take food in common use, some of which is in a natural
state, others not: -
Carbonates. Nitrates.
1 lb. roasted beef,. 4 oz. 340 gr. 1 oz. 122 gr.
1 lb. milk,... 245 gr. 350 gr.
2 lbs. superfine bread, 22 oz. 370 gr.
4 lb. butter,...4 oz. 0 gr.
4 lb. sugar,.. 4 oz. 0 gr.
1 lb. potatoes,..3 oz. 145 gr.
1 lb. apples,... 3 oz. 145 gr.
41 oz. 143 gr. 3 oz. 258 gr.
In this bill one half the carbonates must be wasted.

Of the first bill, you may take of either of the
articles as much as you please without varying the
proportions of carbonates and nitrates, and consequently are in no danger of wasting food or embarrassing the system by eating too much, the appetite
being satisfied when the requisite amount of nitrates
is supplied; or you may vary the amount of different
articles, taking more of one and less of the other, without varying the proportions of the nitrates, and therefore still eat all the appetite demands. For example,
suppose, instead of a pint of milk and a pound of
bread in a day, you take double the amount of milk
and one and one half pounds of bread, you would then
get four ounces and four hundred and twenty-eight
grains of nitrates,- almost the requisite amount,
