‘Mr. Marsh says, “I was looking exactly in the direction af the meteor 
and had a perfectly satisfactory view of it, and during the visibility of the 
train (20 sec.) noted with all possible care its position among the stars. 
I concluded that the track was very nearly in the line of 1 Persei and 6 
Persei, and the point of disappearance was about in a straight line joining 
8 Persei and y Andromedx,—the length of the track being about equal 
to the distance between 7 and t Persei. I continued my inspection of 
the region some time after the a of the meteor in order to 
fix the track firmly in my mind. The meteor itself lasted only one or 
two seconds, The time was about 115 23™ p,m,”
