“ Pegasi through (ζ) and (θ) in the same constellation, and projected about 25 degrees, strikes (α) and (β) in Capricornus.
This constellation contains three principal stars— (α) and (β) mentioned above, and (δ) about 20 degrees east of them.
The water jar of Aquarius is about the same distance north-east of (δ) Capricorni that Fomalhaut, in the Southern Fish, is southeast of it.
(α) has a companion which can be seen by the naked eye. It is a fine sight in binoculars. These two stars are gradually separating. ”
