A tunnel is proposed beneath the
river Humber in England, which
will be 2,840 yards, or nearly two
miles in length. It will begin at
Hesseie, and terminate at Barton in
North Lincolnshire.
A German scientist has found
that, by mixing lamptlack with ten
times its weight Of sulphuric acid

lures to stand tor some hours, and
then washing it free from the acid.
the material acquires the power of
mixing readily with water, and
possesses all the qualities of genuine

A curious and beautiful effect was
lately produced with a block of
manufactured ice in the course of
experiments in Philadel phia. In
the centre of the cake, completely
inclosea by the translucent material,
was bouquet of fresh flowers
Every leaf and blossom was perfect
ly visible, while the brilliancy Of the
solors was enhanced by the refraction
through the ice.
A correspondent Of the Country
Gentleman has discovered that, as a
law If nature, every spotted dog
has the end of his tail white, and
every spotted catthe end of the tail
black. He says he has examined
m ny dogs and cats in France,
England and America, and always
noticed the same result. Our former
Minister to Japan, Mr.. Harris, first
mentioned the fact concerning the
og in letter published some years
since. He has looked at many
paintings of dogs in the galleries of
Paris and elsewhere in regard
to this and found even there the
dogs spotted, always in order, prov
ing to him that the artist had
invariably copied after nature.
The remark of Muspratt that iron
is Natures scavenger has been
justified by recent studies, in which
1t has been shown that strips of
iron thrown into oisterns of water
speedily destroyed all sewage con-
tam'nation. Medlock has proved
by a series of experiments, that iron
produces nitrous acid by its action
on the nitrogenous organic matter,
which is the most destructive power
nature has. He has found as a
general result that by allowing
water to be in contact with large
surface of iron. in about forty-eight
hoursjevery trace oforganic matter was
either destroyed or rendered insluoble
IN which state it could be purified
efectually by filtration.
Recent experiments have shown
very conc.usively that cold-blooded
animals behave like plants with re-
gard to freezing mperatures. Thus
they die at different freezing tenn
perfumes; the honey-bee at 8; the
spider at 3 Q ; the flesh fly survives
a temperature of 60. the silk.worln
egg at one of Il o. And as there
are plants in which the water may
be frozen without their dying, there
are some animals in which this
occures. The silk-worm egg NAV
be frozen solid without extlnguish
ing life In the spider and flies
exposed to freezing temperature, in
the course Of the experiments q part
Of the water was frozen; but as
contraction of the muscles still took
place in a temperature at which
pieces of meat were frozen stiff. it is
improbable that their muscles were
frozen.
Professor Miguel Tina, physician
on duty in the province Of Manila,

that it is not only perfect substitute
