CH. IV] DO AND DO NOT WITH THE LIME LIGHT 117 § 186. Summary of Chapter IV: Do 1. Use gas cylinders which are plainly marked Oxygen and Hydrogen, and have righthanded screws for the oxygen and left-handed screws for the hydrogen (§ 154). Be sure that there is plenty of gas in each (§ 156) 2 . Connect the cylinders with the burner by means of rubber or metallic tubing, colored to correspond with the cylinders (OorH) (§ 154, 159, i59a). 3. In starting the burner, turn on the hydrogen or its substitute first and light it, then turn on the oxygen slowly (§ 160). 4. Heat up the lime slowly by having it at some distance from the flame (§ 162). 5. Turn the lime occasionally so that the pit will not get too deep (§ 164). 6. In putting out the lamp, turn off the oxygen first, then the hydrogen after a moment. 7. If the light snaps out, turn off the oxygen then the hydrogen. Turn on the hydrogen, light it and then turn on the oxygen slowly as in (3). Do NOT i. Do not use gas cylinders which are not plainly marked. Do not start an exhibition unless there is plenty of gas. 2. Do not be careless in connecting the cylinders with the gas burner. 3 . Do not turn on the oxygen first. Oxygen is last on, first off. 4. Do not turn the full heat of the O-H flame against a cold lime which is close up to it. 5. Do not let the lime stay too long in one position. Rotate it occasionally. 6. Do not turn off the hydrogen first, but turn off the oxygen first. Oxygen is on last, off first. 7. Do not leave the gases turned on if the light snaps out. Oxygen off first, then Hydrogen.
