CROION POISONS. A Tola ef Tribulations?Professor (bnndler ?n Croton Water Poison*. The annual report of tne Doara of llealtn, now in press, contains several chapters by i'rofeasor chamJler, cuemlst of the Board. An interesting synopsis is given below:? POttTY. The water supplied to the cltlsens of Mew York, at the liberal rate or slxty-Uv* gallons to each person dally, 1* by the various branches of the Crotou rlror from an area of 838 square mile* in Westoheeter, rutnam and Dutchesa oouulie*. The character of this water shed is a auQlcient guarantee of the purity of the water. The surface of alltclous gravel rests on bard uaureiman Knell*, and I* open pasture or woodland, with few swain pi. No factories Hue the streams, which are liable to contaminate the waters with refuse chemicals, aud no towns or large villages eaist In tbo district to pollute toe waters with sewage. A recent survey of the water-shed has indicated Qfteen points at which dams can be erected for tbn oreatlon of large storage reservoirs, whose joint capacity would he 67,0(10,000,0110 gallons, or a supply, at the present rate of for 1,000 days. On* of these danu. 650 feet lnug, Is now In process of construction at Boyd's Corner, In Putnam county, twenty-three miles from the mouth of the When this dam Is completed It will flood an area of Soil acres, and the reservoir thus produced will contain ?,1560,206,607 gallons, or a supply for titty to tifty-flve days of drouth. LEAP IN THE WATER. On this subject Professor Chandler remarks:? The attention of the Metropolitan Board of Health having been oatled to the frequent cases of chronic lead poisoning which occur In tho city, the chemist to the Hoard, O. P. Chandler, was directed to Investigate both the Crotou water and the varloua hair tonlos, washes, Ac., with a view to discovering the probable cause. Accordingly eiaminattofls were made of t'roton water which had becu in contact with lead for different lengths of time, under usually occurring clroumstances, of which tbs following are ?IIW loauui 1. A gallon of Croton water from a lead-lined cistern, In which it had stood for several weoks, was found to contain 0.n6 grain of metallic lead, J. A gallon of water which had remained six liours In the lead pipes of the chemist's residence yielded (l.tl grain metallic lead, a considerable portion of which was risible to the eye, In the form of minute white spangles of the hydreted uxycarbouute (FbO.HOi l*bO,OOJ). ft. U'uter drawn from one of the hydrants of the School of Mines Laboratory, in the middle of tne day, when the water was In constant motion, yielded traces of lead. This water roaches the srhool through about ltO to 160 feet of lead pipe. These results Indicate tbe source of many hitherto casrs of lead poisoning, and are or a character to alarm tbe residents of Mew York, and to lead them to adopt precautionary measure* for protection agaiust this lusldtous cause of disease. Many hare already introduced as a substitute for lead pips the "tln-llned" or "Icad-cucased blook tiu" pipe. t.'erlainlr no pains should be spared to Impress upon the importance of allowing tbe water to run for a few minutes before taking It for drinking or cooking purposes, especially early In the morning, aft *r the water has stood all night in the pipes. The habit of filling the tea kettle from the holler, or or using water from the boiler lor any purpose except washing, is very dangerona. Experiment Mo. 9 explains a case which recently occurred in New York. An elderly, gentleman was completely with paralysis or palsy. Els physician at once lead poison from his symptoms, and Instituted Inquiries which developed the fact that the patient had been using wheaten grits for dvsuemla. and that tha first dutvlnt the nmk In lbs morning bad bean to soalt them preparatory to boiling them. She ha>l therefore uted dally the water which had stood all night in the pipes. The occurrence, of a considerable portion of the lead-in experiment number two, In suspension, Instead of solution, is an additional argument for the use or the tllters, though It will of course be useless to employ them unless they ars frequently reversed, that they may hi; cleansed.
