Priming-case, a small tin case, about the size and shape of a cartridge, for the purpose of keeping a certain quantity of gunpowder, for priming, constantly ready and dry. This rational and econonomical invention, should be universally adopted.

Priming-wire, in gunnery, a sort of iron needle employed to penetrate the vent or touch-hole of a piece of ordnance, when it is loaded, in order to discover whether the powder contained therein is thoroughly dry, and fit for immediate service; as likewise to search the vent and penetrate the cartridge, when the guns are not loaded with loose powder.

PRIMIPILARII, PRIMOPILARII, or PRIMIPILARES, among the Romans were such as had formerly borne the office of primipulus of a legion. The banner was entrusted to his care. Among other privileges which the primipilarii enjoyed, they became heirs to what little property was left by the soldiers who died in the campaign.
