The election and qualification of Messrs. C. M. Hall, F. B.

Mr. D. B. Wainwright read a paper by invitation on Longi¬ 
tude by wireless telegraphy. He described the experiments 
made in October, 1901, with the Marconi apparatus, at Nan¬ 
tucket, and on the lightship, 48 miles off. Signals from the ship 
were recorded on the chronograph sheet along with the usual 
clock-beats, and means were found to eliminate the instrumental 
errors. [Not published.] 
In the discussion that followed Mr. Bauer spoke of attempts 
to determine longitude by noting the times of simultaneous mag¬ 
netic disturbances. Mr. HxVYFORD pointed out that the new 
wireless method, even if it could not be used over more than 50 
miles, was probably more precise than any other except the tele¬ 
graphic. The paper was further discussed by Messrs. Farqu- 
har, Paul, Winston, Marvin, and Gore.
