PHYSICS OF THE GLOBE. 103 



of Canada, New York, and New England. It appears to 

 have been most severe in the Adirondack and Green Moun- 

 tain regions, where the vibration was sufficient to do some 

 slight damage. From this centre the tremors were felt 

 through the valley of the Ottawa and the St. Lawrence, from 

 Lake Ontario to Three Rivers, through Central New York as 

 far west as Geneva, and southeastward through New Eng- 

 land to the sea-coast. The direction of the shock was from 

 west to east {Monthly Weather Review, November, 1877; 

 American Journal of Science and Arts, III., xv., p. 21 ; Ca- 

 nadian Naturalist, vol. viii., No. 6). 



On November 15, 1877, about 11 45 A.M., Omaha time, 

 several shocks of earthquake were felt throughout the whole 

 of Iowa and Nebraska, extending also into Kansas and Mis- 

 souri on the south, and into Dakota and Minnesota on the 

 north, the reports coming mostly from points on the Union 

 Pacific Railroad. About 2 45 A.M. of the next day, a shock 

 from west to east was felt in Tennessee and North Carolina 

 {Monthly Weather Review, November, 1877 ; American Jour- 

 nal of Science and Arts, III., xv., p. 21). 



On January 23, 1878, at 7 55 P.M., a severe earthquake 

 was felt at Iquique, Peru, the influence of which extended 

 to Arica, and other places along the coast and in the inte- 

 rior. It did some slight damage, but was not so destructive 

 as the one of May 9, 1877, not being attended by any tidal 

 wave. 



A few days later, however, on January 27, the harbor of 

 Callao was visited by a destructive tidal wave, which did 

 much damage to the sea-wall and inundated the railroad 

 station. The disturbance appeared to come from the north, 

 and did not entirely subside for several days. 



Nearly simultaneous with these disturbances in South 

 America, a series of shocks were felt in Western Europe. On 

 January 27, shocks were reported from Upper Styria, and 

 about noon on January 28, several shocks were experienced 

 in Southern England and Northern France, being most severe 

 in the Channel Islands. 



On February 27, 1878, at 5 P.M., shocks of earthquake 

 were felt at Reykjavik and other places in the southwestern 

 part of Iceland ; and at 8 P.M. an eruption of flames and lava 

 began on the northern side of Mt. Hekla. On subsequent
