cases infiltrates from tlie sea is by no means unlikely, but in others, where the 
volcanoes are two or three miles from the coast or any creek, it would appear not 
improbable that the water is derived from surface percolation. Saltnes.s is a very 
common characteristic of mud volcanoes, as is indeed indicated by the term saZse^ 
often used for them. 
Although the emissions from the volcanoes in their ordinary condition are 
„ , of the aboA'e described insignificant character, at

uncertain (and sometimes long) intervals, emptions 
of a much more violent character take place. A t such times mud and stone.s 
are shot out with great force and noise, accompanied by largo quantitio.s of 
inflammable gas, which in many cases catches fire and gives rise to a volume 
of flame that lights up the country for miles around. Of course such eruptions 
vary in intensity, some being much more violent than others. I was not fortu¬ 
nate enough to see anything of the kind, but there are several records of 
their oceurrence. 
From one of the Kyauk Pbyu volcanoes, Dr. McClelland states, that “ vapour 
and flame were seen by the inhabitants of Kyauk Phyu to issue to the height of 
several hundred feet above the summit during the principal shock of the earth¬ 
quake of the 26th August 1833^.” This was a violent earthquake felt, amongst 
other places, at Calcutta, Agra, Nepal, and Lassa. 
On the 23rd of March 1839 a A^ery sei^ere earthquake was felt throughout 
the whole of Burma, during which “ fires, mingled with smoke and ashes, rose 
to a fearful height ” from one of the same group of vents.® 
Mr. HoAve, Marine Assistant at Kyauk Phyu, thus describes an eruption 
which occurred on the 6th of February 1843;—“ We had, last night, a most magni¬ 
ficent volcanic eruption. The mountain, which is of moderate lieight, and shaped 
somewhat like a pyramid, is about three or four miles from the station, which was 
rendered as light as noon-day, though midnight at the time. The eruption 
commenced at about 11 p. M., unaccompanied by any rumbling, but throwing up 
masses and particles of lava (.sic ; vide p. 202) to an immense height, and presenting 
a most magnificent spectacle, visible all round the country. The weather had 
been for some evenings previous close and threatening, though the glass kept 
Up, varying from 30° 12' to 29° 98' for the last five or six days. 
“ The fire gradually went out, and all was still again by about half an hour 
after midnight. 
“ This eruption takes place, from what 1 hear, generally once in two years, 
sometimes annually.”'' Subsequently—how long does not appear—Mr. Howe 
wrote,—“ The volcano is still in a bubbling boiling state, the orifice not larger than 
a tea cup, and there is a hot slimy fluid to be dipped up at the surface, but no 
vapour or noise is emitted, and it is otherwise quiet.”^ As no vapour was emitted
