DIORAMA OF NINEVEH. .
Mr. Frederick C. Cooper, the artist sent out by the British Museum to aid the researches of Dr. Layard, has opened, at No 3 Grosvenor Street, a diorama of the scenes of his proceedings. Opening with the city of Mosul, the view passes along the banks of the Tigris to the exea- rations at Nimroud and Kouyunjick, and M. Botta!s discoveries :at Khorsabad ; and closes with the interior of Dr. Layard's Assyrian home, on the occasion of an entertainment given by him to the neighboitring chiefs. Mr. Cooper, who greatly heightens the interest 'of the exhibit sin by himself delivering the lecture, commenced by observing that the die= rama is dependent for its attractiveness less on the intrinsic beauty of the scenes than on their historic and traditional a.sseciations. The painting'fii not so vivid or diversified in its effects as that of some similar spectacles ; but it possesses a more than common air of fidelity and truthful arrange- ment. For the widely-felt interest of the subject? as Well as the warrant of authenticity it possesses, this diorama should be one of the best attended of the season.
