Fig. 2 is a more powerful and convenient form of the same 

 apparatus, for disengaging chlorine, for diluting it with air, and 

 for propelling the mixture along pipes with very considerable 

 velocity, so as to ensure its thorough diffusion among the tim- 

 bers of a ship, and bales of merchandize, however closely 

 stowed. Every ship of war should be provided with such an 

 apparatus on each of its decks, and a few minutes working of 

 it would sweeten and disinfect, infinitely better than an hour's 

 combustion of gunpowder wetted with vinegar, 4he delusive 

 fumigation at present practised in the navy, under the appro- 

 priate title of the Devil, the patron of falsehood. The slightest 

 consideration of the gaseous products of burning gunpowder, 

 shows that they can exercise no decomposing influence what- 

 soever on contagious or fermentable filth, which chlorine 

 unquestionably does. In fig. 2, the orifice B of the gas gene- 

 rator is tubular, and rises about 18 inches high, so as to pre- 

 clude the chance of the relatively dense chlorine overflowing, 

 to the annoyance of the operator. But a few turns of the 

 fanner will draw off the chlorine from A, however quickly it 

 may be evolved. Through the pipe B, the chloride, previously 

 mixed with water, is introduced, and by the syphon-funnel
