But some of the most interesting circumstances in connection with the phenomena of November 27, 1872, remain to be detailed. Astronomers without exception regarded the display as due to the earth's passage through the _débris_ following in the path of Biela's comet. In accordance with this view Dr. Klinkerfues, of Gottingen, concluded that the comet itself, or rather its largest portion, ought to be found in the region of the heavens nearly opposite to that from which the meteoroids appeared to radiate.[27] As this point in the southern hemisphere could not be observed in Europe, he conceived the happy idea of detecting the fugitive _by means of the electric telegraph_. The following was accordingly dispatched to Mr. Pogson, Director of the Government Observatory at Madras, in Southern India: "_Biela touched earth on 27th; search near Theta Centauri_." The first two mornings after the receipt of this dispatch were cloudy at Madras. On the third, however, the cometary fragment was found, and its motion accurately measured. The observer described it as circular and rather bright, with no traces of a tail. But one fragment could be detected. On the next morning, December 3, the comet was again observed. Its diameter had sensibly increased; it had a bright nucleus, and still presented a circular aspect. A faint tail was also noticed, equal in length to one-fourth of the moon's apparent diameter. The following mornings being again cloudy, no further observations could be obtained. This cometary mass will be in close proximity to the earth about the last of November, 1892. Another brilliant meteoric shower may therefore be expected at that epoch. [27] The radiant of the Biela meteors is near _Gamma Andromedæ_. The Meteors of April 20. Meteoric showers have occurred about the 20th of April in the following years: B.C. 687 15 A.D. 582 1093 } 1094 } 1095 } 1096 } 1122 } 1123 } 1803
