OBSERVATIONS OF LUMINOUS METEORS.

 of November may succeed in distinguishing this new shower from those 

 of Taurids I and Taurids II (at 80° + 23°).

An elaborate paper of reductions of the observed paths of 2,450 

 shooting-stars, of the first 20 days of November, by Herr Louis Gruber, 

 of the Imperial Observatory of Vienna, was communicated last year to 

 the Academy of Sciences of Buda-Pestb, and it also forms an appendix 

 in the January number of the ' Memorie degli Spettroscopisti ltaliani.' 

 From the miscellaneous collection of these meteor-tracks, Herr Gruber 

 extracts the following places and durations of twelve November radiant- 

 points, of which he also indicates in some measure the characters of 

 importance. As the paper is of some length, and the conclusions drawn 

 from it are of considerable interest, the Committee is obliged in the present 

 notice to confine itself to this indication of its value, and to an acknow- 

 ledgment for its obliging communication to the author.

 Sawyer of Boston, and by other observers ; of papers of great interest
