where otherwise mentioned. | 
General. 
THERE is no modification to report in the general situation at Oxford. The tenant 
of the house purchased by Dr. Crombie’s benefaction shows no disposition to move ; 
but the work has been carried on in the ‘ Students’ Observatory’ without serious 
difficulty. 
The salary for Mr. J. S. Hughes, provided for the first year entirely by the generosity 
of Dr. Crombie, has for the second year been provided half by Dr. Crombie and half 
by the Board of Scientific and Industrial Research. Mr. Hughes has taken over the 
work of determining epicentres and times, under the general supervision of Professor 
Turner, and by this welcome addition to our resources arrears are being steadily 
reduced, as mentioned below. 
International. 
Seismology has sustained further severe losses by the deaths of Dr. Otto Klotz of 
Ottawa and Professor Omori of Tokyo. Our deep sympathies are extended to Japan, 
not only for this personal loss, but on account of the terrible calamity which befell 
Tokyo and Yokohama in the devastating earthquake of September 1. 
There is to be a meeting of the International Union for Geodesy and Geophysics 
in Madrid in October next. Professor H. H. Turner and Mr. J. J. Shaw have been 
in nominated by our National Committee as delegates for Seismology. 
Instrumental. 
Nothing has yet been heard of the seismograph taken to Christmas Island by the 
Eclipse observers in 1922. Writing under date June 4, Mr. H. 8. Jones, now H.M. 
Astronomer at the Cape, promises to write again to Christmas Island on the 
subject. 
Mr. J. J. Shaw has despatched two of his seismographs to Entebbe in Uganda, and 
one to Fordham University, New York. These were independently purchased, but 
are mentioned to show the expanding distribution of machines of the type approved by 
the Committee. 
Another instrument has been prepared by him for exhibition at Wembley, whither 
some maps showing the distribution of epicentres and of observing stations, and a 
set of the publications, are also being sent. 
The performance of the Milne-Shaw seismograph has, moreover, been tested by 
Professor Rothé on the experimental table at Strasbourg with very satisfactory results. 
The curve representing the motion of the table is almost identical with that shown by 
the seismograph.
