(HARRISON A \anderleck] ANALYSES OF OTTAWA RIVER WATER 



18 



Shutt and Spencer from their analyses of the water taken at 

 Ottawa, already quoted, class it as a good potable water. 



Through the kindness of Dr. John A. Amyot, Bacteriologist of the 

 Ontario Provincial Board of Health, we are enabled to publish the 

 bactej-iological findings of the water taken above the intake or from 

 the taps in the city of Ottawa. We have arranged these in two groups, 

 under winter and summer conditions, winter conditions being when the 

 river was frozen over. 



Winter Conditions (River frozen over). 



Summer Conditions (River free of ice).
