_ -- The purpose of these investigations is the closer characterisation of the products known as 'oxycellulose' and

In the presence of air, oxidation of the cellulose to oxycellulose rapidly occurs resulting in greatly weakened fibers.

The products were oxycelluloses, with a cupric reduction equal to that of an oxycellulose directly prepared by the action of HClO_ {3}.

The oxycellulose, after purification, dried at 110°, gave the following analytical numbers:

With regard to the properties of the denitrated products they fix all basic colours without mordant and may be regarded as oxycellulose therefore.

The author has studied this reaction quantitatively for the esters both of cellulose and oxycellulose, at two stages of 'nitration,' represented by 8. 2-8.6 p.ct. and 13. 5-13.9 p.ct. total nitrogen in the ester-products, respectively.

The oxycellulose was precipitated from the filtered solution: yield 45 p. ct.

Two specimens of oxycellulose were prepared by treating cotton wool with hydrochloric acid and potassium chlorate (A), and with sulphuric acid and potassium dichromate (B), and

It is probable that the presence of this oxycellulose has a marked influence upon the behavior of cotton, especially with dye matters.

From these and some other substances, the following percentage yields of furfuraldehyde were obtained: Hydrocellulose, 0.854; oxycellulose, 2.113; reduced cellulose,
