Tue New York correspondent of the Times states 
that Lieuts. Macready and Kelly completed a non- 
stop aeroplane flight across the United States from 
New York to San Diego on May 3. The distance 
traversed was approximately 2600 miles and the time

M. Grorces Barsor crossed and recrossed the 
English Channel on May 6 in a small monoplane 
fitted with a two-cylinder 15 h.p. engine, thus winning 
a prize of 25,000 francs offered by Le Matin for the 
complete journey. M. Barbot left the aerodrome at 
St. Inglevert at 6.20 p.m. and arrived at Lympne at 
7.21 P.M.; the return journey was commenced at

WE learn from La Geographie for February that a 
wireless station has been erected at Mygbugten, on 
the east coast of Greenland, in lat. 73° 30’ N., and 
has been functioning since last October. The station 
is due to the enterprise of the Norwegian Meteoro- 
logical Service. Weather reports are sent by wireless 
telegraphy to the station on Jan Mayen, and thence 
to Christiania. The Greenland station and those on 
Jan Mayen, Iceland, Bear Island, and Spitsbergen 
almost encircle the Greenland sea. 
Ar the Hull meeting of the British Association in

p. 735). Mr. O. J. R. Howarth, secretary of the 
Association, writes to say that though several re- 
ferences have recently appeared to a committee of 
the British Association as having pronounced upon 
the question, no committee was appointed by the 
Association or its anthropological section to investigate 
this subject.
