A cur-rent has apparently no effect, in many such cases, inpreventing the deposition of scale. The Author hasknown hard scale to form in the cones of a Giffard in-jecter under his charge, where the steam was movingwith enormous velocity, and loudly whistling as itpassed. Instances are well known of the explosion, with fataleffect of open vessels, in consequence of the action abovedescribed. Mr. G. Gurney, in 1831, gave an account ofsuch an explosion of the water in an open cauldron a
