Milne Horizontal Pendulums, and the Committee recom- 
mends that the General Council of this Association may be 
induced to approach the Governments of these States with a 
view to securing the early installation and maintenance of 
this kind of instruments at their respective observatories. 
Records of seismic disturbances occurred in the various 
States during the last two years, and are shown in the fol- 
lowing separate reports : — 
Queensland and Tasmania.—No returns. 
South Australia.—Extract from letter of Sir Charles 
Todd, Government Astronomer, and list of recorded earth- 
quakes, appended. 
New South Wales——The Government Astronomer, Mr. H. 
C. Russeli, states that no records of earthquakes were re- 
ported to him; none felt ac the Sydney Observatory. 
Western  Australia.—Letter from the Government 
Astronomer, with list of earth-tremors recorded by the Milne 
Horizontal Pendulum, appended. 
Victoria.—Laist of earthquakes appended. 
New Zealand.—Special Reports by the joint Secretary, 
Mr. G. Hogben, appended.

ArreErR preliminary testing for the necessary instrumental 
adjustments, the Milne Seismograph No. 20, im charge of 
Mr. George Hogben, M.A., Wellington, has been in regular 
working since Ist October, 1900, and it has afforded many 
records of an interesting character. Many of these records 
are evidently identical with records of seismic disturbances 
in various parts of the world, as shown by instruments of 
the same type, or by the Rebeur-Ehlert instruments at 
Strassburg and Hamburg, or by other seismographs whose 
records are referred to in the monthly circular issued by the 
Kaiserlichen Haupt Station fur Erdbebenforschung, at 
Strassburg. The most notable of the comcidences are those 
relating to the following :— 
(1) E.Q. of 8.10.’00, No. 4 on Strassburg list, October, 
1900, which began at 8., 36 mins. later than at 
Wellington; amplitude 25 mm. at S., 22 mm. 
(period of pendulum 163 secs.) at W.
