his island that are now filled with water; for instance, in the
neighborhood of San Pablo there are said to be eight or nine.

[The hot springs.] The hot springs of Los Banos are numerous, and in
their vicinity large quantities of steam are seen to issue from the
shore of the lake. There are about a dozen which give out a copious
supply of water. The principal one has been enclosed, and made
to flow through a stone aqueduct, which discharges a considerable
stream. The temperature of the water as it leaves the aqueduct is
178 deg.. The villagers use it for cooking and washing; the signs of the
former employment are evident enough from the quantities of feathers
from the poultry that have been scalded and plucked preparatory to
cooking. The baths are formed by a small circular building six feet
in diameter, erected over the point of discharge for the purpose of
securing a steam-bath; the temperature of these is 160 deg. and 140 deg.. A
change of temperature is said to have occurred in the latter.

The rocks in the vicinity are all tufa, and some of the springs break
out close to the cold water of the lake. Near the aqueduct, a stone
wall surrounds one of the principal outlets. Two-thirds of the area
thus enclosed is occupied by a pond of warm water, and the other third
is divided into two stone reservoirs, built for baths. These baths
had at one time a high reputation, and were a very fashionable resort
for the society of Manila; but their celebrity gradually diminished,
and the whole premises have gone out of repair, and are fast falling
to ruin.

The water of the springs has no perceptible taste, and only a very
faint smell of sulphur is perceived. No gas escapes from it, but a
white incrustation covers the stones over which the water flows.

Some of these waters were obtained, and since our return were put into
the hands of Dr. C. T. Jackson, of Boston, who gives the following
analysis:

Specific gravity, 1.0043; thermometer 60 deg.; barometer 30.05 in.

A quantity of the water, equal in bulk to three thousand grains of
distilled water, on evaporation gave--

Dry salts, 5.95 grains.

A quantity of the water, equal in bulk to one thousand grains of
distilled water, was operated on for each of the following ingredients:

Chlorine 0.66
Carbonic acid 0.16
Sulphuric acid 0.03
Soda and sodium 0.97
Magnesia 0.09
Lime 0.07
