PARABOLIC ORBITS OF METEOR STREAMS. 



By CHARLES P. OLIVIER. 



REPORT OF THE AMERICAN METEOR SOCIETY FOR 1911-1913. 



Having been personally interested in meteors for many years, the idea 

 came to the author during 1911 that it might be possible to form an organ- 

 ization whose purpose should be to advance meteoric astronomy in all 

 possible ways by the cooperation of persons interested in their observation. 

 Out of this grew the American Meteor Society. Some of the members 

 have contributed valuable work, while as yet others have sent in little or 

 nothing. 



Most especial acknowledgment must be accorded to the Society for 

 Practical Astronomy, because it was through being appointed director 

 of its Meteor Section that I have been able to secure the assistance of 

 most of our best observers, who are also members of that society. It 

 must therefore be understood that all work done by such members (des- 

 ignated thus *) must be accredited first of all to the Society for Practical 

 Astronomy, and it gives me the greatest pleasure to make this acknowl- 

 edgement. Below is the list of such members as have contributed work to 

 date :
