REPORT OF THE KING INSTITUTE, GUINDY
TABLE XIV.
Synopsis of results of examination of water samples. — Most samples were
examined fully chemically and bacteriologically, but the details are not given in
order to avoid taking up too much space. Since on the whole the presence of
lactose fermenters is the most important criterian 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 some–-
thing greater than 60 c.c. Unless otherwise stated, filters refer to slow sand
filters. The expression “ Distributary system ” includes service reservoirs.
