. anv of the ordinary stock foods, the average composition of 
lich has been ascertained. 
By allowing 8f/. per lb. for ammonia, 2d. per lb. for potash, and Money value. 
. per lb. for phosphate of lime, rates which fairly represent 
■3 present market value of these fertilising constituents, the 
lue of the manure obtained by the consumption of different 
j;icles of food may thus be estimated with sufficient accuracy 
1 be of considerable service from a practical point of view. 
■ oceeding on this basis, Mr. Lawes constructed the following 
l)le in which the estimated money value of manure from one 
ti of most ordinary articles of food is given : —
