The inherent difficulty in the experiment of special and appropriate

co-education is the difficulty of adjusting, in the same institution,
the methods of instruction to the physiological needs of each sex; to
the persistent type of one, and the periodical type of the other; to
the demand for a margin in metamorphosis of tissue, beyond what study
causes, for general growth in one sex, and to a larger margin in the
other sex, that shall permit not only general growth, but also the
construction of the reproductive apparatus
The inherent difficulty in the experiment of special and appropriate

the demand for a margin in metamorphosis of tissue, beyond what study

other sex, that shall permit not only general growth, but also the
construction of the reproductive apparatus. This difficulty can only
be removed by patient and intelligent effort. The first step in the
direction of removing it is to see plainly what errors or dangers lie
in the way. These, or some of them, we have endeavored to point out.
'Nothing is so conducive to a right appreciation of the truth as a
right appreciation of the error by which it is surrounded.'[32] When
we have acquired a belief of the facts concerning the identical
education, the identical co-education, the appropriate education, and
the appropriate co-education of the sexes, we shall be in a condition
to draw just conclusions from them.
