PROCEEDINGS FOR 1915 XXVII 



request that if possible, more accurate record be kept of deaths from 

 gas poisoning by their Division Registrars. 



2. That the Department of Inland Revenue be requested to in- 

 struct their gas inspectors to determine the percentage of carbon 

 monoxide in illuminating gas at the same time as they make the exami- 

 nation for sulphuretted compounds. 



We have found that on account of the war it has not been 

 possible to obtain the European statistics; your Committee therefore 

 wishes to submit this report merely as a report of progress, and asks 

 permission to continue its work for another year. 



In conclusion we wish to return our sincere thanks to all those 

 who have so kindly and promptly responded to our requests for 

 information on this most important subject. 



Appended is a list of the cities from which we have received 

 information as to the use of carbon monoxide in their gas supplies. 

 There are very few records to be had of deaths by asphyxiation from 

 this gas, either accidental or suicidal, but there are several Parlia- 

 mentary papers and pamphlets, obtained from many sources, accom- 

 panying this report.
