number of meteors per minute observed at Greenmch, on the 13th-14th of 

 November, between the hours of 11 p.m. and 4 A.ir. Besides four principal 

 maxima of frequency at 12'' 40", 1" 10", 1" 20", and 1" 50" a.m., two other 

 smaller maxima are seen to have occurred at 2'' 4.5" and '3^ 45" a.m. The 

 Greenwich observations, in extenso, are printed in the Greenwich ' Results of 

 Magnetical and Meteorological Observations ' for the year 1866. 



At the Eoyal Observatory, Greenwich, Mr. J. W. L. Glaisher recorded 

 a number of the apparent paths of the meteors, amply sufficient to determine 

 the positions of the principal radiant-point in Leo, and of two others of less 

 consequence, one in Gemini and the other in Perseus. 



Among the tracks of meteors recorded by Mr. Glaisher's staff of observers 

 at the Royal Observatory, about sixty of the apparent paths were projected
