I have, however, already faced very great dangers, and of an unknown kind; and so has that brave scholar who has helped me in the work.

As to myself, I am willing to run any risk.

For science, and history, and philosophy may benefit; and we may turn one old page of a wisdom unknown in this prosaic age.

But for my daughter to run such a risk I am loth.

Her young bright life is too precious to throw lightly away; now especially when she is on the very threshold of new happiness.
