ON SEISMOLOGICAL INVESTIGATIONS. 57 
If we omit the stations lying within 60 degrees of the origin, 
the above two averages respectively become 1°5 and 2°0. 
The average distance from the origin of the eastern stations is 
88 degrees, whilst that of the western stations is 90 degrees—two 
distances which are practically equal. 
The inference is that motion is transmitted more freely towards 
the West than it is towards the East. 
District No. 2.—North of India, or approximately 80° E. and 
40° N. 
The earthquakes considered are Nos. 832, 886, 982, 1070, 1293, 
and 1468. 
The number of records obtained at 9 stations lying to the North of 
this district was 46; the average per station was therefore 5.1. 
At 8 stations lying to the South of this district 29 records were 
obtained, the average per station therefore being 3°6. 
If we only consider stations more than 60 degrees distant from 
the origin, these two averages respectively become 5°2 and 3°8. Here, 
again, we are led to the conclusion that motion was propagated more 
freely towards the North than in the opposite direction. 
It must, however, be pointed out that the average distance of these 
southern stations from the origins was somewhat greater than that 
of the northern stations, these distances being respectively 65 and 
85 degrees. 
To the East of long. 80° E. 33 records were obtained at 9 stations, 
or 3°6 records per station. To the West of this meridian 38 records 
were obtained at 9 stations, or on the average 4°2 records per station. 
It would seem, therefore, that in this district, as in District No. 1, 
motion was propagated more freely towards the West. 
The average distances from the origin of these Hast and West 
stations are respectively 76 and 75 degrees. 
District No. 3.—East Coast of Japan, or approximately 140° BK. 
40° N. 
The earthquakes considered are Nos. 884, 1031, 1266, 1427, and 
1510. 
Nine stations with northerly bearings recorded 28 disturbances, 
or on the average 3°1 per station. 
Eight stations with southerly bearings noted 20 disturbances, or 
on the average 2°5 per station. 
If we only consider stations more than 60 degrees distant from 
this district these averages become 3:0 and 2°6. 
The average distance from the origin for the southerly stations is, 
however, somewhat greater than for the northerly stations, these 
distances respectively being 91 and 77 degrees. 
Five stations lying to the East of 150° BE. long. gave 13 records, 
or an average of 2°6 per station. 
Eleven stations lying to the West of this same region yielded 34 
records, or on an average 3°1 per station. Here again we observe 
motion has been propagated more freely towards the West. 
District No. 4.—North and North-East of New Guinea, or approxi- 
mately 150° BE. and 0° N, or S.
