Fine meteors from some of these showers often accompany the Perse'id 

 display, and will probably be recognised as diverging from certain of 

 these centres in future observations of the shower. 



Mr. Denning has also completed some reductions of various observers' 

 records of circnm-Leonid and circum-Geminid showers, of which the 

 following table gives the principal results. All the available meteor-cata- 

 logues were employed in the reductions. 



Mr. Denning draws attention to the long durations shown in this 

 table, not only of radiant-points in Leo and Leo Minor, quite distinct 

 (though less apparently so by Schmidt's determination in October) from 

 the November Leonids ; but also of three showers in Cancer, near t, /3-;', 

 and especially near o Cancri, with very fixed radiant-points, as illus- 

 trating a very commonly occurring peculiarity in such general radiant- 

 points of shooting-stars, when deduced independently from a variety of 

 sources. Such a long-continued shower Mr. Denning and Mr. Corder 

 noted in great activity from July to September, near k Persei (at 47°+ 45°) 

 distinct from, though very liable to be confused with the Perse'ids. 

 Close to this shower itself, a series of radiants indeed appears to continue 

 in prolonged activity from July to December. 



With regard to the Taurids of November and December, Mr. Denning 

 notices that a radiant deduced for December, from the Italian observa- 

 tions, (D S. XI, 13, at 64° + 15°, 7is), principally marked on December 

 6th, confirms a subradiant of the showers of Taurids I (60° -f 20°), at 

 70° + 15° (5js), which he noticed (D'77, 158) between November 25th and
