CX. The Hydrogen Molecule. III. 

 By Albert 0. Crehore *. 



IN the preceding paper f (IE.) the case of two h} r drogen 

 atoms of the kind described J in the first paper (I.) 

 was treated in the special position where the two atoms are 

 so aligned as to have a common axis, anil the forces acting 

 along this common axis alone were computed. A stable 

 equilibrium in this direction was found when the distance 

 between the atoms is 1*18 X 10~ 8 cm. Since this problem is 

 typical of that with other forms of more complicated atoms, 

 it seems important to investigate the character of the whole 

 field around the central atom as affecting a second atom. 

 The method followed in the previous paper has been applied 

 here to cover the general position in space, always keeping 

 the axes of revolution of the two atoms of hydrogen parallel, 

 but no longer coincident or coaxial. 



The only two forces that have any existence with this form 

 of model are the electrostatic force together with the force 

 due to the revolution of the positive and negative charges 

 (electrons) upon their axes. The latter was completely 

 developed in the first paper cited, equation (57), and may 

 be called the gravitational attraction. It has been shown 

 that no terms of higher order than the inverse square can be
