The components of [zeta] are very nearly equal in magnitude, in colour topaz and green, the topaz component being estimated as of the fifth magnitude, the green component intermediate between the fifth and sixth magnitudes.
We may now turn to a star not figured in the map, but readily found.

It will be noticed that the stars [epsilon], [alpha], [beta], and [gamma] form, with two small stars towards the left, a somewhat regular hexagonal figure--a hexagon, in fact, having three equal long sides and three nearly equal short sides alternating with the others.

The star [eta] Lyrae forms the angle next to [epsilon].

It is a wide and unequal double, as figured in Plate 3.

The larger component is azure blue; the smaller is violet, and, being only of the ninth magnitude, is somewhat difficult to catch with apertures under 3 inches.
The star [delta]^{2} Lyrae is orange, [delta]^{1} blue.
