An enterprfsing Frenchman has in

as to be conveniently carried in the vest
pocket, can be fired ten times without
9eloading, and with greater ease and GER

he whole length of the weapon is four
inches, which can be reduced 90 two and
ave-elghths by unscrewing the barrel.
A new alimentary substance, the seeds
0f the Bolivian cotton tree, has attracted
the attention of the Academic dcs Sci
enccs. Il is rich in nitrogenlzed sub
stances, and contains twenty-three per
cent. Of fibrine and six OF casein. M.
SAGE thought that -four from the seed
would be very suitable for pastry and
sweets. IL ID likely to be used in sugar
making IS substitute for carbonic acid.
A variety of prehistoric objects in honr,
such as amulets, cups, knives, daggers,
rings, buttons, bracelets, ETC., have been
Aound in u stratum, existing at depth
of about five feet in the mud Of Lake
Neuenburg. Switzerland. The finder,
Herr G.. Kaiser, believes them to be older
than the stone aud bronze implements of
the same locality, and he proposes to call
the period to which they belong "tha
age Of horn. y
The great sand dunes along the banks
oi many rivers, and particularly along
the shores at the southern end of Lake
Michigan, are due to the presence Of the
Ammophilia Arenaria, or sand gathering
grass, which possesses q remarkable
power of drawing up moisture, Indeed,
II may almost be called miniature water
pamp, for it is able to keep the earth wet
Tor several inches around it. This wet
earth catches and holds the drifting sand.
The process goes on, the grass growing
and the sand collecting, until q great
sand dune is the result.
A curiosity in the way OF watches was
shown by Mr.. E. Sordes, director of the
watch-makers' school at Geneva, before
the Theological Section of the Society of
Arts. This wonder is nothing less than
a watch with one wheel, manufactured
il Paris in the last century by NJ.
Gautrin. The watch was presented to
the National Institute in 1900, being
then ia deplorable state; but the
teacher Of the repairing section of the
Nchool, M. Emile James, has, after many
hours Of labor, succeeded in 70 establish
ing harmony between the various organs,
90 that now it is in good order. The
great wheel which gives the watch its
name occupies the bottom of the case
and the centre Of the plate. In has sixty
teeth, and is thirty-three nm. in diane
ter It's axis carries two pinions, one of
which receives the motive force from a
barrel, and the other carries the minute
work. The function of this great wheel
IL Quadruple. First, it acts on lift,
then on lever operating on an another
destined to lower the AXIS Of the watch,
and lastly on q third lever, tho latter
serving to return power to the great
wheel at the moment when the action
relents by the rise OF the axis.
