When the apparatus above described
is in full working order, from 2 to 3 lb. of sodium carbonate may be
converted into sodium sulphite in less than half an hour, or several
gallons of water saturated. I have also on connecting the apparatus with
a powerful refrigerator obtained in a short time a large quantity of
liquid SO2. It will be found advantageous, however, during the
preparation of sulphurous anhydride, to employ a layer of water covering
the bottom of the vessel to about 1 inch in depth. Carbonic anhydride
and phosphoric anhydride may also be readily obtained in any desired
quantity by slight alteration; but in case of phosphorus the air must be
allowed to enter only gently, since a rapid current would at all times
determine the fracture of the vessel.--_Chem. News_.

THE ARRANGEMENT OF ATOMS IN SPACE IN ORGANIC MOLECULES.[1]
[Footnote 1: Ueber die raumliche Anordnung der Atome in
organischen Molekulen, and ihre Bestimmung in

The expression "chemical structure," as commonly used by chemists, has,
as is well known, nothing to do with the arrangement of atoms in space.
