of the visiting Members, and did not afford opportunity for any large 
proportion of the local Members to take part in them. Recognising 
this generous attitude on the part of the local organisers and Members, 
the General Secretaries of the Association addressed a circular letter 
to Members of the Overseas Party in Adelaide, inviting them to take 
advantage to the utmost of the official excursion arrangements. 
A general all-day excursion took place to Angaston and district. 
Luncheon was provided by Mr. Charles Angas in the Agricultural Hall 
at Angaston. Mr. Glynn, Commonwealth Minister of External Affairs, 
proposed the toast of the visitors, and Sir Oliver Lodge replied. Sir 
H. R. Reichel proposed the health of Mr. and Mrs. Angas. Motor- 
cars were provided by residents to convey Members on short drives 
in the neighbourhood. A limited party visited the vineyards and 
cellars of Messrs. Seppelt, at Seppeltsfield, and lunched there. On 
the return journey the Chateau Tanunda Company’s wine-cellars at 
Tanunda were inspected, and tea was provided by the Company. A 
botanical excursion by motor to the hills near Adelaide was conducted 
by Professor T. G. B. Osborn; and Professor E. C. Stirling led an 
anthropological excursion to Milang, Lake Alexandrina, where a party 
of aborigines was seen. Mr. W. Howchin conducted a geological ex- 
cursion, lasting over August 10 and 11, by motor to the Sturt River, 
Hallett’s Cove, Inman Valley, and Sellicks’ Hill, the party spending 
the night at Victor Harbour.

President, delivered a discourse on ‘The Ether of Space.’ His Excel- 
lency the Governor, Sir H. Galway, K.C.M.G., presided. The 
lecturer described the properties of the ether of space as the omni-

spite of its intangible and generally insensible character. He dis- 
cussed the relation between ether and matter, and urged that the 
experimental elusiveness of the ether was a natural consequence of 
its uniformity and of the universality of its functions. A vote of 
thanks to the lecturer was proposed by Professor E. C. Stirling, 
C.M.G., F.R.S., and seconded by Professor T. W. Edgeworth David, 
C.M.G., F.RB.S.

at a number of private houses in the Mount Lofty district.

Commonwealth Club. Sir J. Downer was in the chair, and speeches

Professor W. J. Sollas, F.R.S., on ‘‘ Ancient Hunters,’’ Sir Oliver 
Lodge presiding. The lecturer emphasised the results of recent re-

remains of the human race, and discussed the correlation of the
