638 Further particulars of the Earthquake in Nepal. [Dac. 
strike every one as remarkable, that while here, the shock was more 
violent than elsewhere, its effects should not have been felt equally at 
as great a distance from hence to the north as to the south. Why this ? 
is the natural question, but who can answer where all are in darkness. 
Other explosive forces spread equally in all directions, this did not; 
granting that the centre was where the violence was greatest. To 
the south, the country is a level, uninterrupted plain, calculated to faci- 
litate the rapid transmission of the agitating force, while to the north 
are the mightiest mountains of the world ; it may therefore be supposed, 
that the quantity of force expended in reaching to the summits of the 
Himalayan peaks, and in shaking like molehills the whole of the 
mountain region around, could not be far short in intensity of that 
required to agitate slightly the plains to the southward, even to the 
distance above recorded. In this light, it may be imagined, that the 
explosive force may have spread itself equally on all sides, the greater 
surface distance to which it reached towards the south being balanced 
by the immense vertical spaces it traversed in shaking from their bases 
to their summits the innumerable hills and mountains of the extensive 
region lying between the plains of Hindustan and those of Tibet. 
I subjoin an accurate register of the shocks which have occurred 
up to this date, given me by Captain Roprnson. Many of them have 
been severe, and throughout the whole course of these visitations, 
there have been two distinct varieties observed in the character of the 
shocks: all those at the commencement were of undulatory or swing- 
ing kind ; the others wanted this swell, and were a violent up and 
down shaking, with little lateral, motion. The first may be called the 
horizontal, the latter the vertical, variety. The former alone have been 
destructive to property, while the latter, from the greater noise by 
which they are accompanied, and the more rapid oscillations of the 
ground, are perhaps the more terrifying.
