5. Indirect as is the manner in which the foregoing advantages 

 accrue, they are none the less valuable. But in handing over 

 this work local authorities would have opportunity of making 

 many direct stipulations. They would require that receptacles 

 be tlioroughly cleansed before being replaced ; that escape of 

 effluvium from them should be prevented before removing 

 them ; and, perhaps, that they should be disinfected. 



I take advantage of this opportunity to explain something recently 

 said as to cleansing, which 1 observe has been misunderstood in several 

 quarters and confused with disinfection. A receptacle which is carefully
