80 Shooting stars of Nov. 14th, 1867. 
At 5» 18™, seven persons, counting aloud, saw 10 meteors 
in the minute. At 5" 28™ three persons saw singly in the 
minute 1, 2,1; average 1:3, At 5% 30™, four counting aloud 
saw ll inall. The dawn was at this time just beginning to 
add to the moonlight its influence in diminishing the visibility 
of the meteors. 
In order to compare the various numbers in these observa- 
tions it is necessary to reduce them to a fixed interval, and to 
allow for the cloudiness of the sky, and the numbers of ob- 
servers. For the latter purpose I have taken the numbers in 
columns B and C on page 194, vol. xli, of this Journal, com- 
bined them, and changed their form, so as to make the num- 
ber of meteors seen by a single person in a given time the 
unit. The following table is the result. 
No. of obs. Met.seen. No. of obs. Met. seen. |No. of obs. Met. seen.

The table may be interpreted thus: eight persons looking 
to divide the 
meteors as the average number seen by them individually. a 
fifteen observers will see five times as many as one. 
Making allowance thus for the number of observers, and 
the cloudiness of the sky, I have constructed from our observa- 
tions the following table. In the column “No. of meteors,” 1 
have given the number visible per minute, by a single person 
at the time indicated (N. H. m. t.) 
Table showing the number of meteors per minute visible at New Haven by a single 
observer during the night of Nov. 13th-14th, 1867.
