NEW SEARCHLIGHT
PIERCES DENSE FOGS A GREAT DISCOVERY Fog may become merely an unpleasant incident instead of a terror to sailors, airmen, and travellers, if Mr. J. L. Baird’s “noctovision” apparatus fulfils its promise. In a laboratory Mr. Baird interposed a dense cloud of ammonium chloride between a ventriloquist dummy and a group of spectators. The doll’s features were clear, though the fog nearly choked Mr. Baird’s assistants. The “invisible searchlight,” which has 16 times the power of a beam of ordinary light through smoke, vas commended by Admiral Mark Kerr who declared: “It is the biggest thing that has been discovered for sea and air for a long time.”
