pp. 280 and 281, Neither is it in accord with observations made at inctcorologiial stations in Foimosa, 

 which were as follow : Taito, 7 12-0; Tainan, 7 4-2; Koshun, 7 6-7; Taichu, 7 2 '8; and Taihoku, 73-0. 

 At the two latter places, which are in Northern Formosa, the motion was slight, whilst at the three former 

 places, in the southern part of the island, the movement was strong, houses were shaken, and at Koshiui 

 clocks were stopped. At Tainan there was vertical movement. The inference is that the origin was the 

 S. of that city and its time would be at least 2 minutes earlier than that recorded in Tainan. 



From the times of arrival of maximum motion at Manila, Tokyo, and Irkutsk, an origin is arrived at a 

 point about midway between the northern end of Luzon and the southern extremity of Formosa, or 

 approximately at 120° E. Long, and 21° N. Lat. The values M -C for these three stations also indicate 

 an origin in this district. 



From the times taken for largo waves to travel from such an origin to the above three places it would 

 appear that the time at the origin would lie between 7h. 2m. and 7h. 4m. As the former of these is more 

 nearly in accord with observations made in Formosa and at other stations than the latter, it is the one 

 adopted and used in the construction of the following table : —
