Lantern Slide Exhibition.

Professor Moore gave the fourth of his series of exhibitions of lantern-slides in the Fogg Museum last evening. Several views of the cathedrals at Chatres, Amiens, and Rheims were shown and their peculiarities described. One damaging alteration in the Gothic architecture during the 14th century, said Processor Moore, was the introduction of private chapels into the cathedrals. The original outer walls with their rich stained-glass windows were destroyed and other walls erected which included the buttresses within the building.
