ound that eels are
irrecoverably deprived of life when a shock is sent through their
whole body; but when only a part of the body is included in the
circuit, the destruction of irritability is confined to that
individual part, while the rest retains the power of motion. Different
persons are affected in very different degrees by electricity,
according to their peculiar constitutional susceptibility. Dr. Young
remarks, that a very minute tremor, communicated to the most elastic
parts of the body, in particular the chest, produces an agitation of
the nerves, which is not wholly unlike the effect of a weak
electricity.
The bodies of animals killed by electricity, rapidly undergo
putrefaction, and the action of electricity upon the flesh of animals
is also found to accelerate this process in a remarkable degree.
The same effect has been observed in the bodies of persons destroyed
by lightning. It is also a well-established fact, that the blood does
not coagulate after death from this cause.
_Transplanting Shrubs in full Growth_.
Dig a narrow trench round the plant, leaving its roots in the middle
in an isolated ball of earth; fill the trench with plaster of Paris,
which will become hard in a few minutes, and form a case to the ball
and plant, which may be lifted and removed any where at
pleasure.--_French Paper_.
_Freezing Mixture_.
A cheap and powerful freezing mixture may be made by pulverizing
Glauber's salts finely, and placing it level at the bottom of a glass
vessel. Equal parts of sal ammoniac and nitre are then to be finely
powdered, and mixed together, and subsequently added to the Glauber's
salts, stirring the powders well together; after which adding water
sufficient to dissolve the salts, a degree of cold will be produced,
frequently below Zero of Fahrenheit. But Mr. Walker states, that
nitrate of ammonia, phosphate of soda, and diluted nitric acid, will
on the instant produce a reduction of temperature amounting to 80
degrees. It is desirable to reduce the temperature of the substances
previously, if convenient, by placing the vessels in water, with nitre
powder thrown in occasionally.
_Microscopic Examination of the Blood_.
By the aid of Tulley's achromatic microscope, and under highly
magnifying powers, it has recently been discovered that the globules
of the blood congeal into flat circular bodies, and arrange themselves
in rows, one body being placed partly underneath another, a
