ON SEISMOLOGICAL INVESTIGATIONS. 49 
engaged when in the Isle of Wight was a catalogue of the Shide collec- 
tion of papers bearing upon seismology written in foreign languages. 
Although he continued this compilation while in London, I regret to 
say that the completion of the same has for the time being been inter- 
fered with by ordinary routine work. As illustrative of this latter I may 
take the map which accompanies each report and shows the distribution 
of earthquake centres for the previous twelve months. Inasmuch as the 
production of this sheet involves the consideration and usually a cal- 
culation based upon each of the entries of all co-operating stations, it 
will be understood that much time is spent in the production of what 
is shown as a single plate. Correspondence with stations and those 
interested in our work occasionally occupies a morning. Hach day films 
and other record-receiving surfaces have to be renewed. Films have to 
be developed, measured, and records reduced to a form suitable for publi- 
cation. The registers from all co-operating stations have to be recopied 
and classified. Accurate time has to be kept, and attention has to be 
given to the ordinary meteorological instruments found in most observa- 
tories. Between the hours of 8 a.m. and 10 p.m. we are usually able to 
give information bearing upon our work. My assistants work in the 
morning and again in the evening, and, when occasion requires, also in the 
afternoon. The amount of original work done in the laboratory is out- 
lined in the Reports. 
Registers.—During the past year the registers issued are contained 
in Circulars Nos. 18 and 19. These refer to Shide, Kew, Bidston, Edin- 
burgh, Paisley, Haslemere, San Fernando (Spain), Valetta (Malta), 
Cairo, Beirit, Ponta Delgada, Cape of Good Hope, Calcutta, Bombay, 
Kodikaénal, Irkutsk, Batavia, Trinidad, Lima, Baltimore, Toronto, 
Victoria, B.C., Honolulu, Perth, Sydney, Christchurch, and Mauritius. 
High-speed (24 cm. per hour) record-receiving apparatus has been 
sent to Edinburgh and to Lima. Similar apparatus will be sent to San 
Fernando (Spain). It is expected that the Naturalists’ Society of Cardiff 
will shortly put up a seismograph. 
For a continuation of financial support I again thank the 
Royal Society, the British Association, the administrators of the Gray 
Pund, and Mr. Richard Cooke. I regret to say the support I received 
from the ‘ Daily Mail’ has ceased. The chief expenditure relates to 
Salaries and material. With the latter there is included the cost of 
photographic films required at Bidston. 
The Committee ask for reappointment and a grant of 601.
