SEISMOLOGICAL INVESTIGATIONS 225 
the International Seismological Summary and is in the same form as that 
for the years 1918 to 1924, which was due to Prof. Turner, and appeared 
with the Report for 1928. 
In these catalogues the earthquakes are in chronological order. It is 
hoped that it will also be possible to publish a continuation of Turner’s 
Index Catalogue of Epicentres 1913°0-1920°5, in which a geographical 
arrangement is adopted. This is in course of preparation. 
Seismographs.—A second Milne-Shaw seismograph has been supplied 
by Mr. J. J. Shaw to the Liverpool Observatory and Tidal Institute at 
Bidston, in order to give the two horizontal components of tilting of the 
red sandstone of Bidston Hill with the rise and fall of the tide in the Mersey 
estuary. These investigations are being conducted by Prof. Proudman 
and Dr. Doodson in their research on tidal phenomena. 
A working seismograph has been constructed by Mr. Shaw and erected 
on the second floor of the Science Museum, South Kensington. ‘The 
pendulum (370 lbs.) is supported on the main outer wall of the building 
and records upon smoked paper in order that the public may see the seismo- 
graph in operation. The record travels 8 mm. per minute and runs for 
two days. The instrument is also fitted with a bell-ringing device such that 
an earthquake will give alarm, but slow tilting of the building, due to tem- 
perature, etc., produces no effect. 
A Milne-Shaw seismograph is on order and nearing completion for 
Brisbane. Prof. Alexander Brown reports that the two seismographs 
provided by the Committee on loan to the University of Cape Town are 
functioning satisfactorily. 
British Earthquakes—A small earthquake occurred near Inverness on 
August 16, 1934, at 2.15. The shock was felt over the Highlands and was 
recorded by the seismographs at the English stations, including the Wood- 
Anderson at Kew. 
_ Other small disturbances which may have been due to such causes as 
the collapse of old workings in mines were reported in the newspapers on 
the following dates : 
Llanhilleth, Monmouth . } . March 2, 1935 
Aspley, Nottingham ‘ i - May 3, 1935 
Jersey . ; d p : - July 28, 1935 
The Quetta Earthquake.—Last year we were reminded by the devastation 
on the borders of Bihar and Nepal how liable India is to great earthquakes. 
This year we have to mourn the loss of some 15,000 lives in an earthquake 
f almost equal severity at Quetta, on May 31, 1935. Only a few months 
arlier, Mr. W. D. West, of the Geological Survey of India, in his report on 
o earthquakes which occurred in 1931, had written: ‘ At present the 
ajority of buildings in Quetta are about as unsoundly built from an 
arthquake proof point of view as it is possible for them to be.’ It is 
satisfactory to note that the need for special regulations governing building 
‘in the areas liable to earthquakes is appreciated by the local authorities in 
India. The desirability of the provision of more seismological stations 
‘With suitable equipment is emphasised in the latest annual report of the 
Geological Survey of India, and we should like to lend all possible support 
to this plea. 
_ Montserrat.—A series of small earthquakes in the West Indian island, 
Montserrat, has caused material damage and considerable alarm, the dis- 
turbances being associated with the emission of large quantities of sul- 
phuretted hydrogen and other gases from vents near to Plymouth, the only
