necessarily must be, indeterminate. If, moreover, a body has risen to the surface through firing of cannon, it will not 'sink again if left 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 re-appeared 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.
"'But,' says L'Etoile, 'if the body had been kept in its mangled state on shore until Tuesday night, some trace would be found on shore of the murderers.' Here it is at first difficult to perceive the intention of the reasoner. He means to anticipate what he imagines would be an objection to his theory—viz: that the body was kept on shore two days, suffering rapid decomposition—more rapid than if immersed in water. He supposes that, had this been the case, it might have appeared at the surface on the Wednesday, and thinks that only under such circumstances it could so have appeared. He is accordingly in haste to show that
