to cause buildings to oscillate, the period of convulsion being at the last
place about three minutes.” Captain Baird Smith, summing up the
data of this earthquake says, “ The extreme limit of the earthquake
of 1819 appears to have been Poona, where its force was only being
feebly experienced. The tract affected therefore extends, so far as
existing information shows, from about the meridian of 69° to that of
74° E. Long, and from ] 8° to 24° N. Lat ” These limits are, however,
by no means well ascertained, especially to the Westward of Cutch,
and also to the Northward. The limits of the earthquake of the
29th April last, defined under such data as I have obtained, would
appear to show the area of convulsion to be between the same meridians
of longitude as that of 1819, but differing in parallels of latitude, that
of April having extended to Mount Aboo, or about 40 miles further
North, but again not reaching so far South by about 120 miles.
The difference therefore in the two earthquakes amounts to the
following :—First, that while equal in the area of convulsion and
situated between the same meridians East and West, the earthquake
of 1819, starting from 18° North, extended northwards 360 miles*
while that of April last, starting from 20° North, extended northwards
280 miles. Thus, while the data of the earthquake of 1819 gave an
approximate area of convulsion of 99,000 square miles, that received
for the earthquake of 1864 gives an area of 77,000 square miles, or
22,000 square miles less of convulsed area than the calamitous one
which happened 45 years ago.
There is also another great difference—Thus, while the area of the
earthquake of this year is great, by the providence of God the e\i!
effects have been relatively very small, for excepting the loss of 20
lives at Limree, by the falling of dilapidated buildings, no tidings of
injurious consequences have been received.
The particulars of the earthquake of this year have come from the
following positions :— Mount A.boo, the extreme North point, to Belee-
mora, the point farthest South, intermediately between which we have
Ahmedabad, Kaira, and Surat, and to the West Dholka, Cholera,
Limree, Wudwan, Dlmndooka, and Wagur. The times of shoe an
the period of continuance I regret to say are so vaiied as to be a most
useless for the purpose of calculation. The following is an extiaet
