DIFFUSION OF SANITARY KNOWLEDGE. 19 



as I have indicated, the best efforts of the authorities and 

 of their medical officer will fail of their object. 



I have only, in conclusion, to add that it is most desirable to 

 have our people thoroughly informed in regard to sanitary 

 matters, in order that they may heartily and intelligently assist 

 in promoting what is really necessary for their own and their 

 neighbours' good. 



To further this desirable movement has been, I know, the 

 cherished object of the promoter of these " Health Lectures for the 

 People/' 



At the close of the lecture Dr Smart showed Professor Tyndall's 

 experiments by means of the lime-light.
