Book excerpt: Excerpt from The Analysis of Black Powder and Dynamite Although descriptions of the methods of analysis of explosives are to be found in many books on explosives, and in works on engineer ing chemistry or chemical analysis, most of these descriptions are incomplete and lacking in details.
