Nor is it necessary that meat should be permanently abjured, even when
it ceases to become a daily necessity. The safer course, at least, is to
indulge the craving whenever one is 'meat hungry,' even if, as in many
cases, this be not oftener than once in several months. The rule of
selection employed in the experiment was merely to _give the benefit of
the doubt_ to the non-flesh food; but even a _slight_ preference for
flesh foods was to be followed.
