April 24. Slight oscillations of unknown origin recorded by 

 both pendulums. 



May 17. Vibrations of moderate intensity; recorded also at 

 Washington and Toronto. The origin is uncertain but has been 

 assigned to Chile where earthquakes were felt at this time. 



May 18. A series of vibrations of moderate intensity travel- 

 ing in an east-west direction. Their origin is unknown. 



June 8. Record of a slight earthquake which occurred in 

 Copiapo', Chile.- 



July 7. The disturbance can be traced to the shock reported 

 from various parts of India. The vibrations began at 4.54 p.m., 

 which, with due allowance for difference in longitude and time of 

 transmission, would correspond to about 3 a.m. at Bombay or be- 

 tween 3 and 4 o'clock a.m. in central India. The movements were 

 of small amplitude and continued for about an hour. As India 

 is on the opposite side of the globe, the movements were probably 

 transmitted across the polar regions as well as in an east-west 

 direction. Stations in Russia, Germany, Spain and Canada also 

 reported the same earthquake. 



July 30. A record showing vibrations of unusual intensity 

 with a maximum amplitude of 24 millimeters. Both pendulums 

 were affected equally and owing to the similarity of this record 

 to other Mexican ones and to the calculated epicentral distance, 

 it is believed that the epicenter was in Mexico or South 'America. 

 The shock was also recorded at Ottawa and its epicenter placed 

 in Mexico. 



July 31. Vibrations very similar to those of July 30, but of 

 much less amplitude. This record probably represents the earth- 

 quake felt in Mexico City. 



August 16. The record of a small earthquake reported near 

 Mexico City. The record which is unusually distinct and regular, 

 shows an amplitude of 20 millimeters and a duration of movement 

 of about 40 minutes. Records were also obtained at the Ottawa, 

 Baltimore and Washington stations. 



August 31. Very small vibrations recorded on both pen- 

 dulums. Possibly represents the vibrations from a slight earth- 

 quake reported in Rome, Italy. 



September 8. A small movement indicated on the seismo- 

 graphs at this station, Ottawa and at Washington. The origin was 

 calculated to have been 4000 miles distant. 



September 22. A vibration of moderate intensity and con-
