cor at- .-co 12s COLDEST SPOT OX EARTH. LONDON, Deo. 13 1 have just left laboratories at Leyden. Holland, where the voidest temperature in the world has been attained. Science continues to struggle there against the forces of Nature, and Professor Kmnmerlingh Onnos works unceasingly in the attempt to reach the absolute zero, the state where the thing we call temperature does not exist. To reach the absolute zero it is necessary to go down 273 degrees below freezing point on the Centigrade scale, or over 500 degrees below freezing in the more familiar Fahrenheit thermometer. Yet at these very . low temperatures, at- which even liquid air seems hot stuff, to get down another hundredth of a degree towards the mysterious nothing may represent months or even years of labour.
Asked as to the possibility of Teaching the absolute zero. Professor Onnes said that until and unless some entirely new discoveries are made in the realms of chemistry, it will not probably be possible to get to a lower temperature than 0.), or seven-tenths of a degree absolute.
As far as many chemical reactions are concerned ,the degree of cold that has already been obtained (in the neighbourhood of one degree on the absolute scale) may be regarded as absolute zero.
SELF-STEERED SHIP. LONDON. Dec. 13.
Captain E. T. Britten, of the Cunard liner Laconia, which arrived oil Saturday at Liverpool, after being steered across the Atlantic by the Cyro pilot, an automatic steering device, said the experiment had been a great, success. The Laconia is claimed to be the first British liner to be fitted with the- invention.
The ship made a 75 per cent, better course, added Captain Britten, than anv mar could steer. She had been ■steered to a sixth of a degree. A quarter-master varied a degree on each side of his course. This meant a saving of time on a long voyage, for there was more speed and less roll. The ship would also have less buffeting, which added to the comfort of passengers.
