USING WIRELESS TO CORRECT THE TIME.

' FRENCH <fc AMERICAN EXPERIMENTS. ■ Wireless telegraphy has enabled the French and American authorities to determine within the one-hundredth part of a second tho difference in time between Paris and Washington, but experiments are still in progress for the purpose of eliminating all errors. The French Government sent a commission to Washington to renew jointly with the American officers at Arlington the exchango of wireless signals with the Eiffel Tower. It is composed of Martial Simonin, an astronomer of the Observatory of Paris: Captain A, Carrier, of file Colonial Infantry, and Xa.rai Lieutenant Gignon. '.Profasw Henri Abraham, of tho Sorbonne. sailed later to join the party, with tho object of studying with photographic registration wireless signals and experiments in the velocity in the propagation of wireless waves. Later the first party was tc- return to Paris, and bo replaced by Eloi Vienurt, an astronomer of tho Observatory of Paris, and P. Anverny, an ensign of the u.ivy. n J ho have been working in the Eiffel Tower. The American Navy "Dopr.nm.ent at the samo timo will send an astronomer from the Naval Observatory in Washington and one or more_officers.;' with the same objects, to Pans. Tho officers of both navies will 'thus work first on one side and then on the other, so as to eliminaie as far as possible the errors arising from the personal equation. The astronomical instruments used in the observations will also be employed first on one sidy and then mi the other to correct such slight variations as may be due to mcchar.ical imperfection."
