Also, since the gain to the community may be measured bv the 

 price that would have been paid for the produce r, minus the price 

 that is actually paid for it when the profits of the capitalist have reached 

 the average rate, 



Or, this gain may be measured by the saving in expenditure, added 

 to the cost of the additional produce enjoyed, reckoning that cost at the 

 original price ; 



■ '• G = Co — A n — ^ . Co = Co . — — A as before. 



This will be an annuity in money or other produce, of which a k"' 

 part may be consumed for immediate enjoyment and a (1-^)'" part 

 used as capital, also of the former an m"' part, and of the latter an 

 )»■'" part may go to the labourer, whilst an »«'" part of the annuity 

 A after deducting the profit C{q - 1 ) is employed in the same way. 

 Before the use of the machinery the expenditure was C. 



Hence, D = C, 



D, = C -^ m \A-(q- 1) C\ - \nhk + »«,(! - k)\ G, 



D,= C - m{A-{q-\)C\ -{mje+ 'im,{l-k)}G, 



D^= C m \A-{q-l)C} -\mJe + pm,{\-k)\G
