ON RADIOTELEGRAPHIC INVESTIGATIONS. 73 
tives se rapportant 4 l’émission, & la propagation et 4 la réception des 
ondes électriques. 
‘L’Association Britannique a décidé, de son cété, de recueillir, de 
classer et de commenter les résultats des observations susceptibles de 
faire ressortir les relations entre les phénoménes géophysiques et la 
propagation des ondes électriques. Il entre également dans ses vues de 
dresser la statistique et de faire l'étude des phénoménes anormaux et des 
perturbations atmosphériques. 
‘En conséquence, si les champs d’activité des deux organisations 
viennent 4 avoir des points communs, la Commission Internationale de 
T.S.F.S. engage ses adhérents 4 préter éventuellement-le concours le 
plus complet 4 la ‘‘ British Association.’’ ’ 
At a meeting of the British Association Committee on May 8, 1914, 
the following resolution was adopted :— 
‘That the Radiotelegraphic Investigation Committee of the British 
Association for the Advancement of Science take cognisance of the 
resolution adopted by the Commission Internationale de Télégraphie sans 
Fils Scientifique at the recent conference in Brussels, and desire to 
affirm that they. find themselves in full accord with the definitions, as 
expressed in the resolution, of the differences between the aims and 
methods of the researches promoted by the two organisations; while, 
in regard to those researches in which the two bodies both take an 
active interest, this Committee warmly welcome and value highly the 
offer of co-operation, and gladly undertake to give all assistance in 
their power.’ 
The Committee has expended up to the present in office expenses, 
printing, and distribution of forms, the sum of 1441, 
[Note.—The following communication was circulated to Members of the Com- 
mittee by the Secretary on behalf of the Chairman in December, 1914 :— 
The war has naturally had a very direct effect on radiotelegraphic investi- 
gations. About August 1 last, private wireless telegraph stations throughout 
the Empire were nearly all dismantled or taken possession of by military authori- 
ties, while naval and other Government stations stopped all merely scientific 
observing. The radiotelegraphic stations in Russia, Germany, and neighbouring 
countries doubtless discontinued the filling up of our forms as soon as mobilisa- 
tion began. A few stations in India, Australia, Canada, the West Indies, and 
the United States are, however, still at work. In the last-named country about 
thirty stations are making observations. 
The Committee’s programme for the collection of statistics three days a week 
in all parts of the English-speaking world and in a few other countries was 
planned to embrace one complete round of the seasons. The fact that the pro- 
gramme has been interrupted after only three months of really full work 
diminishes greatly the scientific value of such statistics as have been collected. 
Tt also implies considerable financial loss. A large batch of forms was distri- 
buted to our Navy in July: in clearing for action these forms would probably 
be wasted. The German edition was distributed in June. The Russian edition 
also was probably distributed before the outbreak of war. 
The extensive scheme of special observations projected for the occasion of 
the solar eclipse failed almost completely in the countries in which the eclipse 
‘was visible. A small amount of work was done in Norway and Sweden. All 
the necessary forms had been printed, and some had been circulated before the 
war started. The financial loss to the Committee in this respect exceeds a 
hundred pounds.
