In the operation of the filters of the London Water-Works, and indeed of all the European works where filters are used, the test of filtration is based on the number of bacteria of all kinds found in the filtrate. While numerous special examinations have been made of the kinds of bacteria remaining in water after filtration, no continuous tests or standards of efficiency based upon the varieties found have been made so far as the author is aware. Evidently if the bacteria removed are of the harmless kinds, while those that remain are of the pathogenic varieties, no great benefit can be expected from simple filtration of a polluted water.
