The values assigned to m, &c. are entirely arbitrary, if m, m„ m„

and the labour-fund will be increased after 9 years. 



In the value of Dp tlie whole of C is supposed to be taken from 

 the labour-fund, the data necessary for calculating the effect of the 

 change enunciated in the proposition are not given.

A capitalist employs £.20000, £.7000 of which is vested in irremove- 

 able capital, and £.13000 in labour, profits being 10 per cent. He then 

 abstracts £.6500 to pay machine makers, and £ 1000 for half the profits 

 during the year the machinery is in progress. His capital is now £.6500 

 to pay wages, and £.7500 in machinery, in addition to the £.7000 irre- 

 moveable. 



The machinery is supposed indestructible, and no more is produced 

 by It than will pay the common profits on the £.7500. 



Take the capital as £.13000, and suppose that with the aid of the 

 £.7000 profits are raised on this from q-1 to <?,-l. 



Then ry,-l = ?2200. . 20

Now before the machinery was employed the produce of the £.7500 

 must have fetched 7500. y, and afterwards 7500.(^,-1);
