THE PERSEID METEORIC SHOWER.—The weather has been very favourable for tracing the progress of this shower. On August 10 there were not many meteors, though a few tine ones appeared. On August 11 there was a great increase in numbers, but the moon rose soon after 9 p.m. At Bristol Mr. Denning esti mated that the total number of meteors visible to one observer between 9 p.m. and 3 a.m. on the following day must have been about 150. On August 12 the rate of meteoric apparitions had declined and the num ber visible in the same time was estimated at no, but there were many detached clouds over the sky. On August 13 there were clouds at Bristol and few meteors were seen, but the Perseid shower had evidently decreased in a marked degree since the previous night. On the whole the display may be regarded as having exhibited moderate numbers with a large proportion of brilliant meteors. The radiant point showed the usual displacement to the eastward as observed on successive nights.
