to which are added a few per cent. of sulphate of iron. The incorporation is carried out with the assistance of a considerable quantity of water, which is afterwards evaporated off. The mixing is not very thorough. The explosive is a comparatively mild one, but is used sometimes for blasting basalt. In the German explosive the potassium nitrate may be replaced by the corresponding sodium salt. =AMMONCAHUECIT.=--In this explosive the potassium nitrate is replaced mainly or wholly by ammonium nitrate, and it contains not more than 15 per cent. of trinitro-toluene or trinitro-naphthalene or other nitro-body. The brand labelled “Fram” contains ammonium nitrate, not more than 25 per cent. of trinitro-toluene gelatinised with 4 per cent. collodion cotton, wood meal or other vegetable meal and neutral stable salts. The brand “Indra” is similar, except that it contains also not more than 10 per cent. potassium nitrate, and the percentage of trinitro-toluene may be raised to 20. =CAMBRITE= is a coal-mine explosive of the Carbonite type made by Nobels at Ardeer. It consists practically of Nobel Carbonite, to which 8 per cent. of a cooling agent has been added. Unlike most of the explosives on the old Permitted List, it passed the Rotherham Test with practically no alteration-- Cambrite.

Nos. 1A, 2A and 2A LF are ammonium nitrate explosives, whereas Nos. 3A and 5A are nitroglycerine explosives. =*CANNONITE= was a smokeless powder made by a firm called the War and Sporting Smokeless Powder Syndicate, Ltd. It consisted of about 86 per cent. of nitrocellulose mostly insoluble in ether-alcohol, and a few per cent. of barium nitrate, together with small quantities of some of the following: potassium nitrate, charcoal, lampblack, vaseline, rosin, stearine, dinitro-benzene, trinitro-toluene, potassium ferro-cyanide, graphite. For shot-guns the powder was of the forty-two grain type, dense and gelatinised. The rifle powder was colloidal. These powders were made in the ’nineties of the last century. =CARBITE D’ABLON= is a sort of Carbonite made in France-- Nitroglycerine 26 Potassium nitrate 33 Wood meal or flour 41 =CARBOAZOTINE.= See =CAHUECIT=.
