=Water Pollution Remedy.=--According to Dr. S. S. Kilvington, the Mississippi River received during the past year 152,675 tons of garbage and offal, 108,550 tons of night-soil, and 3,765 dead animals from only eight cities; the Ohio 46,700 tons of garbage, 21,157 tons of night-soil, and 5,100 dead animals from five cities; and the Missouri 36,000 tons of garbage, 22,400 tons of night-soil, and 31,600 dead animals from four cities. Doctor Kilvington urges the cremation of most of the refuse, and 23 out of 35 health officials consulted by him favored the plan. =Whooping-Cough.=--Mr. W. A. Stedman, superintendent of the Rochester Gas Works, gives his opinion:-- "The fumes of the substance used to purify gas are generally recognized as a specific for this disease. "The composition used for purifying gas is composed of wood shavings, iron filings, lime, and sometimes copperas. This substance cleanses the gas of the ammonia and sulphur it contains. If a child with the whooping-cough is allowed to breathe the fumes of the purifier after it becomes foul, immediate relief will be experienced. The fumes of the lime after it has been taken out are particularly beneficial. The lime, after it is taken out, begins to heat and throws off fumes strongly impregnated with ammonia. After breathing these fumes for a short time the cough seems to loosen, and two of these visits will generally cure the most obstinate case. "In Newport one winter, when I was superintendent of the gas works there, there was an epidemic of whooping-cough, and I treated over 200 cases, with the happiest results. I had so many patients that I was forced to put benches in the purifying-room. Once in awhile there are people affected with whooping-cough to whom this gas treatment gives no relief, but they are the exception rather than the rule. In nearly every instance it gives immediate relief and effects a positive cure. I know of many physicians who send all their whooping-cough patients straightway to the gas works. I know that it is a sure cure from personal experience, and we would be happy to extend the courtesies of our purifying-room to any person who is suffering from the disease."
