(n.) The narrow, hollow part of a gamopetalous corolla.
(n.) A priming tube, or friction primer. See under Priming, and Friction.
(n.) A small pipe forming part of the boiler, containing water and surrounded by flame or hot gases, or else surrounded by water and forming a flue for the gases to pass through.
(n.) A more or less cylindrical, and often spiral, case secreted or constructed by many annelids, crustaceans, insects, and other animals, for protection or concealment. See Illust. of Tubeworm.
