Hi. A, Newton on Shooting Stars in November, 1866. 81 
reported. This is reasonable, for when the meteors are faint we 
may rightly expect a large personal equation, The average num- 
ber of observers for the two nights was probably about fourteen. 
The mean of the proportions seen by single observers for the 
two portions of the two nights was about 17 per cent. Hence 
we may say that with such observers, on meteors, and such 
modes of observing, as we had on these two nights, fourteen 
persons will see about six times as many as one person. I think 
it probable that even so large a party loses a third, or more than 
a third, of the meteors that could be seen by an indefinite num- 
ber of observers, especially when the flights are in general faint. 
While the general position of the radiant on the second night 
would seem to = the same as that given on the first night, pie 
stars moved from points nearer y Leonis. Several paths 
duced backward would cut the line joining 7 and « Leonis ian 
two or three degrees of the former star. I saw, however, no 
th that could not be referred to a radiant area of narrow 
readth in latitude. In longitude its length would have to be 
three or four degrees, unless we 
poses, that there is ” motion of the radiant. Prof. Hewitt of 
Olivet, Mich., gives a number of — = - first night that 
seem to lg fori a point nearer 7 t 
2. At New Haven.—Upon the roof of Sheffield Hall a party 
of about a students, under ni direction of Prof. Lyman, 
counted 603 meteors in five hours, from 12 o’clock onward, on 
the morning of the 13th of Noventbar. The enti is the

On the next night a similar party in the same place counted
