§ 6. The diagram (fig. 1) helps us to understand the dis- 

 placement of ether and the resulting distribution of density, 

 within the atom. The circular arc marked l'OO indicates a 

 spherical portion of the boundary of the atom ; the shorter 



of the circular arcs marked # 95, '90, "20, "10 indicate 



spherical surfaces of undisturbed ether of radii equal to these 

 numbers. The position of the spherical surfaces of the same 

 portions of ether under the influence of the atom, are in- 

 dicated by the arc marked l'OO, and the longer of the arcs 

 marked '95, '90, . . . '50, and the complete circles marked 

 '40, '30, '20, '10. It may be remarked that the average 

 density of the ether within any one of the disturbed spherical 

 surfaces, is equal to the cube of the ratio of the undisturbed 

 radius to the disturbed radius, and is shown numerically in 

 column 2 of Table I. Thus, for example, looking at the 

 table and diagram, we see that the cube of the radius of the 

 short arc marked "50 is 26 times the cube of the radius of 

 the long arc marked "50, and therefore the average density 

 of the ether within the spherical surface corresponding to the 

 latter is 26 times the density (unity) of the undisturbed ether 

 within the spherical surface corresponding to the former. 

 The densities shown in column 4 of each table are the 

 densities of the ether at (not the average density of the ether 

 within) the concentric spherical surfaces of radius r in the 

 atom. Column 5 in each table shows l/Aire of the excess 

 (positive or negative) of the quantity of ether in a shell of 

 radius r and infinitely small thickness e as disturbed by the 

 atom above the quantity in a shell of the same dimensions of-
