amateur naturalist. The stones could almost always be procured near the spot, or their 
places might be supplied by leaden weights. For dredging in lakes and shallow estuaries the 
contrivance seems invaluable, since a large percentage of the delicate plants and animal 
organisms collected by the dredge hitherto in use turn up broken, crushed, and mangled 
out of shape. 
His Excellency the Governor of Zebu was present at a ball given by the British 
Vice-Consul on the 21st. On the 23rd the town celebrated the accession of Don Alfonso 
by a general illumination, and in the afternoon of the 24th H.M.S. “ Challenger left hei 
anchorage and proceeded on her voyage towards the south. After passing Canit Castle 
we spread our sails to a fine northerly breeze. The moon shone brightly upon the distant 
hills of Zebu and Bohol ; while the nearer shore was dotted with the blazing fires of the 
fishermen. During our stay at Zebu, we had received news of a volcano recently formed 
upon the island of Camiguin, situated off the north-west coast of Mindanao; and on the 
morning of the 25th, when the “Challenger” had attained a position between Bohol and 
Siquijor, Camiguin being distant about sixty miles to the eastward, a large volume of smoke 
was seen to rise apparently from the surface of the sea, and at the foot of the high volcanic 
peaks of the latter island. At daybreak on the 26th the new volcano was distinctly visible,

surmounted by a column of smoke or steam drifting to southward with the monsoon. The 
temperature-soundings taken at noon in 185 fathoms, and at a distance of only two miles 
to the north-west of the volcano, afforded no indication of the vicinity of the latter, from 
which we may conclude that the focus of heat in which the lava-streams originate must be 
at a considerable depth below the sea-bottom. The temperature of the water in 185 fathoms 
was found to be i3°-9 C. ; between Bohol and Siquijor, about sixty miles from the volcano, 
and in 375 fathoms, I2°.2 C. ; and at a more northern station in the Philippine inland sea, 
ii° C. from 250 fathoms down to 700 fathoms. The bottom, two miles from the volcano, 
consisted of a greenish mud containing many mineral particles of a coarser texture. When 
the ship had arrived within a short distance of the volcano, we saw before us an irregular 
truncated cone, rising abruptly from the sea to a height of 1950 feet, according to our 
measurements. The surface of the eminence was of a rich dark-brown colour, with large 
patches of light red and grey, forming a striking contrast with the bright green foliage of 
the hills close by. The torn, jagged edge of the crater was only now and then visible 
between the volumes of white smoke which issued both from that orifice and from numerous 
crevices upon the slopes. 
Having landed at the village of Abajo, a collection of huts so much shaken by their 
terrible neighbour as seemingly to be in hourly danger of becoming a heap of ruins, we
