A CATALOGUE OP OBSERVATIONS OF LUMINOUS METEORS.

11th August towards 7 a.m. This result was confirmed, it appears, by the 

 observations made by the astronomers at Rome. 



In all a catalogue of 393 meteors are given for these five evenings, with 

 the precise time of observation, apparent magnitudes, and exact positions of 

 the paths of each observation, determined by the fixed stars ; as well as 

 colours.

Professor Tachini himself observed, Avith the aid of his metcovometre, 

 which he had made use of for the 14th-November meteors of the preceding 

 year, and described in the Journal of the Observatory, No. 11 of vol. iii. 



His observations in E. A. and N. Decl. were then drawn upon a celestial 

 map, and the following results are given in relation to the radiant-point : — 



Another Table is given, showing the reductions of all the observations 

 made during the five evenings by himself aud the four other observers in 

 reference to the radiant-point : — 



Rejecting the observations of the evening of the 12th August, on account 

 of their comparative paucity, we obtain as the best average result for the 

 radiant position E. A.=43°-3, N. Decl. = -f 56°-S ; and this is probably a, 

 pretty accurate determination. 



Other meteors were seen on these evenings, which may have belonged to ^ 

 other radiants ; five seen on the evening of the 10th August had a radiant- 

 point at E. A.=3°-5-, N. Decl.= + 71°. 



The trajectories of all were in straight lines, and the streaks of the meteors 

 well marked, appearing as a slight or feeble residuum of- the substance of the 

 burning meteor itself, whose diameter generally appeared larger than that of ^ 

 the streak or train. 



Prof. A. Serpieri, of TJrbino, gives, in the monthly ' Bulletino Meteorologico ' 

 of the Osservatorio del Collegio Eaffaello, occasional observations of meteors. 

 On the evening of the 21st of May, 1868, the positions and times of seven-
