Among the subjects discussed at the recent Inter- 

 national Navigation Congress at Westminster on July 

 2-6 were the latest improvements in regard to signalling 

 at sea and on the coast. Fourteen reports were sub- 

 mitted to the Congress, covering the current practice 

 in Great Britain, Belgium, France, Holland, Italy, 

 Japan, Russia, Spain, Sweden, and the United States. 

 Reference was made to experiments carried out by 

 Trinity House, in 192 1, in connexion with synchronous 

 signalling, in which two types of sound-transmitters 

 were used — one a standard submarine bell, and the 

 other a Fessenden oscillator, in conjunction with a 

 wireless transmitter. The signals received from these 

 were of such a character as to enable the distance to 

 be calculated of objects invisible in fog, but within 

 submarine sound range. A wireless installation, 

 lately erected at Inchkeith in Scotland, was mentioned 

 as affording facilities for experimenting with direction 

 messages to vessels equipped with a simple type of 

 receiver gear. The most important advance in light-
