The magnitudes are 5 and 5-1/2, both being white.

Between [epsilon]^{1} and [epsilon]^{2} are three faint stars, possibly forming with the quadruple a single system.
Let us next turn to the third star of the equilateral triangle mentioned above--viz.

to the star [zeta] Lyrae.

This is a splendid but easy double.
It is figured in Plate 3, but it must be noticed that the figure of [zeta] and the other nine small figures are not drawn on the same scale as [epsilon] Lyrae.

The actual distance between the components of [zeta] Lyra is 44", or about one-fourth of the distance separating [epsilon]^{1} from [epsilon]^{2}.
