23 -- ------------------------------------------------------------------------ Now if our observer describe a circle, and draw a diameter inclined according to above table, this diameter would represent the sun's equator if the axis of the sun were square to the ecliptic-plane.

But this axis is slightly inclined, the effect of which is, that on or about June 10 the sun is situated as shown in fig.

14 with respect to the ecliptic _ab_; on or about September 11 he is situated as shown in fig.
13; on or about December 11 as shown in fig.

12; and on or about March 10 as shown in fig.15.The inclination of his equator to the ecliptic being so small, the student can find little difficulty in determining with sufficient approximation the relation of the sun's polar axis to the ecliptic on intermediate days, since the equator is never more _inclined_ than in figs.

12 and 14, never more _opened out_ than in figs.
