These portions emitted a bright light, and were separated by faintly luminous spaces. At 1 Ih., the arch, having nearly the same direction as before, was composed throughout the greater part of its length by two parallel portions, each gra- dually fading away towards their edges ; and the end of the arch was also lengthened out, and bent towards the east, so as to come in contact with the mass of light noticed above as bearing This bent portion of the arch was composed of several bars nearly of equal length, and arranged so that every succeeding one lay to the north of that which preceded it in their approach to the horizon: the whole were connected together by a faint diffused light; and from the same body of light in which that end of the arch now terminated, a column of faint beams rose perpendicularly to the height of 15°. At 1 Ih. 20' the arch had increased its breadth to 20°, its northern edge being very near the zenith. Its extremities, bearing and N. W., were composed of irregular, and somewhat detached roundish, masses, but its centre consisted of five bright longitudinal bands connected by a faint diffused light. The mass of light formerly bearing , had now moved round towards the south, and still resting in the hcrizon, formed the end of the arch. At midnight, a great number of detached masses of light occupied the sky from 20° south to 10° north of the zenith. These masses of light varied in shape, but the greater number had somewhat of an oblong form. They were separated in some places by clear blue sky, in others they were connected by a diffused light. They lay in various d
