A somewhat singular controversy has arisen in reference to a body of refugees from Hungary, who have recently arrived at Liverpool. They number 262, of whom the majority are Poles, the remnant of the Polish legion in Hungary. Government wishes to send them to America, and offers a bounty of £8, to each man who will go. They wish to remain in England, evidently anticipating an uprising in some part of Europe, where their services may be called into requisition. They are entirely destitute of means of support, and in England can only maintain themselves by begging. The frigate St. Lawrence, having on board the contributions to the Exhibition from the United States, arrived at Portsmouth on the 13th of March. A meeting of the American exhibitors has been held at London, at which great dissatisfaction was expressed with many of the arrangements. They object in particular to the appointment of jurors to decide upon the merits of foreign productions; to bronze medals being awarded as prizes, when more valuable ones had been promised; to the high price of season tickets; to contributors being compelled to pay for admission, and be at the expense of their own fittings; and to the delay in affording protection to the articles which require a patent. Some leakage has occurred in the roof of the Exhibition Building; but it is hoped that it may be obviated. All opinion adverse to the suitability of the painting of the interior has passed away. The theoretical views of the decorator have been abundantly justified by the practical effect. Another expedition in search of Sir John Franklin is to be fitted out this season. The little "Prince Albert" is to be sent out, it is hoped, under happier auspices than attended her former voyage. It is expected to reach Lancaster Sound, by the middle of June. The vessel will be laid up for wintering in Prince Regent's Inlet. The party will then proceed in boats as far as practicable. When these can no longer be worked, native "kyacks" will be used, which will enable the explorers to reach a point some one or two hundred miles further than boats could carry them, as the kyacks can be hauled up and dragged over the ice. The expedition will remain out for at least one season; and a very extensive search to the westward of Boothia is proposed. It will be under the command of Capt. W. Kennedy, who has had no small experience in these icy regions. We do not learn whether Mr. Snow, from whose interesting book we copied so largely last month, is to be attached to this new expedition.
