REPORT OF THE KING INSTITUTE, GUINDY
TABLE VI.
Synopsis of Results of Examination of Municipal Water Samples.
Most samples were examined fully, chemically and bacteriologically, but the details are not given in order
to avoid taking up space. Since on the whole the presence of lactose fermenters is the most important criterion,
it alone is here recorded.
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.
An asterisk denotes that the supply has been adversely commented on in the body of the report. The
comment "New " implies that the supply was examined for the first time this year.
