174 REPORT—1899, 
5. Spain: Cadiz. San Fernando. Instituto y Observatorio de Marina. 
Director, Commodore J. VINIEGRA. 
When first installed the instrument at this station showed but few 
movements of the ground, and these were slight. On April 27, 1899, it 
was therefore dismounted, but set up again on the same day ; the position 
of the balance weight being slightly altered and a more perfect equilibrium 
of the boom assured. Its “period i is 16 seconds. Now it appears to work 
better, but the vibrations are not very intense as compared with those 
from other localities. This lack of sensitiveness may, Commodore 
Viniégra remarks, be due to the foundations, in which there are several 
‘stone furrows,’ surrounded with mud.
