Bickerstaff’s plays and comic operas are continually acted: they come under the class of mediocrity, generally speaking. Their popularity seems to be chiefly owing to the unaffected ease and want of pretension with which they are written, with a certain humorous _naïveté_ in the lower characters, and an exquisite adaptation of the music to the songs. His Love in a Village is one of the most delightful comic operas on the stage. It is truly pastoral; and the sense of music hovers over the very scene like the breath of morning. In his alteration of the Tartuffe he has spoiled the Hypocrite, but he has added Maw-worm. Mrs. Cowley’s comedy of the Belles’ Stratagem, Who’s the Dupe, and others, are of the second or third class: they are rather _refaccimentos_ of the characters, incidents, and materials of former writers, got up with considerable liveliness and ingenuity, than original compositions, with marked qualities of their own. Goldsmith’s Good-natured Man is inferior to She Stoops to Conquer; and even this last play, with all its shifting vivacity, is rather a sportive and whimsical effusion of the author’s fancy, a delightful and delicately managed caricature, than a genuine comedy. Murphy’s plays of All in the Wrong and Know Your Own Mind, are admirably written; with sense, spirit, and conception of character: but without any great effect of the humorous, or that truth of feeling which distinguishes the boundary between the absurdities of natural character and the gratuitous fictions of the poet’s pen. The heroes of these two plays, Millamour and Sir Benjamin Constant, are too ridiculous in their caprices to be tolerated, except in farce; and yet their follies are so flimsy, so motiveless, and fine-spun, as not to be intelligible, or to have any effect in their only proper sphere. Both his principal pieces are said to have suffered by their similarity, first, to Colman’s Jealous Wife, and next to the School for Scandal, though in both cases he had the undoubted priority. It is hard that the fate of plagiarism should attend upon originality: yet it is clear that the elements of the School for Scandal are not sparingly scattered in Murphy’s comedy of Know your own Mind, which appeared before the latter play, only to be eclipsed by it. This brings me to speak of Sheridan.
