Philadelphia, Aug. 15, 1848.

At a meeting, pursuant to public notice, of colored citizens, held on the 11th inst., at the Philadelphia Institute, for the purpose of hearing an Anti-Slavery Lecture from Wm. W. Brown, a fugitive slave from Missouri, Jas. Carter was appointed Chairman, and George W. Goines Secretary; after which Mr. Brown was introduced and took the stand, and entertained the audience with a speech, which, for earnest purpose, sound policy and faithful exposition, is rarely equalled. Mr. Brown does not abound in giddy or metaphysical metaphor, but enchains his audience with an eloquent and earnest array of matter-of-fact argument. He spoke of our condition—insisted upon the stern necessity of a high standard of self-respect—urged united action and determined purpose, to stem the torrent of popular prejudice. The colored church and clergy came in for their share of rebuke, for their apathy and indifference in behalf of the toiling bondman, and charged home upon them their recreancy in refusing to open their churches for anti-slavery lectures, and concluded by urging their imperative obligation and Christian duty.

Mr. Charles Lenox Remond was next introduced, and proceeded at once, in his usual eloquent style, to speak of the pro-slavery position that our people occupy. He demanded, in the name of justice, equity and humanity, that they open their churches, and receive the fugitive slave that had addressed them. His remarks throughout were at once sound, searching and salutary.

Mr. Robert Purvis, on being introduced, made a speech of great power, and concluded by a respectful invite to those differing in sentiment to come forward and defend them, which brought the Rev. Daniel Scott, a Baptist clergyman, to the platform, who attempted a refutation, when C. L. Remond arose, and said he recognized the voice of his once friend Stephen H. Gloucester, audibly endorsing the sentiments of the last speaker, and would most respectfully invite him to come forward and defend them. Mr. Gloucester being loudly called for, came to the stand, and said that he declined discussion for the present, but challenged Mr. Remond to meet him at a subsequent time, when he would prove that the churches of Philadelphia were anti-slavery; that his course while abroad was justifiable; and repel the charge of sacrificing principle for filthy lucre in the trial-hour of '42, by an attempt to propitiate the mobocracy by a false and contemptible communication; all of which being accepted, and Tuesday the 15th inst., at the Little Wesley Church, the time and place fixed for the discussion, the meeting adjourned.

Tuesday, Aug. 15th.—At an early hour the church was well filled, but "the cry was, 'Still they come!'" and multitudes continued to come until their was literal jam.—The excitement beggars all description. At length the men and time arrived, and the meeting was organized by appointing Dr. J. J. Bias President, and Miffin W. Gibbs Secretary.

The President stated the question to be discussed, and it was.

Resolved, That twenty minutes be the allotted time for each speaker.

Mr. Gloucester then arose, amid increasing excitement. He began by claiming an anti-slavery character for the church—endeavored to entrench himself behind the sympathies of church-members, by enumerating the good deeds of each specific church; he was evidently embarrassed, and he expressed bitter regret that he had taken the position.—(Laughing and cheering.) Mr. Gloucester did as well as men generally do when contending against the right.

Mr. Remond arose amidst great applause. He spoke of the pro-slavery position of a majority of the churches—the difficulty of obtaining churches for lectures—proved the negligence and apathy of them relative to the movement. To say the speech was powerful, eloquent and soul-thrilling, will not describe it. His opponent's points vanished before his magic touch like the early mist before the morning sun. The excitement became intense, and he was frequently interrupted by loud and continued applause. His time having expired, Mr. Gloucester reappeared, with considerable cheering from his friends, but evidently worsted by the strife. He spoke within his previous trains of argument, but they were too much shattered to present in a tangible manner, and finally concluded without adverting to his tour in the old world, and his identification with the Free Church of Scotland, or the communication of '42.

Mr. Remond closed the debate with a rejoinder, which, throughout, was interspersed with the thundering plaudits of the assembled multitude. The question being put to the house, was decided in the negative, (that they were not anti-slavery.) Mr. Jones (one of Mr. G.'s members (attempted his defence, with considerable sarcasm; when Robert Purvis obtained the floor, and portrayed in the most powerful manner Mr. G.'s faithlessness in the old world, and his recreancy in the new—

"With more of horrible and awful,

Which e'en to name would be unlawful!"

It was excoriation to the fullest extent, "without compromise, without concealment."

At the conclusion of Mr. Purvis' remarks, it was resolved to adjourn.

The excitement is yet intense, but renovating—awakening new views, and giving birth to new feelings, which,

"Tho' born like the rainbow,

'Mid thunder and storm,"

will purify the moral atmosphere, and give a felicitous zest to our common cause, for a spirit of discussion has gone forth, unbolting those doors which pro-slavery has made fast, inviting the people to honest inquiry and earnest action.

J. J. G. BIAS, Pres't.

M.W. GILLS, Sec'y.

P.S.—I would have given you a sketch of a subsequent meeting held by friends Brown and Remond, at which time the claims of the North Star were presented by Mr. Remond, and a number of subscribers obtained, which will be forthcoming through your agent, Mr. Geo. W. Goines, but my limits are already exceeded.
