“The whole of this paragraph must now appear a tissue of inconsequence and incoherence. All experience does not show that ‘drowned bodies’ require from six to ten days for sufficient decomposition to take place to bring them to the surface. Both science and experience show that the period of their rising is, and necessarily must be, indeterminate. If, moreover, a body has risen to the surface through firing of cannon, it will not ‘sink again if let alone,’ until decomposition has so far progressed as to permit the escape of the generated gas. But I wish to call your attention to the distinction which is made between ‘drowned bodies,’ and ‘bodies thrown into the water immediately after death by violence.’ Although the writer admits the distinction, he yet includes them all in the same category. I have shown how it is that the body of a drowning man becomes specifically heavier than its bulk of water, and that he would not sink at all, except for the struggles by which he elevates his arms above the surface, and his gasps for breath while beneath the surface—gasps which supply by water the place of the original air in the lungs. But these struggles and these gasps would not occur in the body ‘thrown into the water immediately after death by violence.’ Thus, in the latter instance, the body, as a general rule, would not sink at all—a fact of which L’Etoile is evidently ignorant. When decomposition had proceeded to a very great extent—when the flesh had in a great measure left the bones—then, indeed, but not till then, should we lose sight of the corpse. “And now what are we to make of the argument, that the body found could not be that of Marie Rogêt, because, three days only having elapsed, this body was found floating? If drowned, being a woman, she might never have sunk; or having sunk, might have reappeared in twenty-four hours, or less. But no one supposes her to have been drowned; and, dying before being thrown into the river, she might have been found floating at any period afterwards whatever.
