DIR. Cutter states that the increase
OF diseases, deeaying teeth,
premature badness and general lack OF
muscular and bone strength are greatly
due to the impoverished quality Of
Hour now in use, the glaten being
thrown away IN order TO make the lour
white. He urges the use of unbolted
hour, and Of eggs, milk and butter.
He denies that fish is brain food, or
that Agassiz ever said That it was, and
claims that butter, being nearly all fat,
is a better kind Of brain food than any
other.
Those in pursuit OF the marvellous

An Italian professor has made some
very agreeable researches, resulting in
the discovery that vegetable perfumes
exercise n positively healthful influence
on the atmosphere, converting its oxy-
gen into ozone, and thus increasing its
oxidizing influence. lie recommends

Efforts 10 reduce monkeys to discip-

however, trained several of them TO

Some of the German and Russian rail
mills employ, it is stated, m ingenious
method of overcoming the difficulty of
cutting hot rails, so that they may be
all Of the same length when cold. Ac-
cording to this plan, the rails are
looked at through a dark glass; when
they have cooled TO q certain tempera-
ture, they cannot be perceived; and if,
therefore, n dark blue or an orange
yellow glass is used, the rails may still
lie at y red glow but the light radiated
from them does not reach the ego. 1t
may he considered that the light from
two rails, observed through the same
dark glass, disappears at the same tenn
perature, and thus u rule is obtained
for cutting the rails to the same perfect
and identical guage. This plan has
| been in use for n considerable time
| with excellent results.
During the course of some
tions at Villagrande, Sardinia, some
very remarkable instruments have been
found, if, as is believed, they belong to
the bronze epoch, which is supposed TO
have been exceptionally prolonged in
this part of the island. The instru-
ments in question are two bronze saws
and a four-pronged fork, all found in
the same repository.

Pouring oil on troubled waters" is
an old phrase, and there are many au-
| thentic instances of the value Of oil in
preventing the breaking of the waves
over n vessel at sea. Some experiments
with oil on waves were lately made in
England. Bottles filed with oil were
sunk 10 the bottom of the harbor OF
| Peterhead, in which the sea was break
ing heavily. The oil was then released,
and, rising to the surface, it exercised
an immediate and magical effect in
soothing the troubled waters. The sea
became quite smooth and glossy-look-
ing, and there was n visible softening
down of the waves, which, in place OF
being sharp-crested, were turned into
long undulating seas. The experiments
were so successful that the proposal to
lay oil upon the mouths of harbors by
means of pipes was discussed as n not
very remote project.
DIR. Henry Barnes records a case OF
an extremely severe attack OF govt
brought on by sleeping in n newly
painted room. Three years before, the
patient, an old man, had suffered from
n slight attack of the disease, but soon
recovered, and up to the time OF this ex-
posture, had been quite free from equity
symptoms. The introduction of lead
into the system is given rs the cause oil
the attack.
