=LIGNOSIT= is a German blasting explosive containing a considerable percentage of ammonium nitrate. Lignosit I. contains also aromatic nitro-compounds, of which not more than 15 per cent. must be trinitro-compounds or wood meal, and not more than 6 per cent. of potassium nitrate, not more than I per cent. of collodion cotton and bauxite or salts, such as sodium chloride or carbonate. Lignosit II. may contain up to 10 per cent. of collodion cotton, but no wood meal or nitro-compounds. It is somewhat sensitive. Lignosit III. differs from I. in that it may contain up to 4 per cent. of blasting gelatine and contains no bauxite. The object of adding the neutral salts is evidently to make the explosive safer in coal mines. When intended for this purpose it is called Wetter-Lignosit I. or III. Lignosit IV. consists of ammonium nitrate, not more than 13 per cent. of trinitro-toluene, not more than 13 per cent. of aluminium powder, and wood meal. =LITHOFRACTEUR= is a name that has been given to more than one explosive. One introduced about 1873 by Krebs and Co. of Deutz, near Cologne, consisted of nitroglycerine absorbed in kieselguhr mixed with nitrates, charcoal or coal and sulphur. Some of it was imported into England at one time. =LOEWENPULVER= or Castroper Sprengpulver is a German blasting powder consisting of a compressed or granulated mixture of sodium nitrate, manganese dioxide, sulphur and carbonaceous substances such as briquette powder or coal. It may also contain potassium nitrate, wood meal or tar. =LOMITE NO. 1= is an American coal-mine explosive on the Permissible List. It is a low-grade dynamite containing hydrated salts. =LOWINITE NO. 2-B= is an American coal-mine explosive on the Permissible List. It is an ammonium nitrate explosive. =LUXIT I.= is a German blasting explosive consisting of ammonium nitrate, not more than 17 per cent. of trinitro-toluene, and not more than 5 per cent. of wood meal. =LYDDITE.=--A high explosive used in the British Services for filling shell. It consists simply of picric acid, which is melted under proper precautions and poured into the shell. *Poudre =M= is a shot-gun powder made by the French Government, and is the one that is most used in France. Its composition is-- Nitrocotton 71 Barium nitrate 20 Potassium nitrate 5 Camphor. 3 Binding material 1 The nitrocotton has a solubility of only 15 or 20 per cent., and is partially gelatinised with ether-alcohol aided by the camphor. It is granulated under edge runners, granulated and drummed. =MACARIT.=--A Belgian high explosive for filling shell-- Trinitro-toluene 30 Lead nitrate 70 It has a high density and is not deliquescent. For equal weights its power is less than that of trinitro-toluene or picric acid, but for equal volumes it is somewhat greater. =MARKANIT.= See =SILESIA=. =MARSIT.=--A sort of Oxyliquit. Liquid oxygen is passed into a linen bag containing soot.
