midnight
Worship me as much as you like ; it keeps you out of mischief . But you might change the tune now and then , and give me some of your alleged wisdom . '' `` Shall I becloud that pure and youthful brow with metaphysic fumes ? Should I soil your dainty muslins with the antique dust of folios , and oil from the midnight lamp ? You wait till you take up Hartman ; perhaps you can stand it from him . But if I were to hold forth to you in the style he prefers , you would get sick of me in twenty minutes . Let it suffice that my lonely vigils are spent in severe studies and profound meditations , the fruit whereof , in a somewhat indirect and roundabout way , may make smooth and safe the path that is traversed by your fairy feet .
