A POPULAR FALLACY.-The notion
that ice puri6es itself by the process Of
freezing is not based upon trustworthy
observation. On the contrary, it is ut
terly wrong in principle to take ice for
consumption from any pond the water
of which is so foul as to be unfit for
drinking purposes.
How TO PRODUCE HEAT.-The ami
NAL body makes its own heat, and is so
far independent that, If it can be pro-
tected from the cooling or heating influ-
ences of the outer world. it will MAIN
tain an equal and healthful tempera-
ture. The source of heat is food, which
in the subtle processes Of the organism
and life acts as fuel and undergoes oxi-
dalton and combustion" In the ab-
sence of sufficient or suitable food, or
what is the same thing in effect-when,
from any cause, the normal functions of
digestion and assimilation are impaired,
the body is not properly heated from
within, and the subject feels cold.
DANGERS OF MoLDY BREAD.-A sim
gular case of poisoning from eating q
pudding made in part Of moldy bread is
reported in the Sanitary Record. The
main facts of the case may be briefly
stated as follows: The principal mate
rails of the pudding consisted Of scraps
of bread left from making toast and
sandwiches, and they had been about
three weeks accommodating. To these
scraps were added milk, eggs, sugar,
currants, and nutmeg. The whole was
baked in very slow oven, and was
subsequently eaten by the cook, the
proprietor of the eating. house in which
it was prepared, the children of the pro-
prietor, and two other persons. All of
these became violently ill, with symp-
toms of irritant poisoning. One Of the
children Jagged three years) and one of
the adults died. The necropsy of the
body of the child caused the medical
men to suspect poisoning, and accord
ingly the viscera, together with the rem
nant of the pudding, the materials used
in making it, the matter vomited, ETC.,
were sent TO chemical analyst, Mr..
Alfre1 Allen, for examination. He
made tests for several poisons, but with
out positive result. A puppy was fed
with the pudding for two days
without any poisonous effect. He
was then led to look for ergot
in the pudding, and was soon startled
to find unquestionable evidence of its
presence, as far a. the chemical reac-
tons went, though he was unable, with
the aid OF the microscope, to detect any
actual ergot. From these facts Mr.. Al
len infers that the reactions hitherto sup
posed to be peculiar to ergot are COM
mon to other poisonous fungi.-PopulGr

THE VOLTAIC PENCIL.-There is at the
present time scarcely q single branch of
industry torwhich electricity is not lend.
ing its aid. Art, however, has thus far
received but little benefit from this
source, if we except the application of
electricity to electro-metallurgy. We
are pleased to learn, then, that an inn
portant discovery has Just been made at
Paris by NJ. Belief, whose invention
consists of q voltaic pencil, by the use
of which designers and dranghtsmen
will be enabled to dispense entirely with
the aid of the engrsver. The editors of
