72 Proceedings. 



Dr. BOTTOMLEY introduced the subject of the death- 

 rate and recent correspondence in the local newspapers on 

 smoke abatement. In the discussion which ensued it was 

 suggested that if the adoption of smoke-consuming furnaces 

 were to be accompanied by the abolition of tall chimneys, 

 the advantages of diminished smoke might possibly be off- 

 set by the invisible deleterious gases being concentrated in 

 the lower part of the atmosphere, instead of being diffused 

 at an altitude where they would be unlikely to be injurious. 

 Mr. R. F. Gwyther raised the question whether a smoke- 

 less fire might not give off carbon monoxide, and asked 

 how this gas would be eliminated from the atmosphere. 

 Mr. John Angell argued that the apparently perfect com- 

 bustion in well-arranged smokeless furnaces implied the 

 absence of the monoxide from the products, but admitted 

 that in the case of smokeless house fires or stoves the danger 

 alluded to by Mr. Gwyther might exist.
