Disturbances have recommenced in China. The insurgents were assembled at late dates at a distance of about sixty miles from Canton, with the avowed object of overthrowing the present dynasty. The Friend of China says, "His Imperial Majesty's continued possession of the throne, is quite a matter of uncertainty."

LITERATURE, SCIENCE, ART, PERSONAL MOVEMENTS, ETC.

The President of the United States accompanied by Secretaries Webster, and Graham, Attorney-General Crittenden, and Postmaster-General Hall, are at the time when we are obliged to close our Record for the month, upon a tour to the North. The main reason of this journey is to take part in the ceremonies which celebrated the successful completion of the New York and Erie Railroad—the second of those great links which bind the interior with the seaboard, the great Lakes and the West with the Atlantic and the East. They left Washington on the morning of May 12; the affairs of Government being temporarily committed to the charge of the Secretaries of the Interior, of the Treasury, and of War. At various places on the route they were welcomed with appropriate ceremonies, and reached Philadelphia in the afternoon of the same day. Here Mr. Fillmore briefly addressed the crowd from the piazza of his hotel; and Mr. Webster, yielding to repeated calls, made a speech in which he spoke of the influences that surrounded him in the State where the Declaration of Independence was pronounced, and the Constitution framed. The Union which was then formed, he said, would last until it had spread from the Pole to the Equator; and notwithstanding the dangers through which it had passed, it was now safe. On the morning of the 13th, the President and Cabinet set out for New York. At Amboy, they were received by the President and Directors of the Erie Railroad Company, in whose name Charles M. Leupp, Esq., delivered an appropriate address welcoming the Chief Magistrate of the nation, to an examination of the great work which would so largely develop the resources of the country, and continue to bind still more closely distant portions of the Union. Mr. Fillmore, in reply, spoke of the work on the completion of which he hoped soon to congratulate his native State, as one of the most important enterprises in the world. Passing up the magnificent harbor, the President and suite were received at Castle Garden as the guests of the City, by the authorities of New York; the Mayor in his address alluding to the fact that this was the first moment that the President had trod the soil of his native State as the Chief Magistrate of the nation. From Castle Garden a procession was formed, passing up Broadway and down the Bowery to the City Hall, amid the warmest demonstrations of welcome. The nature of the occasion deprived the celebration of all partisan character; the General Committees of the two great political parties occupied prominent parts of the procession. At one time there were not less than a hundred thousand spectators between the Battery and the Park. On the 14th, in company with 480 invited guests, among whom were Senator Fish, Ex-Governor Marcy, and a large number of the members of the Legislature, the President and suite left the City by a special train. All along the route, the utmost enthusiasm was displayed. At Elmira, where the train arrived at 7 p.m., the night was spent; and the following day they proceeded to Dunkirk, the terminus of the road, where extraordinary preparations had been made to celebrate the event which must result in building a large and flourishing town upon that spot.

At the annual meeting of the St. George's Society, the British Embassador, Mr. Bulwer was the principal speaker. In the course of one of his speeches he alluded to a forgery published in the American Celt, a paper published at Boston, purporting to be a copy of an intercepted dispatch from him to his Government. He used certain expressions which a portion of the residents of this City, of Celtic origin, construed into an insult to themselves and their race; whereupon they held a public meeting, and prepared a request to be transmitted to the President, asking him to procure the recall of the offending minister.

Wm. L. Mackenzie, who took a very prominent part in the Canadian rebellion of 1837, and subsequently resided for some years as an exile in this city, has been elected a member of the Canadian Parliament, beating the candidate supported by Government.

The American Association for the Advancement of Science held during the past month a very interesting meeting at Cincinnati. Among the papers read was one upon the "Azoic System of Lake Superior," by Messrs. Foster and Whitney, United States Geologists. This system derives its name from the entire absence in its structure of organic remains, and comprises the most ancient of the strata constituting the crust of the globe. Professor Agassiz characterized these investigations as conclusive evidence that we had reached the commencement of animal life, and had a starting-point from which to proceed. The only event of higher interest would be the discovery of the skeleton of the first man. Col. Whittlesey presented two skulls found in a bed of marl in Ohio. They are characterized by great deficiency in the development of the intellectual organs. The age of the skulls is calculated, from indications surrounding them, at two thousand years; thus establishing the fact of the peopling of America at a period much earlier than that usually assigned. Professor Pierce read a paper on "the Constitution of Saturn's Rings," in which he argued that these were not solid but liquid; and that no irregularities, or combination of irregularities, consistent with an actual ring, would permit a solid ring to be permanently maintained by the primary planet; and that a fluid ring could not be retained by the direct action of its primary. Saturn's rings are maintained by the constant disturbing force of its satellites; and no planet can have a ring unless, like Saturn, it have a sufficient number of properly arranged satellites. One of the most interesting papers read was the report of the committee upon Professor Mitchel's system of observing Declinations and Right Ascensions. The statements of the distinguished Western Astronomer, made last year at New Haven, were received with considerable doubt by the members of the Association. Among the foremost of the doubters was Professor Pierce, who, at the solicitation of Mr. Mitchel, was appointed Chairman of the Investigating Committee. This Committee, composed of the leading names in astronomical science, after examining his methods and apparatus, made a partial report, in which the highest and most unqualified approbation is bestowed upon the entire system adopted by Professor Mitchel. This triumph was honorable alike to the Professor and his late opponents; and the victor bore his honors with the modesty appropriate to a lover of science for its own sake. Professor Agassiz read a paper upon the coral reefs of Florida, embodying the results of recent investigations made by him, under the auspices of the United States Coast Survey.

Professor Morse has received from the Prussian Government the "Prussian Gold Medal of Scientific Merit," as a testimonial for his improvements in the Magnetic Telegraph. According to the report of the Prussian commissioner charged with the construction of telegraphic lines, Morse's telegraph has been found most efficient for great distances.

Jenny Lind has returned to New York after a Southern and Western tour of unexampled success. So meekly has she borne her honors, that even Envy would not wish them less. Castle Garden, the scene of her earliest Transatlantic triumphs, is thronged at each successive concert by appreciative audiences.

The Gallery of the Art-Union is now open. Subscribers for the ensuing year will receive a large engraving from Woodville's picture of Mexican News, and the second part of the Gallery of American Art, comprising engravings after Cropsey's Harvesting, Kensett's Mount Washington, Woodville's Old Seventy-six and Young Forty-eight, Ranney's Marion Crossing the Pedee, and Mount's Bargaining for a Horse. The Bulletin of the Union, to which members are also entitled, in addition to much valuable information on matters relating to art, will contain original etchings and wood-cuts. The number for April is embellished with a cut from Cropsey's Temple of the Sibyl, drawn on wood by C.E. Döpler, to whom we are indebted for the drawings illustrative of the Novelty Works in our last Number. It also contains one of Darley's spirited outlines, illustrative of a scene from Cooper's Prairie.

Leutze has nearly completed his second picture of Washington Crossing the Delaware, the original of which was destroyed by fire last January. It has been purchased by Goupil and Vibert, of Paris, for about $6000. It will be exhibited in Europe and the United States, and will also be engraved by François, who has so admirably rendered some of the works of Delaroche. The picture in its unfinished state has been warmly praised by German critics.
