Synopsis of results of examination of water samples.—In the columns headed
dates and results, first the date of examination is given and then the minimum
number of cubic centimeters of water in which lactose fermenters could be found.
When these were absent in 60 c.c., the mark > is written before 60 to indicate
that the minimum quantity was something greater than 60 c.c. Unless otherwise
stated, filters refer to slow sand filters. The expression " Distributary system "
includes service reservoirs.
