James Lewiston reported 25 per minute for one observer at 5^ h ; 

 at 6 h 100 in a minute were counted; at 6 h 20 m a decrease was 

 noted; at 6 h 38 m they had risen to 70 per minute; thereafter the 

 numbers gradually diminished. The radiant was fixed at R. A. 

 21°, Decl. 44°. Professor Pritchard at Oxford, counted 251 mete- 

 ors between 6 h 34 ra and 6 h 39 m , and 305 between 7 h 14 m and 1 h 

 19 m . Mr. Gr. J. Symons says that the meteoi-s in 1866 were both 

 more numerous and larger than in this shower. He computed 

 the whole number falling at 8 h 5 ra as over 3,000 per hour. 



An adequate discussion of the shower can be made only when 

 all the reports are received. h. a. n.
