The annual periodicity of this phenomenon, its duration, and the manifest 

 ctovergence of the paths of the meteors, would accord well with the hypothesis 

 of a revolving belt or zone of meteors, rvhose centre is the sun, and whose orbit 

 passes very near to the orbit of the earth, piercing the plane of the ecliptic in the 

 signs Aquarius and Leo. The plane of its orbit, according to the computations 

 of Mr. Erman, is quite beyond the limits of the zodiac, being inclined to the
