So with Lord Lytton’s Helen Mainwaring, the sunny gladness of whose nature must have vent like a bird’s, though he forbids us to fancy that that gladness speaks the levity which comes from the absence of thought: “it is rather from the depth of thought that it springs, as from the depth of a sea comes its music.” Well and wisely Molière’s Cléonte exclaims, “Veux-tu de ces enjouements épanouis, de ces joies toujours ouvertes? et vois tu rien de plus impertinent que des femmes qui rient à tout propos?” Such a _femme_ as the same author’s Zerbinette, a self-convicted giggler in and out of season, yet whose confession may be twisted into an example the other way, when she says, “J’ai l’humeur enjouée, et sans cesse je ris: mais, tout en riant, je suis sérieuse sur de certains chapitres.” Among the writings of M. de St. Evremond there is an essay on the Idea of a Woman that never was, nor ever will be found. Emilia he calls this all too perfect, impossible she. And amongst the foremost of Emilia’s fine qualities he reckons the co-existence of seriousness _au fond_ with vivacity of mien. “For we find that the gayest humour doth, at length, become tiresome; ... the most effervescent liveliness either disgusts or wearies you.” In the case of the celebrated Duchesse de Longueville, De Retz notices the exquisite effect of the sudden bursts of gaiety which would at times dispel her habitual but not inexpressive languor. Mdlle. de Scudéry, in her “Clélie,” was painting a well-known, perhaps too well-known, contemporary in the person of Clarice, when, “parmi toute cette disposition qu’elle a pour la joie,” she ascribes to this charmer, _qui rit si aisément_, a facile faculty of tear-shedding: _elle sait pleurer_, whenever occasion justifies weeping. As Lady Eastlake says, in her little treatise on Music, a change of key is the most powerful engine in the hands of a musician: we cannot bear the monotony of one key long, even the most joyful: “Gaiety without eclipse wearieth me, May Lilian.” We long for “a mournful muse, soft pity to infuse.” The Hon. Miss Byron takes the liberty of telling the sister of Sir Charles Grandison that “Your brother has hinted, Charlotte, that he loves you for your vivacity, and should still more, if you consulted time and occasion.” The affections are justly said to be more readily called into play by a mixture of mirth and melancholy; ours being a twofold life, the union of mortal with immortal, we covet happiness, yet turn back anon to the more majestic form of sorrow. There is a form of cheerfulness which, we are assured, nobody can stand:— “Send me hence a thousand miles From a face that always smiles;”
