Meeting of Chemical Clubs Tonight.

The second joint meeting of the Boylston Chemical Club with the Chemical Society of the Massachusetts Institute of Technology will be held at the Technology Union, this evening at 8 o'clock. Professor A. A. Noyes, of the Institute of Technology, will address the meeting on "The New Process of Photographic Printing, designated 'Catatypy,' invented by Professor Ostwald of Leipsic, Germany." The speaker will describe the method, which is based on a purely chemical process entirely independent of exposure to any kind of light. Prints prepared by the process will be exhibited and illustrative experiments shown.

The meeting will be open only to members of the two clubs.
