If this latter is square, or even elliptical, it is
found that, beyond an angle of 15 degrees, there are differences of 4 or
5 degrees in the indications given with the same intensity of current by
the same needle, according to the latter's intensity of magnetism. This
inconvenience is quite grave, for it often happens that a needle changes
magnetic intensity, either under the influence of too strong currents
sent into the apparatus, or of other magnets in its vicinity, or as
a consequence of the bad quality of the steel, etc. It was therefore
urgently required that this should be remedied, and from this point
of view the new mode of winding the wire is an important improvement
introduced into medical galvanometers.--_La Lumiere Electrique_.

THE SUSPENSION OF LIFE.
Every one knows that life exists in a latent state in the seeds of
plants, and may be preserved therein, so to speak, indefinitely. In
1853, Ridolfi deposited in the Egyptian Museum of Florence a sheaf of
wheat that he had obtained from seeds found in a mummy case dating back
about 3,000 years. This aptitude of revivification is found to a high
degree in animalcules of low order.
