Firstly, how innocent are all its members. Not one of them all is poisonous. Vainly in the whole marine vegetation shall you search for one poisonous plant. Seek in every sea, and in every latitude, you will find the vegetation wholesome, genial, a blessing and a mercy. Those innocent plants ask for nothing more than to nourish or to heal animality. Many of them, the Laminaires, for instance, contain a luscious sugar; and others, as, for instance, the Corsican or Irish Moss, have a health-restoring bitter; and all, without exception, contain a concentrated and most nourishing mucilage, not a few of them saviours to the weak, worn, perishing lungs of presumptuous and ungrateful man. Where we now exhibit iodide, the English formerly used nothing but a confection of that same Corsican, or Irish, Moss. The third characteristic of that vegetation is its marvellous amorousness. We cannot doubt that if we pay the slightest attention to its strange hymeneial metamorphoses, here is the striving to be, beyond being, to be potent beyond power. We see it in the fire flies and the like small things, and we see it no less, if we will only look for it, in the sea weeds which, at the consecrated moment, seem to quit their merely vegetable life and leap into animality. Where do these wonders commence? Where are these first sketches of animality made? Where are we to look for the primitive scene of organization? Formerly these things were hotly disputed; in our own day there seems to be a certain agreement in the learned world of Europe. I can find the reply to these questions in many recognized and authorized volumes, but I prefer to borrow it from an Essay recently crowned by the Academy of Sciences, and, consequently, shielded by its high, unquestionable authority. Living creatures are found in the hot waters of eighty, even up to ninety, degrees. It is when the cooled globe gets down to that temperature that life becomes possible. The water has then absorbed, at least in part, that terrible element of death--carbonic acid gas. It becomes possible to breathe. All the seas were at first like those parts of the great Pacific Ocean, which are comparatively shallow, and are studded with small, low islets. These islets are extinct craters of by-gone volcanoes; the seaman knows them only by the summits which the slow but steadfast toil of the coral insect has upheaved from the depths. But the depths between these volcanoes are probably themselves no less volcanic, and must have been, for the first essays of primitive creation, so many receptacles of life.
