7/13 _Fah._ _Lights_ are next in order. Gas hardly requires mention, as the care of it is limited to seeing that it is not turned too high, the flame in such case not only vitiating the air of the room with double speed, but leaving a film of smoke upon every thing in it. Kerosene is the oil most largely used for lamps; and the light from either a student-lamp, or the lamp to which a "student-burner" has been applied, is the purest and steadiest now in use. A few simple rules for the care of lamps will prevent, not only danger of explosion, but much breakage of chimneys, smoking, &c. |
