=NITRO-DENSITE.=--A coal-mine explosive made by Kynoch, Ltd. It was of the Carbonite type, and was at one time on the Permitted List--

Date of Permit 1-9-13 Nitroglycerine 18 Barium nitrate 25 Wood meal 5·5 Starch 28·5 French chalk 23

Limit charge 28 oz. Power (swing of ballistic pendulum) 1·47”

=*NITROKOL.=--A gelatinised nitrocellulose powder intended for use in rifles. It consists of a nitrocellulose, mostly soluble in ether-alcohol, and gelatinised with that solvent. It is made up in the form of small square flakes which are graphited.

=NITROLIT.=--A high explosive used by the Germans for filling shell. It is a mixture of ammonium nitrate and trinitro-anisol.

The name was formerly given by C. Lamm of Stockholm to a blasting explosive containing blasting gelatine, ammonium nitrate and other substances.

=NITRO LOW-FLAME, NOS. 1= and =2= are American coal-mine explosives on the Permissible List. They are nitroglycerine mixtures.

=NOBEL AMMONIA POWDER.=--A coal-mine explosive which was on the old Permitted List--

Ammonium nitrate 84 Nitroglycerine 8 Wood meal 8

=NOBEL GELATINE DYNAMITE.=}

=NOBEL GELIGNITE.=} Under these names explosives were introduced during the War with modified compositions, the potassium nitrate being replaced by sodium nitrate, and the percentage of nitroglycerine being reduced.

=NOBELIT= is a German blasting explosive containing blasting gelatine, carbonaceous substances, inorganic nitrates and sodium or potassium chloride.

=AMMON-NOBELIT= contains ammonium nitrate, and the proportion of blasting gelatine is limited to 4 per cent. It may contain sodium or potassium oxalate, and various other substances that are not present in Nobelit.

=*NORMAL POWDER.=--A smokeless powder which was said to have been adopted by the Governments of Switzerland, Sweden, Norway, Denmark and Finland. The following analyses were given in “Arms and Explosives,” 1917, p. 91--

Rifle. Shot-gun Powders. Date of Sample 1895 1913 1902 Nitrocellulose, insoluble 93·0 8·8 40·8 ” soluble 3·5 89·4 56·1 Resin 2·0 -- -- Moisture 1·5 1·8 2·0

=NORMANITE.=--A coal-mine explosive which was made by the Cotton Powder Co., and was on the old Permitted List--

Nitroglycerine 33·5 Collodion cotton 1·5 Potassium nitrate 44·5 Wood meal 8 Charcoal 1·5 Ammonium oxalate 11

Explosifs =O= are the chlorate explosives made in the French State factories. O1, O2, O4 and O5 are Cheddites (q. v.). O3 is a Sprengel explosive, and is dealt with under the heading of Prométhée.
