Now sweep from [omicron] towards [eta] with a low power.[6] There will be found a sixth-magnitude star about one-fourth of the way from [omicron] to [eta].

South, following this, will be found a group of four stars, of which one is crimson.

This is the star R Leonis.

Like R Crateris and R Leporis it is variable.
Next, let the observer turn towards the south again.

Above Corvus, in the position shown in the Frontispiece, there are to be seen five stars, forming a sort of wide V with somewhat bowed legs.
