“ As an artist, Mr Allan possessed much facility of invention; with a keen discernment of those evanescent circumstances in the outward form, which mark the different shades of passion and affection in the mind. With the talent of artfully arranging the various parts of a crowded and bustling scene,—such as appears in some of his comic productions, he possessed that feeling for simplicity, which gives to his graver compositions, a classical and antique air of elegance. ”
