PRACTICAL OBSERVATIONS. 25

 ance, and indeed injury to the health of every one, and 

 most disgusting to those cognizant of its poisonous 

 effects. In the arcades and passages it is particularly 

 offensive and obnoxious, the atmosphere of those close 

 places being always contaminated by the pestilential ex- 

 halations. I may add, this must be still more so the 

 case in the smoking-rooms of our clubs. And I may
