The writer of this sketch was chosen Chairman of the meeting, and commenced its proceedings by delivering the following address, which we cut from the columns of the Morning Advertiser:—­

“The Chairman, in opening the proceedings, remarked that, although the metropolis had of late been inundated with meetings of various character, having reference to almost every variety of subject, yet that the subject they were called upon that evening to discuss differed from them all.  Many of those by whom he was surrounded, like himself, had been victims to the inhuman institution of Slavery, and were in consequence exiled from the land of their birth.  They were fugitives from their native land, but not fugitives from justice, and they had not fled from a monarchical, but from a so-called republican government.  They came from amongst a people who declared, as part of their creed, that all men were born free, but who, while they did so, made slaves of every sixth man, woman, and child in the country (hear, hear).  He must not, however, forget that one of the purposes for which they were met that night was to commemorate the emancipation of their brothers and sisters in the isles of the sea.  That act of the British Parliament, and he might add in this case with peculiar emphasis, of the British nation, passed on the 12th day of August, 1833, to take effect on the first day of August, 1834, and which enfranchised 800,000 West Indian slaves, was an event sublime in its nature, comprehensive and mighty in its immediate influences and remote consequences, precious beyond expression to the cause of freedom, and encouraging beyond the measure of any government on earth to the hearts of all enlightened and just men.  This act was the commencement of a long course of philanthropic and Christian efforts on the part of some of the best men that the world ever produced.  It was not his intention to go into a discussion or a calculation of the rise and fall of property, or whether sugar was worth more or less by the act of emancipation.  But the abolition of Slavery in the West Indies, was a blow struck in the right direction, at that most inhuman of all traffics, the slave trade—­a trade which would never cease so long as slavery existed, for where there was a market there would be merchandise; where there was demand there would be a supply; where there were carcases there would be vultures; and they might as well attempt to turn the water, and make it run up the Niagara river, as to change this law.  It was often said by the Americans that England was responsible for the existence of slavery there, because it was introduced into that country while the colonies were under the British Crown.  If that were the case, they must come to the conclusion that, as England abolished Slavery in the West Indies, she would have done the same for the American States if she had had the power to do it; and if that was so, they might safely say that the separation of the United States from the mother
