Abstract
LONGITUDE BY WIRELESS.—The scheme for linking up the observatories of the world by utilising wireless time-signals was referred to in NATURE for May 20 last (vol. cv., p. 370). It must be understood that no appreciable increase of accuracy over the older method by cable signalling is claimed; indeed, where the observers are not interchanged the precision is less. But the gain in convenience, expense, and wide distribution of signals is considerable, and it is known that where the travelling-wire method of observing transits is adopted, personality is greatly reduced; what remains is of the same order as the small local deflections of gravity, which can be eliminated only by extensive geodetical operations.
