It was the Spanish slaver, Leon.

The same disease had been there; and, horrible to tell, all the crew had become blind! Unable to assist each other, the vessels parted.

The Spanish ship has never since been heard of.

The Rodeur reached Guadaloupe on the 21st of June; the only man who had escaped the disease, and had thus been enabled to steer the slaver into port, caught it in three days after its arrival .-- Bibliotheque Ophthalmologique for November, 1819.
"ALL ready ?" cried the captain; "Ay, ay!" the seamen said; "Heave up the worthless lubbers,-- The dying and the dead." Up from the slave-ship's prison Fierce, bearded heads were thrust: "Now let the sharks look to it,-- Toss up the dead ones first!" Corpse after corpse came up, Death had been busy there; Where every blow is mercy, Why should the spoiler spare?
Corpse after corpse they cast Sullenly from the ship, Yet bloody with the traces Of fetter-link and whip.
Gloomily stood the captain, With his arms upon his breast, With his cold brow sternly knotted, And his iron lip compressed.
"Are all the dead dogs over ?" Growled through that matted lip; "The blind ones are no better, Let's lighten the good ship." Hark! from the ship's dark bosom, The very sounds of hell! The ringing clank of iron, The maniac's short, sharp yell! The hoarse, low curse, throat-stifled; The starving infant's moan, The horror of a breaking heart Poured through a mother's groan.
Up from that loathsome prison The stricken blind ones cane Below, had all been darkness, Above, was still the same.
Yet the holy breath of heaven Was sweetly breathing there, And the heated brow of fever Cooled in the soft sea air.
"Overboard with them, shipmates!" Cutlass and dirk were plied; Fettered and blind, one after one, Plunged down the vessel's side.
The sabre smote above, Beneath, the lean shark lay, Waiting with wide and bloody jaw His quick and human prey.
God of the earth! what cries Rang upward unto thee?
Voices of agony and blood, From ship-deck and from sea.
The last dull plunge was heard, The last wave caught its stain, And the unsated shark looked up For human hearts in vain.
