 occasion to indicate the work done in these directions, 

 a summary may be given here, with reference to the 

 sections whose interests were specially concerned.' 

 [Referring first to subjects associated with Section A, 

 Mathematics and Physics], ' the Prime Minister of 

 the Commonwealth (Mr. Cook) received a deputa- 

 tion of astronomers and physicists on the projected 

 solar observatory on Mount Stromlo, and accorded 

 them a favourable hearing. In Sydney the local 

 branch of the British Astronomical Association 

 requested, through the president, Dr. Roseby, a 

 visit from the astronomers, some of whom attended 

 and addressed the meeting. The Sydney branch of 

 the Mathematical Association also invited some 

 mathematicians to address them. The different 

 State observatories (Perth, Adelaide, Melbourne, and

 astronomers, and as a result of friendly discussion 

 of problems and difficulties, invited by the directors 

 of the observatories, several memoranda were drawn

' The geologists of the party in Western Australia 

 . . . visited the Irwin River to examine the Permo- 

 Carboniferous glacial beds, marine beds and coal 

 measures, the Darling Ranges to see the crush- 

 conglomerates of pre-Cambrian age, the Stirling 

 Ranges with their highly contorted quartzites of 

 unknown age, and finally the goldfields of Kalgoorlie 

 and Coolgardie. At the time of the Adelaide meeting 

 a party of geologists and chemists visited Port Pirie 

 and Broken Hill for the purpose of seeing the 

 occurrence of the ores and the methods of working
