OF THE AUSTRALIAN MEETING. 715 
astronomers and physicists on this project, and accorded them a favour- 
able hearing. In Sydney the local branch of the British Astronomical 
Association requested, through the President, Dr. Roseby, a visit from 
the Astronomers ; and the Astronomer Royal, Professors E. W. Brown, 
Eddington, Nicholson and Turner and Mr. C. G. Abbot attended and 
addressed the meeting. The Sydney branch of the Mathematical Asso- 
ciation also invited some visiting mathematicians to address them ; 
Professors Perry and Turner responded to Professor Carslaw’s invita- 
tion. The different State observatories (Perth, Adelaide, Melbourne 
and Sydney) and Mr. Tebbutt’s private observatory at Windsor, 
N.S.W., were all visited by several astronomers, and as a result of 
friendly discussion of problems and difficulties, invited by the directors 
of the observatories, several memoranda were drawn up by the visitors. 
The geologists of the party in Western Australia, under the local 
guidance “of Professor W oolnough, visited the Irwin River to examine 
the Permo-Carboniferous clacial 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 un- 
known 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 occur- 
rence of the ores and the methods of working and smelting. Another 
party at the same time visited the Sturt River to see the Cambrian 
elacial beds, and explored the Permo-Carboniferous glacial beds and tle 
archeeocyathine limestones of Hallett’s Cove, and ‘finally the granitic 
rocks in the neighbourhood of Victor Harbour. From Melbourne the 
geologists went to Macedon to examine the alkaline igneous rocks and 
to Bacchus Marsh for the Permo-Carboniferous glacial tillites lying 
upon striated surfaces of older rocks. 
From Sydney there were excursions of both geological and biological 
interest to the Blue Mountains, which afforded the geologists an oppor- 
tunity of studying the leading features of the geological structure of 
New South Wales and the remarkable elevation which this, in common 
with many other parts of the Continent, experienced in late Tertiary 
or post-Tertiary times. An examination was also made of the Jenolan 
Caves, which are typical examples of stalactitic cayes in limestone of 
Silurian age, one of the interesting features of which was the remains 
of an aboriginal skeleton embedded in the stalagmitic floor. The excur- 
sion to West Maitland and Newcastle gave an opportunity of examining 
the productive coal measures of the State. 
At Brisbane two of the most notable excursions arranged for 
geologists were those to the Glass House Mountains, a series of 
trachytic voleanic necks rising abruptly from the plain, and to Ipswich 
to examine the Trias-Jura coal measures and associated volcanic rocks. 
Some of the most noteworthy points that impressed the geologists 
from Europe were the remarkable extent on the Australian Continent of 
Permo-Carboniferous glaciation, the evidence of comparatively recent 
extensive elevation, the well-preserved plains of erosion at different 
geological horizons, and the evidences of glaciation as early as the 
Cambrian epoch.
