affected by the Earth. 253 
_ Turning now to the effects in the plane E's ¢, we find the ele- 
ments in part for the meteors above designated as mm on the 
side ing, and rr on the side following ; viz. : 
Transverse axes, 151 and 
Perihelion distances, 0°47 and 0°72 
This Saher therefore expands the ring to an extreme 
breadth at the ascending nodes of about twenty-four millions of 
miles, and—admitting the sufficient exactness o 
throws it closely up to the orbit of Venus. It will be remem- 
that the meteors which have the extreme perihelion dis- 
tance have also the higher latitude and elevation for the radiant 
at the earth. 
Therefore in th hrown forward by the 
e plane Es ¢ the nodes are throw } 
Small distances “7 n’ o’ which are nearly equal. Moreover this 
distance is the same, very nearly, for rr as for pp, 
* The small reduction to the ecliptic may be neglected.
