The second form was a homogeneous arc with a fragment of a second arc under it. This hung for some time with a steady nebulous glow between it and the one previous, as well as between the intervening periods of all. The following typical forms then were rapid and almost imperceptible gradations. The third sketch represents the same primary arc always of the same size and in the same position on the heavens: but under it are portions of two other arcs and a suggestion of a luminous horizontal line.
