon a chart, the continuity of the lines on
the chart is not materially interfered with, while the idea of a body of
air rotating in the direction indicated by the arrows is conspicuously
presented to the mind. These rings are more particularly referred to on
page 52.
