P URE SPRING WA TER.

An interesting account of a spring of water, per-
fectly pure, has reached us; it will be accessible
to our readers, as it seems to be generally, taken
for granted, by all photographers and scientific
men, that all spring water contains both saline
and gaseous impurities, and that rain water, which
is never pure, is the nearest approach to chemically
pure water. The following account shows that
there is at least one spring of which the water is
chemically pure, and will doubtless induce a search
for other springs of a similar nature. The spring
is situated at the head of a small ravine, where a
stratum of fifty or sixty feet of fine gravel
and sand rests upon a stratum of slate rock
of still greater thickness, and which is imper-
vious to water. The water of the spring
filters through the gravel and sand till it
reaches the rock, where it is forced
to take a horizontal direction, and gushes
out from between the two strata in a never-failing
stream, which, after resting for a moment in a
small basin, takes a leap of about five-and-twenty
feet over the perpendicular face of the slate rock
into another basin at the foot of the fall. The
water taken from below the fall is always chemi-
cally pure ; when tested with blue and red litmus
paper, it produces no change in the colour of either.
When mixed with solution of nitrate of silver,not the
slightest change takes place, nor, after standing for
some time, does it deposit any precipitate.
With baryta salts no reaction takes place. A por-
tione• of the water faintly coloured with sulphindi-
otic acid and boiled did not change colour, which

STATISTICS OF PAUPERISM.—The number of per-
sons receiving parish relief in England is often F rapposed to
be larger than it really is. It is less new than it was a year
ago, and it was then but about 4.20 per cent. of t he popula-
tion—that is to say, one in every 24 persons (of m .e n, won' nb:
and children) was a pauper. In the summer th e.nr T 1101"
