34 RESEARCH COMMITTEES. 
The observatory has been made the base station of the 
British Nationa) Antarctic Expedition, and an agreement 
has been made between the Expedition and Mr. Coleridge 
Farr to run the Eschenhagen variation instruments to be 
installed in the south, and the Kew pattern magnetograph 
at the Christchurch Observatory, at the high speed during 
the whole 24 hours of the arranged seven days. This will 
be commenced on Ist March in Christchurch, and as soon 
as possible in the south, and will be continued as Iong as 
circumstances permit in the souch and in Christchurch until 
the Expedition returns. A notification of the arrange- 
ment, signed by the Commander of the Expedition and by 
Mr. Coleridge Farr, has been sent to all the directors of the 
observatories. 
The work in connection with the observatory and the 
Expedition has caused a temporary cessation of survey 
operations, but these will be recommenced almost imme- 
diately. A report on the work already done has been sent 
to Dr. Glazebrook, and with a request for a renewal of the 
loan of the absolute magnetic instruments used in it. 
REPORT OF COMMITTEE OF AUSTRALASIAN 
ASSOCIATION FOR THE ADVANCEMENT OF 
SCIENCE ON THE QUESTION OF UTILISING 
THE DIAMOND-DRILL BORES OF AUSTRALIA 
FOR THE PURPOSE OF DETERMINING UNDER- 
GROUND TEMPERATURES. 
In view of the information acquired as to the condition of 
the drill bores and the theoretical and practical difficulties 
attendant on the determination of underground tempera- 
tures from such bores, the Committee suggests that no 
further steps be taken by the Association in this matter for 
the present.
