In the course of the debate a singular discussion arose, which tends to throw some light upon the management of the Colonial Office. A most important despatch upon the state of Jamaica had been received from Governor Grey, and this was withheld from the select committee then sitting, although Mr Hawes, the Under-secretary for the Colonies, was directly questioned as to its existence. We do not wish to enter into the details of this matter, or to cast any imputation upon the probity of Mr Hawes, who, in explanation, was fain to take shelter under the plea of a mistake. But the circumstance certainly did look awkward, and the doubts, not only of the House but of the country, were far from being removed by the extreme acrimony displayed by the Premier, in his injudicious defence of his subordinate. Never in our recollection has a Prime Minister shown so remarkable a want of temper and of courtesy to a political opponent, as was exhibited by Lord John Russell in his reply to Lord George Bentinck. We should be glad, for the sake of the utterer, that the speech could be erased from the pages of Hansard, even were we to lose, at the same time, the brilliant and withering reply which it elicited from Mr D’Israeli. A suppression certainly had occurred, whether through mistake or otherwise; and the matter was thought so serious that Earl Grey volunteered an explanation in the Upper House. He had better have let it alone. New charges of suppression were preferred; and finally Earl Grey admitted that, on one occasion at least, he had quoted passages from a Jamaica memorial in support of his argument, totally and purposely omitting to read other sentences, which gave a different construction to the meaning intended to be conveyed! This is popularly said to be the method adopted by a certain personage, who shall be nameless, whenever he has occasion to quote Scripture, and yet it is practised and defended by a high official functionary! We copy the remarks of our contemporary the _Spectator_, as very apposite on this occasion.
