REPORT 18G9. 



ticulars of this brilliant fireball and of the remaining large meteors, ■whose 

 real altitudes were ascertained, are described in Appendix I. of this Report.

 Erscbeinungcn von den iiltesten Zeiten bis 1866," von G. vonBoguslawski,in 

 Stettin (no date or refei'ence). — The catalogue is completed until the 12th-14th

11. " On ShoAvcr Meteors," by Dr. Edmund Weiss (Astronomische Nach- 

 richten, 'No. 1710). — On the supposition that comets must, in general, be 

 accompanied by meteoric clouds. Dr. Weiss has computed the following data 

 regarding the comets whose orbits nearly intersect the orbit of the earth, 

 either at their ascending ( £3 ) or descending nodes ( S )• The following 

 Table gives the longitude and date of passage of the earth through the comet's 

 node, the difference (at that point) of the sun's distance from the earth (E), 

 and from the comet's orbit (/•), the apparent position of the radiant-point of 

 the cometary particles, and (the tabular logarithm of) their velocity, relative 

 to the earth. 



The distance (R — )•) of the earth (at node) from the comet's orbit in the 

 direction of the sun is expressed in terms of the earth's distance from the 

 sun as imity.
