NOTES ON THE BACTERIOLOGICAL EXAMINATION 

 OF WATER FROM THE SYDNEY SUPPLY. No. IV. 



By Dr. Oscar Katz. 



Having been interrupted for about six weeks I was not able to 

 take up again the bacteriological examination of Sydney water 

 until the 29th of last April. From this date up to the 26th inst., 

 however, I examined sixteen samples of this water, derived again 

 in all the cases from the tap in the Laboratory of the Linnean 

 Hall. The following table will best convey an idea of the results 

 obtained so far as the quantity of bacterial colonies, referred to 

 1 ccm. of the water under consideration, is concerned.
