The 'Great Walpolian Battle' and the attacks on Bute and other favourite ministers were very fertile in the pamphlet, but already there were certain signs of alteration in its character. Pulteney and Walpole's other adversaries had already glimmerings of the newspaper proper, that is to say, of the continual dropping fire rather than the single heavy broadside; to adopt a better metaphor still, of a regimental and professional soldiery rather than of single volunteer champions. The _Letters of Junius_, which for some time past have been gradually dropping from their former somewhat undue pride of place (gained and kept as much by the factitious mystery of their origin as by anything else) to a station more justly warranted, are no doubt themselves pamphlets of a kind; but they are separated from pamphlets proper not less by their contents than by their form and continuity. The real difference is this, that the pamphlet, though often if not always personal enough, should always and generally does affect at least to discuss a general question of principle or policy, whereas Junius is always personal first, and very generally last also. On the other hand, Burke, whether his productions be called Speeches or Letters, Thoughts or Reflections, is always a pamphleteer in heart and soul, in form and matter. If the resemblance of his pamphlets to speeches gives the force and fire, it is certain that the resemblance of his speeches to pamphlets accounts for that 'dinner-bell' effect of his which has puzzled some people and shocked others. Burke always argued the point, if he only argued one side of it, and it is the special as it is the saving grace of the pamphlet that it must, or at least should, be an argument, and not merely an invective or an innuendo, a sermon or a lampoon.
