The last column contains the value of q as obtained from 

 the distance from the earth's surface given in the Ast. Nach. 

 For the purpose of comparison, it will be seen that much 

 greater errors than those I have assumed in the place of the 

 shooting star's disappearance would be required to conciliate 

 the two results. 



We found for the instant of disappearance and for Papen- 

 burg,— 



It seems very desirable to procure other observations of 

 this kind made by two or more persons, having their time 

 sufficiently accurate to be able to identify the meteor, and by 

 each noting as accurately as possible the place of disappear- 

 ance, so that they may be enabled through the parallax of the 

 body to determine its distance from the earth. I do not see 

 in what manner isolated observations by one person can in 

 the present state of the subject tend to elucidate this interest- 

 ing question. The paper in the A&t. Nach,, to which I have 

 referred, affords ample evidence that such combined efforts 

 would in all probability be attended with success. The de- 

 termination of the distance of the body by means of its paral- 

 lax is of course independent of any hypothesis as to its na- 

 ture, and may therefore serve as a guide in any reasoning 

 upon that point.
