in (1), but the conditions varied by passing a
stream of carbonic acid gas through the solution contained in a flask,
until Cl compounds ceased to be given off. The analysis of the purified
oxycellulose gave C 43.53, H 6.13.

(3) The conditions were as in (2), but a much stronger hypochlorite
solution--viz. 12 deg.B.--was employed. The yield of oxycellulose
precipitated from solution in soda lye (10 p.ct. NaOH) was 45 p.ct.
There was only a slight residue of unattacked cellulose. The analytical
numbers obtained were:

Oxycellulose C 43.31 43.74 43.69
" H 6.47 6.42 6.51

B. _Oxidation by permanganate_ (KMnO_{4}). (1) The cellulose 16 grms.
was treated with 1100 c.c. of a 1 p.ct. solution of KMnO_{4} in
successive portions. The MnO_{2} was removed from time to time by
digesting the product with a dilute sulphuric acid (10 p.ct.
H_{2}SO_{4}). The oxycellulose was purified as before, yield 40 p.ct.
Analytical numbers:

Oxycellulose C 42.12 42.9

(2) The cellulose (16 grms.) was digested 14 days with 2500 c.c. of 1
p.ct. KMnO_{4} solution. The purified oxycellulose was identical in all
respects with the above: yield 40 p.ct. C 42.66, H 6.19.

(3) The cellulose (16 grms.) was heated in the water-bath with 1600 c.c.
of 15 p.ct. H_{2}SO_{4} to which were added 18 grms. KMnO_{4}. The yield
and composition of the oxycellulose was identical with the above. It
appears from these results that the oxidation with hypochlorites acids 1
atom of O to 4-6 of the unit groups C_{6}H_{10}O_{5}; and the oxidation
with permanganate 2 atoms O per 4-6 units of C_{6}H_{10}O_{5}. The
molecular proportion of N in the phenylhydrazine residue combining is
fractional, representing 1 atom O, i.e. 1 CO group reacting per 4
C_{36}H_{60}O_{31} and 6 C_{24}H_{49}O_{21} respectively, assuming the
reaction to be a hydrazone reaction.

Further investigations of the oxycelluloses by treatment with (a)
sodium amalgam, (b) bromine (water), and (c) dilute nitric acid at
110 deg., led to no positive results.

By treatment with alcoholic soda (NaOH) the products were resolved into
a soluble an
