passing the gas over fuming sulfuric acid; the oxygen was removed 

 by means of stick phosphorus, and the carbon monoxide was removed 

 by cuprous chloric!. A part of the remaining gases; nitrogen, marsh 

 gas and hydrogen, was exploded over mercury, and from this the 

 amount of each of the two latter was calculated, and the nitrogen was 

 thus absorbed, and the other gases were determined as before. This 

 gas contains over 90 per cent, of marsh gas, a gas producing but 

 little light, but valuable for heating purposes. It contains small 

 quantities of carbon monoxides, carbonic acid and oxygen with traces 

 of nitrogen and olefiant gas. Like most natural gases it is, as far as 

 examined almost entirely free from hydrogen. It is on account of 

 the small quantity of olefiant gas or other illuminating materials, 

 that the gas is not burned satisfactorily in an ordinary "bat wing" 

 burner, but a special burner, must be used. The results of some of 

 the analyses were as follows:

 DISTRSBUTION AND USE OF CAS. 



As the gas is produced at the wells and held in the mains at 

 tremendous pressure it is of the utmost importance that before it is 

 supplied to customers it be reduced in pressure to nearly the 

 same pressure as that on the ordinary street mains, where illuminating 

 gas is used. The regulators that are used for this purpose are of 

 various patterns, but in the better class the gas is passed through a 

 governor, in which the pressure is reduced as desired, by weighting 

 the end of the lever, and then through the valve to a gas holder. 

 By means of an automatic valve the pressure on the mains is kept 

 constant. 



The gas is sometimes used in the ordinary burner, provided with a 

 special lava tip, but as it contains so little illuminating material, and 

 as in order to get sufficient light it is allowed to "blow," the light is 

 not satisfactory, except perhaps for a street lamp. There are two 

 special burners that are very largely used with natural gas and with 

 poor illuminating gas. One of these is the Welsbach Incandescent, 

 in which a " mahtle " of oxides of some rare earths is heated to a
