Show . Filtration and Typhoid. f (New York World.) ft Some important facts and figurr .-; 1 ; may be gathered from Dr. Neff's report on typhoid fever conditions In Phila- delphia, showing a remarkable de- f crease In the number of cases of that disease since the partial Introduction j ! of filtered water in that city. ) In the year 1906, when only a sma'l . J part of the city was supplied wit'i i f water from the filtration system, f f there were 9,721 cases. In the follow- ill ing year, when the area covered by th. ! filtration system had been considerably !f j extended, there were 6,721 case3. Since i ' that year and with the constantly in- j I creased extension of the area serve 1 S , with filtered water there has been a 3 v notable decrease in the cases of this disease, the number of 1908 being only 1 3,562, or only a little more than a third (f as many as In 1906, which was a record 1 year. For the past six months of the ; present year there were only 1.3."S t 1 cases, and it Is thought tne entire num- ! . ber of the present year, based on tho . J decreasing percentage, will not be ovei- i if 2,000. ! I Of course, even 2,000 eases of typhoM are far too many for a city of Phila- j delphia's population, or. for that mat- j J ter, for any city, but even that number f will probably be greatly reduced next year. . ' Water, however is not the only I means by which the typhoid germ ' f conveyed. Milk, fruit and uncooked J vegetables may also be the .bearers of J the disease germ, but in general wate'" : is th-3 usual means of communication, j and, happily, al! progressive cities now j recognize that fact and spare no pains I or expense to secure a pur watei 1 ' supply, ? j V '.hi |
