but also a great purifier and revivifier of the earth and sweetener of the atmosphere. God is the great first cause of all that is and that operates in the universe. It were an act of presumption to inquire into what we may term the first acts of the Almighty's power. But there is no presumption—on the contrary there is propriety, as well as the highest gratification of which the human mind is capable—in penetrating through the paths of knowledge up to that first series of second causes which circle like a glory round the fountain-head. We may not put the question, "How did God create all things out of nothing?" but, all things having been created, it is quite legitimate to inquire how the circles of their manifold operations are carried on, and in what respect the things that be do affect each other.
No book that has of late years issued from the press treats more eloquently and interestingly of such subjects of inquiry than that admirable work of Captain Maury of the United States Navy, entitled "The Physical Geography of the Sea." Much of the substance of what we have written has been culled from the pages of that fascinating volume. But we have merely plucked one or two leaves, as it were, and presented them to our readers in the hope that they may be tempted by their fragrance to pluck the flower. The mysteries of the atmospheric and aqueous oceans are here treated of fully, yet so agreeably, that one is frequently apt to fancy one is perusing the pages of romance.
