466 Dr. G. Johnstone Stoney : Survey of that part of 



Bu, the sub-section of large planetary measures, indicates 

 the place in our table in which to record the distances of the 

 planets from the Sun, or from one another, as is seen from 

 fig. 2. These distances are most conveniently read out as so 

 many metro-tens. 



The next sub-section, v, makes similar provision for repre- 

 senting the distances of the satellites from their primaries, and 

 for recording the size of the Sun, which belongs to the same 



Fig. 2.
