Nitrocellulose, insoluble 40·5 ” soluble 20·5 Metallic nitrates 30·0 Nitro-compound 5·0 Vaseline 2·7 Moisture 1·3 =*FILITE= was a smokeless powder formerly used in the Italian services. It was a Ballistite consisting generally of equal parts of nitroglycerine and collodion cotton, to which 0·5 to 1 per cent. of aniline or diphenylamine was added as a stabiliser. It was gelatinised with a solvent and drawn out into cords. =FLAMMIVORE.=--A Belgian coal-mine explosive made at Arendonck-- O. Ammonium nitrate 70 Barium nitrate 15 Cellulose 5 Dinitro-toluene 10 Charge limite 100g. I. Blasting gelatine 4 Ammonium nitrate 82 Potassium nitrate 10 Rye flour 4 Charge limite 500g. III. Nitroglycerine 6 Ammonium nitrate 70 Ammonium sulphate 9 Barium sulphate 7 Dextrin 8 Charge limite 650g. In the United Kingdom this is “authorised” but not “permitted” for use in dangerous mines. =FLOBERT= ammunition consists of small cartridges, like detonators, charged with a small quantity of mercury fulminate, and some antimony sulphide and potassium chlorate. It is used for target practice and shooting small birds. =FOERDER SICHERHEITSSPRENGSTOFF.=--A German coal-mine explosive containing ammonium nitrate, not more than 4 per cent. of blasting gelatine, mono- and di-nitro-aromatic compounds, vegetable meal and neutral salts. =FOERDIT.=--A German coal-mine explosive containing nitroglycerine gelatinised or ungelatinised, carbohydrates, glycerine, nitro-compounds, inorganic nitrates and sodium or potassium chloride. Ammon-Foerdit is a similar mixture, except that it contains a larger percentage of ammonium nitrate and no other inorganic nitrates. The nitroglycerine is gelatinised, and there is a little diphenylamine. The following are examples of these two explosives-- Foerdit. Ammon-Foerdit. Nitroglycerine 25·5 3·8 Collodion cotton 1·5 0·2 Ammonium nitrate 37 85 Nitro-toluene 5 -- Dextrine or flour 4 4 Glycerine 3 2 Diphenylamine -- 1 Potassium chloride 24 4 Ammon-Foerdit F, which has been introduced recently, contains up to 10 per cent. of potassium perchlorate and is similar to Astralit V. =FORCITE.=--A variety of gelatine dynamite or gelignite made in Belgium. It contains blasting gelatine 36 to 64 per cent., sodium or ammonium nitrate, wood meal, magnesia and sometimes bran. An American explosive of the same name is a dynamite containing wood tar--
