CHAPTER Vn. 3ets. Jets may be divided into three broad divisions, the oxy- calcium, the blow-through, and the mixed, to v^hioh we have already referred (pp. 12 and 13, Figs. 7, 8, and 9). The various features which these jets possess in common have been considered; it only remains to discuss those points in which the types diifer. The oxy-calcium, as being the simplest and the one which yields the least amount of light, will be first dealt with. The oxy-caloium jet, as it is generally styled (Kg. 7), should be called more properly the oxygen-alcohol jet, since all limehght jets would reasonably come under the title oxy- calcium, meaning one employing oxygen and lime. This form of the limelight does not give anything like so much light as the blow-through jet, or stiU more as the mixed jet, but is never- theless a simple and convenient iUuminant, and one much more brilliant than any oil lamp. It consists of a cylindrical reservoir, from which a pipe leads to the front of the jet and terminates in an upright tube containing a cotton wick. Just behind this is the lime pin. The oxygen is supplied by means of a tube which is fixed under the reservoir, and which passes along close to the other tube and bends round in front of it, terminating in a nozzle. The reservoir is filled with methylated spirit, the wick-holder being filled with straight lengths of the loose cotton wick supplied for the purpose, which should not be packed too closely together, and the ends of which should stand out about a quarter of an
