Not identified. The contributor's article is motivated by "the great events of the last few weeks" in the Crimea, i.e., the siege of Sebastopol, the battles of Balaklava and Inkerman. The writer draws his information from various sources; a "practical work" compiled by "several experienced Artillery officers", John Henry Lefroy's Handbook for Field Service, certain instructions issued by the French Minister of War, and, as seems probable, his own military experience.
