WATER ANALYSES 
During the year 1899 systematic examinations of the drinking water have been 
made. In collecting the samples the usual precautions to prevent extraneous 
contamination have been taken. The analyses show that the water is uniformly very 
good. No pathogenic forms have been isolated, and the average number of bacteria 
per cubic centimetre has been well below 100 (Koch's Standard). A very large 
number of analyses have also been made for the purposes of the Water Committee, 
and these appear in the separate report of the Water Committee.
