Miss O’Neill repeated her usual characters last week. We saw her in Belvidera, and were disappointed. We do not think she plays it so well as she did last year. We thought her representation of it then as near perfection as possible; and her present acting we think chargeable in many instances, with affectation and extravagance. She goes into the two extremes of speaking so loud as to ‘split the ears of the groundlings’ and so low as not to be heard. She has (or we mistake) been taking a bad lesson of Mr. Kean: in our opinion, the excellences of genius are not communicable. A second-rate actor may learn of a first; but all imitation in the latter must prove a source of error: for the power with which great talent works, can only be regulated by its own suggestions and the force of nature. The bodily energy which Mr. Kean exhibits cannot be transferred to female characters, without making them disgusting instead of impressive. Miss O’Neill during the two last acts of Belvidera, is in a continual convulsion. But the intention of tragedy is to exhibit mental passion and not bodily agony, or the last only as a necessary concomitant of the former. Miss O’Neill clings so long about Jaffier, and with such hysterical violence, before she leaps upon his neck and calls for the fatal blow, that the connection of the action with the sentiment is lost in the pantomime exhibition before us. We are not fastidious; nor do we object to having the painful worked up with the catastrophe to the utmost pitch of human suffering; but we must object to a constant recurrence of such extreme agony, as a convenient common-place or trick to bring down thunders of applause. Miss O’Neill twice, if we remember, seizes her forehead with her clenched fists, making a hissing noise through her teeth, and twice is thrown into a fit of agonized choking. Neither is her face fine enough in itself not to become unpleasant by such extreme and repeated distortion. Miss O’Neill’s freedom from mannerism was her great charm, and we should be sorry to see her fall into it. Mr. C. Kemble’s Jaffier had very considerable effect. Mr. Young’s Pierre is his best character.
