plex molecular structure difficult of formation. The curve 

 of density for k =1.66, has been drawn by Lane, and the 

 corresponding integration for the potential of such a nion- 

 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
