bers of Moseley give better agreement with the pro- 

 posed relation than do the atomic ordinals of Rydberg. 

 (7) The empirical results are discussed from the view- 

 point of the quantum theory, and it is suggested that 

 the integer n may be related to the number of elec- 

 trons concerned in determining the crystalline space- 

 lattice of the element in the solid state. (8) A relation 

 similar in character is found to hold for certain elec- 

 tronic frequencies. In such cases va must be replaced 

 by j/K = 3-289 X To^® sec- ^ (Rydberg's constant). (g) 

 This relation is considered with reference to the maxi- 

 mum of the photoelectric effect, the limiting frequency 

 of this effect, ionisation potentials, and thermionic 

 potentials. — Dr. C. Chree : Historical note on a rela- 

 tion between the gravitational attraction exercised and 

 the elastic depression caused by load on the plane 

 surface of an isotropic elastic solid.
