be permitted to have some slight under-intrigue of their own.  This, however, requires the exertion of much taste and discrimination; for if we are once seriously and deeply interested in the distress of the play, the intervention of anything like buffoonery may unloosen the hold which the author has gained on the feelings of the audience.  If such subordinate comic characters are of a rank to intermix in the tragic dialogue, their mirth ought to be chastened, till their language bears a relation to that of the higher persons.  For example, nothing can be more absurd than in “Don Sebastian,” and some of Southerne’s tragedies, to hear the comic character answer in prose, and with a would-be witticism, to the solemn, unrelaxed blank verse of his tragic companion.[35] Mercutio is, I think, one of the best instances of such a comic person as may be reasonably and with propriety admitted into tragedy:  from which, however, I do not exclude those lower characters, whose conversation appears absurd if much elevated above their rank.  There is, however, another mode, yet more difficult to be used with address, but much more fortunate in effect when it has been successfully employed.  This is, when the principal personages themselves do not always remain in the buckram of tragedy, but reserve, as in common life, lofty expressions for great occasions, and at other times evince themselves capable of feeling the lighter, as well as the more violent or more deep, affections of the mind.  The shades of comic humour in Hamlet, in Hotspur, and in Falconbridge, are so far from injuring, that they greatly aid the effect of the tragic scenes, in which these same persons take a deep and tragical share.  We grieve with them, when grieved, still more because we have rejoiced with them when they rejoiced; and, on the whole, we acknowledge a deeper frater feeling, as Burns has termed it, in men who are actuated by the usual changes of human temperament, than in those who, contrary to the nature of humanity, are eternally actuated by an unvaried strain of tragic feeling.  But whether the poet diversifies his melancholy scenes by the passing gaiety of subordinate characters; or whether he qualifies the tragic state of his heroes by occasionally assigning lighter tasks to them; or whether he chooses to employ both modes of relieving the weight of misery through live long acts; it is obviously unnecessary that he should distract the attention of his audience, and destroy the regularity of his play, by introducing a comic plot with personages and interest altogether distinct, and intrigue but slightly connected with that of the tragedy.  Dryden himself afterwards acknowledged that though he was fond of the “Spanish Friar,” he could not defend it from the imputation of Gothic and unnatural irregularity; “for mirth and gravity destroy each other, and are no more to be allowed for decent, than a gay widow laughing in a mourning habit."[36]
