Thiers was the only child of this woman, although his father had other children by a former marriage, one of whom keeps a restaurant in Paris. * * * * * The some time expected death of THOMAS MOORE occurred on the 26th of February, at Sloperton Cottage, near Devizes. Like Southey and Scott, the British Anacreon had for several years before his decease, quite lost his intelligence, and he lingered in seclusion, and in half slumbering unconsciousness, personally well nigh forgotten by the world. His history is little more than a history of his writings. He was deservedly popular in society, for his amiable qualities, and fascinating manners; he shared the intimacy of the greatest men and greatest writers of his age, more prolific of eminent characters than any other since that of Shakspeare, Raleigh, and Sidney; and dividing his time between the quiet charms of domestic ease, and the smiles of the most elevated classes, he may be said to have been a fortunate and happy man. As a song writer, he was doubtless unrivalled. His versification is exquisitely finished, harmonious, and musically toned. The sense is never obviously sacrificed to the sound; on the contrary, he delighted in that species of antithetical and epigramatic turn, which is generally held to excuse some roughness, and to be scarcely compatible with perfect melody of rhythm. In grace, both of thought and diction, in easy, fluent wit, in melody, in brilliancy of fancy, in warmth (but scarcely depth) of sentiment, and even in purity and simplicity, when he chose to be pure and simple, no one has been superior to Moore; but in grandeur of conception, power of thought, and above all, unity of purpose, and a high aim, he was singularly deficient, and these are necessary to the character, not of a sweet minstrel, but of a great poet.
