“ Wright's portraits are frequently defective in drawing, and without quality or variety of handling, while their flesh tints are often hard. He is seen at his best in his subjects of artificial light, of which the “Orrery” (1766) , the property of the corporation of Derby, and the “Air-pump” (1768) , in the National Gallery, are excellent examples. His “Old Man and Death” (1774) is also a striking and individual production. An exhibition of Wright's works was brought together at Derby in 1883, and twelve of his pictures were shown in the winter exhibition of the Royal Academy in 1886. ”
