It appears, then, that ratios may not be combined by addi- 

 tion. 



I have elsewhere* endeavoured to show that multiplication 



IS the right rule, and that -^7- = utt" 



Multiplication, it is true, will not suit G. V.'s third assump- 

 tion (or principle, as he calls it), because it places borough 

 importance in the same predicament as any other function ot 

 two independent ratios ; but it will do better. It will arrange 

 the boroughs in the true order of their relative importance, — 

 so far as that importance depends on the ratio of their houses 

 combined with the ratio of their taxation.
