Mr. LANG'S No. 44 is a very large likeness of a very comely lady, but the work will hardly live long in the spectator's memory. Mr. ROSSITER takes the field boldly with "The Ideals, Types of Moral, Intellectual, and Physical Beauty." Except for the brilliance of color, and a certain sentiment, by which the light proceeds from the moral type, we do not much admire the picture. The difficulty with the spectator will be, we are sure, that he recalls within his own circle of friends types more beautiful for each ideal. Mr. Rossiter's portraits of his brother artists, Messrs. DARLEY and DUGGAN, are admirable likenesses, each somewhat mellowed in expression by the artist. The sharp intellectual precision of Mr. Duggan's countenance, and the bright nervous sensibility of Mr. Darley's, are both somewhat subdued upon the canvas. What we candidly say of these pictures we say boldly, because we recognize and appreciate the fine feeling which animates the artist. Mr. GRAY'S No. 54, "King Death," attracts much attention. But is it the "Jolly Old Fellow," or the "King of Terrors," or the "easeful death" of which the poet was enamored? There is something fine in the picture--a strain of Egyptian placidity permeates the features. And such colossal placidity is full of fate. There is a latitude allowed the artist in these themes. Yet we do not feel satisfied, much as we like the picture. Mr. ROTHERMEL'S No. 5, "Murray's Defence of Toleration," is a very pleasant picture of the Düsseldorf style. We like one thing in this work, and that is its preservation of the balance of history, by showing that the Catholics were not always the persecutors. The contrast of the religious repose of the rear with the jangling fanaticism of the foreground is in harmony with the differing qualities of light. It is a thoughtful and beautiful picture, Mr. FREEMAN'S 359, "Study for an Angel's Head," has a Titianesque fascination, and the earnest regard of the faces is extremely lovely. It is none the less charming that it has a mortal loveliness--if we might say so without treason to the immortality of all beauty. We have no doubt, in our own critical mind, that any beautiful woman would make a beautiful angel. Mr. MOUNT'S No. 118, "Who'll turn Grindstone?" is one of his characteristic Yankee incidents. It is very true and genuine in feeling, but the picture is too white and streaked. No. 344 is a natural and spirited portrait of the poet Stoddard by Mr. PRATT.
