upon, some of which are magnified to the enormous size of upwards of
eight feet in length!

Mr. Carpenter's lucernal microscopes are now arranged in a kind of
temple, placed in the middle of a room, and illuminated by the light
of one powerful Argand lamp, so as to be independent of all natural
light; thus, in all seasons, even in cloudy weather, the objects are
as brilliantly displayed as they could be last year when the sun
shone.--_Gill's Repository_.


_Beet Root Sugar._

There are now in France upwards of one hundred manufactories of beet
root sugar, from which were produced last year upwards of 5,000 tons
of sugar, worth 60 _l._ per ton, or 300,000 _l_.; the profit of which
is estimated at 15 _l._ an acre; but, says one of the manufacturers,
the process may be so far improved, that sugar will be made in France
from the beet root at 30 _l._ per ton, which will increase the profit
to 24 _l._ an acre. A writer in the _Quarterly Journal of Agriculture_
observes that "it is difficult to conceive that one half of the sugar
consumed in Great Britain, or in all Europe, will not, in a few years,
be home-made beet root sugar."
