To Test Iceberg Finder.

New York Times 100 years ago today, September 21, 1912:
British Scientist Coining to Try His Apparatus Off the Banks.
Special Cable to The New York Times.
    LONDON, Sept. 20.— A new method of ascertaining whether there are icebergs near a vessel is to be tested by the inventor, Dr. M. Coplans of Leeds University, who is a passenger aboard the steamship Royal Edward, sailing for Montreal,
    On his arrival in America Dr. Coplans will proceed to the ice zone in a United States cruiser, so it is stated, and there carry out his experiments. The apparatus was designed by Dr. Coplans in association with Mr. French of the electrical department of Leeds University. It is intended to record the variations in the electrical conductivity of sea water, and the theory on which it is based is that the presence of icebergs, however small, sensibly influences this conductivity over a wide area.
    It is asserted that by the use of this apparatus it will be possible also to determine the presence of sewage in drinking water.
