trials, strength to perform our appointed work; and whoever may think fit to make these the subjects of statistical inquiry, may depend upon being assured by everyone experimentally qualified to reply, that they are never asked for faithfully without being obtained effectually; together with large measure, if not of the cheerfulness, at least of the patience, of hope.

Thou knowest that I sought not to draw nigh Thy Throne, save that my witness might record More truly of Thine attributes, whereby On Earth, e'en as in Heaven, might be adored The fulness of Thy glory. Not in wrath His trespass wilt Thou judge, whom, licence, bred Of zeal, though blinded, yet devout, betrays, Nor scorn the unconscious wanderer from Thy path, Nor leave me hopeless, if indeed misled By thirst for truth, more deep in error's maze.
