but was met by another band of streamers making an angle 
with it, thus:

South of the zenith, however, there is a permanent arch, its 
lower edge on a and y Orionis, and at the crest its altitude is 
30° 13'*. Its upper edge passes through the Pleiades, but it 
is broader there than at the vertex. This greater breadth 
seems to be a fragment of another arch coalescing with the 
principal one, and is fading away. 
«9% 41™, The lower edge is on Aldebaran. The upper still 
on the Pleiades. 
<<‘ gh 48™, The arch suddenly becomes more luminous, The 
altitude of its lower vertex is now 34°21’. A splendid yel- 
low streamer darts along 30° of its upper edge, parallel to it, 
(which is new to me, for all that Ihave noticed hitherto were 
perpendicular to the arches or nearly so ;) with little intermis- 
sion clouds and rain, but the arch when last seen unchanged. 
© 108 35™, Clear. The arch has disappeared, but the whole 
sky is covered with flashes which are brightest to the north.” 
I may add, that the arch gave sufficient light to read the 
seconds of my chronometer and note them down, so that it 
seems impossible that Mr. Sturgeon could have failed to ob- 
serve it, had it been visible at Woolwich. If this was not 
the case, then probably the appearance which he describes 
was the dissolution of my arch, and this meteor must have 
been lower than any which I have seen. Perhaps some of 
your correspondents may be able to afford additional infor- 
mation.

* These altitudes were taken by the sextant, bringing the visible hori- 
zon’s image to the arch, and measuring its altitude (in this case 0° 51’) by 
a circle in the daylight. ,
