The nitrogen was determined in the products, and equalled 10.5 per cent.
Theory for C_{12}H_{15}O_{6}(NO_{3})_{3} = 9.5 per cent. and for
C_{12}H_{15}O_{6}(NO_{3})_{4} = 11.5 per cent. These nitrates resemble
those of cellulose, and are in all essential points nitrates of ligno-
cellulose.

Mühlhäusen obtained a much lower yield, and probably, as pointed out by
Cross and Bevan, a secondary decomposition took place, and his products,
therefore, probably approximate to the derivatives of cellulose rather
than to those of ligno-cellulose, the more oxidisable, non-cellulose, or
lignone constituents having been decomposed. In fact, he regards his
product as cellulose penta-nitrate (C_{12}H_{16}O_{5}(ONO_{2})_{5}). The
_Chemiker Zeitung_, xxi., p. 163, contains a further paper by Mühlhäusen
on the explosive nitro-jute. After purifying the jute-fibre by boiling it
with a 1 per cent. solution of sodium carbonate, and washing with water,
he treated 1 part of the purified jute with 15 parts of nitro-sulphuric
acid, and obtained the following results with different proportions of
nitric to sulphuric acids:--

Yield Ignition Nitrogen.
per cent. Point.
Experiment I.-- 1. HNO_{3} 1. H_{2}SO_{4} 129.5 170° C. 11.96%
" II. " 2. " 132.2 167° C. 12.15%
" III. " 3. " 135.8 169° C. 11.91%

An experiment made with fine carded jute and the same mixture of acids as
in No. II. gave 145.4 per cent. nitro-jute, which ignited at 192° C., and
contained 12 per cent. nitrogen. This explosive is not at present
manufactured upon the large scale, and Messrs Cross and Bevan are of
opinion that there is no very obvious advantage in the use of lignified
