What more?

The cook puts in a little salt: and this the stomach takes care not
to forget either, for he is a cook who understands his business. In
the liquid of which I am speaking, there is, if not exactly salt as
one sees it at table, at all events the most active part of salt, that
which possesses in the highest degree the property of reducing
everything we eat to a paste; and this is the real reason why we find
all food so insipid which has not been seasoned with salt. As salt
contains a principle essential to the work to be done by the stomach,
some method had to be devised to induce us to provide him with it, and
this method the porter up above has hit upon. He makes a face if we
offer him anything without a little salt on it, as much as to say--"How
can you expect them to cook you properly down below, my good friend,
if you don't bring them proper materials?"

Upon which hint men have always acted from the beginning; and as far
as we can trace history back, we find them mixing salt with their food,
though without knowing the real reason why. It is the same, too, with
the lower animals. They know nothing of the matter either, but this
does not prevent their having a natural relish for salt, as any one
will tell you who has the charge of cattle; for their stomachs require
for their cooking the very same seasoning as our own, and therefore
their porter above has received the same orders.

Salt is not the only thing, however, that exists in that liquid in the
stomach. Learned men, after making minute researches, have found in
it another equally powerful material, which is also found in milk.
Therefore cheese, which contains this material as well as salt, is
quite in its place at the end of dinner. It furnishes reinforcements
