A Bnnsen Burner for icetylene. An in- 

 teresting item regarding the use of acetylene 

 as a heating agent occurs in the Chemical 

 News. A. E. Munby MTites: "The cheap 

 production of calcium carbide has placed a 

 powerful illuminaut within the reach of those 

 who possess no gas supply, but so far little 

 has been heard of the use of acetylene as a 

 keating agent. Our laboratory is, so far as 

 we know, the first to make use of the gas 

 for this purpose. We employ a Bunsen 

 burner of special dimensions, the tube being 

 five millimetres in internal diameter. A 

 slightly wider tube may be used, provided 

 the mouth be curved inward, so that the 

 actual exit does not exceed the diameter 

 mentioned ; if larger, the flame tends to 

 strike down. The gas jet is very small, be- 

 ing only capable of delivering about one 

 cubic foot of acetylene per hour under six 



inches water pressure, such a rate of con- 

 sumption giving an ordinary working flame. 

 The air holes and collar are arranged as in 

 an ordinary Bunsen, the exact size of the 

 former not being of much importance, pro- 

 vided they be large enough to admit the air 

 required. A generator capable of giving gas 

 under seven inches water pressure with the 

 full number of burners in use is required. 

 The heating effect of the flame is, of course, 

 very great, enabling one to dispense with the 

 blowpipe for some operations, such as small 

 fusions. ... It would seem that in practice, 

 for equal volumes burned, the acetylene has 

 nearly twice the heating power of coal gas."'
