And with us, those were common elements of science which the sages of to-day disdain as wild chimeras, or despair of as unfathomable mysteries.

Even the fundamental principles, the large yet simple theories of electricity and magnetism, rest obscure and dim in the disputes of their blinded schools; yet, even in our youth, how few ever attained to the first circle of the brotherhood, and, after wearily enjoying the sublime privileges they sought, they voluntarily abandoned the light of the sun, and sunk, without effort, to the grave, like pilgrims in a trackless desert, overawed by the stillness of their solitude, and appalled by the absence of a goal.

Thou, in whom nothing seems to live BUT THE DESIRE TO KNOW; thou, who, indifferent whether it leads to weal or to woe, lendest thyself to all who would tread the path of mysterious science, a human book, insensate to the precepts it enounces,--thou hast ever sought, and often made additions to our number.

But to these have only been vouchsafed partial secrets; vanity and passion unfitted them for the rest; and now, without other interest than that of an experiment in science, without love, and without pity, thou exposest this new soul to the hazards of the tremendous ordeal! Thou thinkest that a zeal so inquisitive, a courage so absolute and dauntless, may suffice to conquer, where austerer intellect and purer virtue have so often failed.
Thou thinkest, too, that the germ of art that lies in the painter's mind, as it comprehends in itself the entire embryo of power and beauty, may be expanded into the stately flower of the Golden Science.

It is a new experiment to thee.
