Tho' it is evident from the above appearances that the spots on the sun’s disk vary in size, shape, and location, within short intervals, it is also evident from them that the sun has a rotating motion from west to east. The spots of Aug 29, are probably the spots of Aug 6, 23 days previous, having nearly made one revolution in past, and decreased in size.
