plex molecular structure difficult of formation. The curve 

 of density for k =1.66, has been drawn b} r Lane, and the 

 corresponding integration for the potential of such a mon- 

 atomic sun upon itself is given in the following table : — 



2 = 128990. 



It will be seen that the density at the center is very much 

 smaller than in the case where k= 1.4, and of course the 

 potential of the whole mass upon itself is correspondingly less 

 exhausted. Thus the monatomic sun occupies a mean place
