POPULAR SCIENCE REVIEW. 
first it occurred to me to place two observers, one looking 
towards the region of the radiant point, and the other towards 
the opposite region, but I found that the attempt to carry into 
effect this arrangement introduced confusion. I therefore 
directed the observer always to keep the star 7 AndromedoR as 
the centre of vision, and to continue counting as many meteors 
as he could without turning round. The counting of the 
meteors commenced at 5h. 30m., and was prosecuted without 
intermission until 11 h. 50m.; it consequently embraced an 
interval of 6h. 20m. The operation was effected by counting 
the number of meteors visible in each successive interval of 
five minutes. The meteors counted were thus parcelled out 
into seventy-six groups, each group extending over five 
minutes. The number of meteors counted in the first group 
(5h. 30m. to 5h. 35m.) amounted to 40. The number of 
meteors in the maximum group (8h. 10m. to 8h. 15m.) was 
367. The number of meteors in the last group (llh. 45m. to 
llh. 50m.) fell to 6. Taking the first seventy-two groups, and 
forming them into twenty-four groups of fifteen minutes each, 
we have the following results : —

“ It is clear that the maximum of the shower occurred about 
8h. 10m. The aggregate number of meteors counted from 5h. 
30m. to llh. 50m. (by one observer) amounted to 10,579.” 
To this it may be added that in Italy the shower was even 
richer, for Signor Denza states that in 6|- hours no less than 
33,400 meteors were counted by four observers. The meteors 
were very brilliant,” he adds, “ and were noticed in every part 
of the sky. The number recorded above is far less than the 
truth, for we found it frequently impossible to count them. 
The maximum display took place between 7h. and 9h., and for 
21 minutes, between 6h. 35m. and 6h. 56m., the appearance in 
the sky was that of a meteoric cloud. The radiant point was 
very clearly indicated near 7 Andromedce, 
Now in the first place it is to be noticed that there can be 
no question whatever as to the meteoric display having been
