Haughton ( 2 ) as a result of his researches adopted the same figure 

 while Coulomb calculated the ratio to be 18. 



In the great majority of cases a ratio of 16 : 1 is probably the 

 most accurate approximation that can be made. 



Adopting this ratio a man weighing 65 kg. does 65 metre-kilo- 



Sif* 



grammes per metre, or = 4 kilogrammetres approximately. 



Hence a pace -8 metres long is equivalent to 4 X -8 = 3-2 kilo- 

 grammetres, a much lower value than that deduced by the graphi- 

 cal methods of para. 272. By this method the efficiency of 

 ordinary walking would be calculated to be 32%.
