ON SEISMOLOGICAL INVESTIGATIONS. 31 



our Colonies and with individuals and institutions in Great Britain, with 

 the object of obtaining exhibits. Mr. M. H. Gray sent a large map of 

 the world, 30 feet by 15 feet, which shows stations co-operating with 

 the British Association and the centres of marked seismic activity. I 

 sent a tidal-load recording instrument made in Newport, and through 

 Mr. E. W. Munro, a British Association type of seismograph. The 

 Bev. Father W. O'Leary forwarded a model of a new type of seismo- 

 graph which he is using at the Mungret College, Limerick. In the 

 Machinery Hall, Mr. J. J. Shaw, of West Brornwich, erected a pair of 

 horizontal pendulums which, notwithstanding the varying loads and 

 vibrations to which they are subjected, have recorded several large 

 earthquakes. These with other instruments, enlargements of seismo- 

 grams and various pictures, constitute the chief features amongst the 

 exhibits. I mention this matter because it is the first exhibition of its 

 kind in this country, and also because it has done very much to call 

 attention to a new science. 



New Stations. — Mr. W. Davis, Director of the Meteorological Office, 

 Argentina, is establishing at least three new stations at which the 

 British Association type of instrument will be used. Another instru- 

 ment is to be established at the University of Cork, and one at Cardiff 

 is now in working order. The instruments despatched last year to 

 Cape Verde, Ascension, Fernando Noronha, and St. Helena have 

 been installed and records are being obtained from these places. Those 

 sent to the Seychelles, Cocos, and Fiji have arrived at these places 

 and we may shortly expect to receive records from the same. I may 

 here mention that the instrument at Fernando Noronha, like the one at 

 San Fernando in Spain, was purchased for our benefit by Mr. Eobert 

 K. Gray. The instrument purchased by the Pacific Cable Company 

 to be used at Fanning has not yet reached that island. The reason for 

 (he delay is that an officer from that' island has not been in England to 

 receive instructions, and it is seldom that the island is visited. 



The Colonial Office have kindly sent out circulars to Governors and 

 other officers in Colonies bordering the Eastern and Western sides of 

 the Atlantic inviting them to co-operate in the seismological work of 

 the British Association. These include Newfoundland, Bermuda, Bar- 

 bados, Jamaica, and Turks Island; other islands in the West Indies, 

 Guiana, Honduras, the Falklands and the Gold Coast. Mr. Joseph 

 Rippon of the West India Cable Company has given great assistance 

 towards the furtherance of this object. 



On March 28, 1911, the Legislative Council of Bermuda passed a 

 Seismographic Act ' enabling the Board of Public Works to purchase 

 and maintain a seismograph. 



On behalf of the International Seismological Association I have sent 

 out to stations co-operating with the British Association a circular 

 which states that the Central International Bureau at Strasburg is 

 prepared to test earthquake instruments . These tests will be made 

 free of cost for stations in countries which have joined the International 

 Association, but for others there will be a charge of from 100 to 150 

 marks. An enclosure with this circular asks for material to complete 

 a macroseismic catalogue for 1907.
