GERMAN EXPERIMENTS. '[:. (diTSWGttArn-rp.Bss jssocutiok—corrmon-r.) (Rec. June 6,. 1 p.m.) Berlin, June 6. An airship is manoeuvring over Berlin and making important efchergraph experiments. FEAR OF INFLAMMABILITY. The possibility of communication b'v means of wireless telegraphy between balloons and the earth has lrequently been mooted, and fears have been, expressed that thei. sparks caused by tho,signals might give rise to danger in the presence of the inflammable/gases used for. the inflation of the balloons. Professor Hergesell claims, however,' to , have shown, by means of a ' series of - experiments carried out at sea, when radidtelegraphio messages were transmitted, between the vessel:on which ho was sailing and small balloons fitted up with receiving apparatus,, that no danger was caused by theso signals.' Ho was able, even at.distances of 10 miles, >o cause apparatus, for operating valves, in the balloons to be sot in action by means, of wireless telcgraphv. In 'the case of the voya»e in BoMum of the Condor balloon, equipped with .radiotcloerapluc apparatus, communication was t'stablished between the balloon- and the signal staJj on f°, r .inreless telegraphy on the -summit of the Palais de Justice of Brussels,- and ■ messes were also received from the Eiffel-Tower "in Paris by the occupants of the balloon.7
