in their nitrogen contents.
It may appear singular that further
contAct with acid and especially sui
phuric acid. will cause the detomposi-
ton OF these cellulose nitrates; yef
such is the case. and therefore. II
is necessary, after nitratiOn, to free
the cellu,bse nitrates rapidly and COM
lp.ctely from the acids present. which
is done by wringing out the MASS in

II is boiled with water which usually
contains a smaH quantity of sodium
carbonate.
AS. however. the cotton fibre is in
the form CT capillary tubes OF consid-
efab,e length. thie washing and
boiling does not suffice to remove the
acid from the interior OF the tubes:
the material is, therefore put into
