WILLAMSON PICTURES ARE POSTPONED UNTIL FRIDAY

On account of the hockey game with Yale the presentation of the Williamson undersea pictures, scheduled for tomorrow night at the Union has been changed to Friday evening at 8 o'clock. The films, entitled "Beauty and Tragedy of the Deep", have been previously exhibited at Symphony Hall, Boston, and portray the animal and vegetable life of the deep sea bottom, with both still and moving pictures.

The ingenious device for taking these pictures, invented by Mr. Williamson when he was a cartoonist for a Norfolk paper, consists of a long tube with observation windows at one end extending to the bottom of the sea from the hold of a specially built ship. Light to overcome the submarine darkness, is furnished by a battery of powerful lights that are let down near the observation box. The Scientific American has acclaimed Mr. Williamson's achievement in originating submarine photography, the creation of a new art.
