15. Taking the volume of: the unit of positive 

 electricity in absolute dimensions as above obtained, a fair 

 approximation to the absolute radius of the out>ide ring can 

 be made. Having thus found two points on the line repre- 

 senting this series, its position is determined. It is to be

noticed that all the spectrum lines in this series are not 

 caused by the outside ring of electrons. Al, Si, and P are 

 attributed to the outside ring; S, CI, and A to the second 

 ring ; K, Ca, Sc, and Ti to the third ring; V, Or, Mn, Fe, 

 and Co to the fourth ring ; Ni, Cu, Zn, Ga, Gre, As, Se, and 

 Br to the fifth ring; Kr, Rb, Sr, Y, Zr, Nb. Mo, and 

 possibly a few more to the sixth ring. In a similar manner
