Another source of evil was added to the original crime. The colonial possessions of Spain had been broken up into republics, and those were all slave-dealers. The great colony of Portugal, Brazil, had rushed into this frightful commerce with the feverish avidity of avarice set free from all its old restrictions. North America, coquetting with philanthropy, and nominally abjuring the principle of slavery, suffered herself to undergo the corruption of the practice for the temptation of the lucre, and the Atlantic was covered with slave-ships.

But rash, ill considered, and unfortunate as was the precipitate measure of Fox, we shall never but rejoice at the abolition of the slave-trade by our country. If England had stood alone for ever in that abolition, it would be a national glory. To have cast that commerce from her at all apparent loss, was the noblest of national gains; and it may be only when higher knowledge shall be given to man, of the causes which have protected the empire through the struggles of war and the trials of peace, that we may know the full virtue of that most national and magnanimous achievement of charity to man.

It is only in the spirit of this principle that the legislature has followed up those early exertions, by the purchase of the final freedom of the slave, by the astonishing donative of twenty millions sterling, the largest sum ever given for the purposes of humanity. It is only in the same spirit that our cabinet continues to press upon the commercial states the right of search, a right which we solicit on the simple ground of humanity; and which, though it cannot be our duty to enforce at the hazard of hostility, must never be abandoned where we can succeed by the representations of reason, justice, and religion.

The curious and succinct narrative to which we now advert, gives the experience of a short voyage on board of one of those slave ships. And the miseries witnessed by its writer, whose detail seems as accurate as it is simple, more than justify the zeal of our foreign secretary in labouring to effect the total extinction of this death-dealing trade.

H.M.S. the Cleopatra, of twenty-six guns, commanded by Captain Wyvill, arriving at Rio Janeiro in September 1842, the reverend writer took the opportunity of being transferred from the Malabar, as chaplain. In the beginning of September the Cleopatra left the Mauritius, to proceed to the Mozambique Channel, off Madagascar, her appointed station, to watch the slave-traders. After various cruises along the coast, and as far as Algoa Bay, they at last captured a slaver.
