Not illustrated. 1886 Excerpt: ...forms of insect life as Daphnia pulex, anguilula, 4c., have been noticed. But in no single instance have the water-tests, either chemical or biological, given any grounds for the belief that the Berlin supply contained any matters injurious to health. That is to say, that none of the micro-organisms have, on pathological grounds, revealed any indications of a dangerous character. The report contains very numerous tables of analyses and six sheets of diagrams. Mr. Higgin. Mr. G. Higqin observed, in reference to filtration through sand, that seven or eight years ago he had occasion to make a series of experiments in filtration, with the object of ascertaining the best method of purifying the water of the River Plate, which was used for the supply of Buenos Ayres.1 It was stated in the Paper that the London Companies succeeded in eliminating 96 per cent. of micro-organisms from their water by means of a simple filtration through a bed of fine sand from 3 to 4 feet thick, at a speed of from l gallon to 2 gallons per square foot per hour. If this was so, it seemed evident from his experiments that the engineer might be called upon to deal with suspended particles smaller even than micro-organisms, and for whose elimination sandfiltration was useless. The River Plate was a delta-forming river, and like all rivers of that class, its waters are highly charged with suspended matter. Simple repose for twenty-four hours was sufficient in most cases to allow of the deposition of the greater part of this suspended matter; but there remained behind matter in suspension in a state of most minute subdivision, and giving a yellowish opalescent character to the water, which it appeared almost impossible to get rid of. Passing it through three folds of fine filter-paper...
