ANNUAL ADDRESS. XXI. 



The great reduction in the death rate in the City of Sydney 

 and the suburbs, due to improved sanitation, from 18 - 9 per 

 thousand in 1888 to 13*4 per thousand in 1896 means the 

 saving of 2,200 lives annually. The reduction of the rate in 

 what may be termed preventible diseases has been much greater, 

 for, taking the five years 1884 to 1888 inclusive, and comparing 

 them with the five years ending 1896, the death rate from 

 typhoid was only one-third of that of the former period. 



I might go on for a long time instancing the savings in cost of 

 manufacture or in preventing loss of life that arise from a proper 

 scientific knowledge, whether it is the knowledge of the Chemist, 

 or Doctor, or the Engineer, but I have taken up too much of 

 your time already with a very rambling address, and must leave 

 unsaid much that I had intended to bring before your notice, 

 and have now only to thank you for your kind attention.
