 by Sosman, Mr. Addicks outlined the possibilities of house heating by 

 artificial gas. LeClerc inquired about the danger to life from faulty

 as a municipal regulation not now in common use but of considerable 

 importance. 



Liquefied natural gas: With exhibit of apparatus. Dr. W. O. Snell- 

 ing, Chemist of the Bureau of Mines. Discussion: The relative heat- 

 ing values, temperatures obtainable with oxygen, and usefulness for 

 cutting and welding, of this gas as compared with acetylene and with 

 hydrogen were discussed by Cushman, CO. Bond, and Crawford. 



The 216th regular meeting was held on May 9 at the Cosmos Club.
