A CATALOGUE OF OBSERVATIONS OF LUMINOUS METEORS. 3881 
a half. Frequent tlashes of lightning were seen after 11" 15™ p.m., apparently 
beyond the horizon, between the north and west. Two of the brightest 
meteors, on this night, appeared at 12" 8™ and 12" 25™ a.m. of the 11th. 
On the night of the 11th the sky was clear of clouds but hazy between 
10" 15™ p.m. and 11" 35™ p.m., and meteors were not so frequent as on the 
previous night. In the half hour following midnight none were visible. 
The largest meteor observed during the display appeared at 12 25™ a.m. 
on the 11th. This meteor was as bright as Venus, of orange and green 
colour, and left in its course an emerald-green massive-looking train, 14° 
long and 6’ broad (see fig. 1). After ten seconds it assumed a serpentine 
form (fig. 2), and shortened itself some 4°. Eventually the extremities 
turned round westwards, forming the segment of a circle, almost at right 
angles to the meteor’s original course (fig. 3). It remained visible upwards 
of half a minute. ,
