determines the quantity of the water that should be drunk. It is
generally believed, however, that the therapeutic action of a certain
quantity of mineral is most effective when it is administered in a
relatively large quantity of water.
7. Hot waters produce more notable effects than cold waters.
In regard to the temperature of waters used for bathing, it is
known that a temperature as low as 66° F. reduces the bodily tem-
perature about 2° within 10 or 15 minutes, reduces the frequency
of the pulse, and produces a flow of blood to the brain, lungs, kidneys,
and other internal organs; but after a cold bath of short duration a
reaction takes place that causes the blood to return to the skin and
the pulse becomes normal or even slightly quickened. Water 88°
to 95° in temperature is considered to be indifferent in its effect on
the body temperature, but baths at this temperature are considered
of value in the treatment of nervous debility and sleeplessness. Hot
baths accelerate the circulation, induce a flow of blood to the surface,
and increase the quantity of blood in the superficial blood vessels,
thereby causing congestions and profuse sweating. Such baths are
beneficial in the treatment of partial paralysis and of rheumatic
troubles. The high temperature is probably the main element of
value in mud and sand baths, though the weight of the material may
help somewhat.

ANALYSES OF CALIFORNIA SPRING WATERS.

SOURCES OP ANALYSES.
Most of the chemical analyses that are given in this report are
taken from a book by Anderson,1 who made analyses of most of the
important springs of the State in 1888-89. A few earlier analyses
that were made by Oscar Loew in connection with the Wheeler Sur-
vey 2 are available. A number of others have been taken from the
reports of the California State Mining Bureau, and others have been
obtained from advertising folders and from private files. A few
analyses were made by Mr. F. M. Eaton, at Oakland, Cal., for use in
this report.
The source of each analysis is given in the tables, so that the hypo-
thetical forms may be consulted by those who wish. The following
abbreviations have been used to indicate the principal references,
