That letter, apart from its historical value, is important at the present moment, inasmuch as we think that no one can peruse it without feeling convinced that, in any struggle for power, the Whigs would have no scruple in sacrificing principle to their interest. They have done so already repeatedly, and their tactics have always been to retain or recover office by making large concessions to the demands of the Radical or the Irish party. We are not without apprehension that they are, even now, contemplating some move of a similar nature, to be made during the ensuing session of Parliament, for the purpose of retrieving some portion of their lost popularity. The Radical party have openly threatened to withdraw their support from the ministry unless some increase of the suffrage shall be granted; and an agitation to that effect would be particularly palatable to the free-traders, as it might tend, in some degree, to draw public attention from the utter failure of their schemes. Any movement, in such a direction, would be followed by the most disastrous consequences. A further infusion of the popular element into the House of Commons, would simply lead to greater encroachments on the constitution, more reckless experiments upon the stability of our trade and commerce, and more culpable bidding by ministries for popularity in every shape. Where is to be the end of such an agitation--unless, indeed, we were to follow the notable examples of France and Germany, and adopt universal suffrage--if, on each occasion when the country is suffering under the pressure of noxious laws, no mode of relief can be suggested, save through an extension of the Reform Bill? We should have thought that the success of the first experiment was not quite so conspicuous as to invite another of the same nature. The impudence of the Radical faction is really almost incredible. Mr Cobden and his confederates have got free trade, from the effects of which we are presently languishing; and they now propose to revive our spirits and replenish our purses by stocking the House of Commons with an additional importation of men of precisely the same caste and opinions as their own! We suspect that the funds would scarce be lively if the country were assured that forty Brights, instead of one, were seated in our National Assembly.
