Excerpt from The Journal of the American Chemical Society, 1896, Vol. 18 HE want of a rapid method of determining with a close approximation the amount of lime and sulphuric acid in drinking water led me to the study of the opacity of fine White precipitates suspended in water. I precipitated in weak solu tions lime with ammonium oxalate, and sulphuric acid with barium chloride. Then measured the height of a column of the liquid containing the precipitate through which the flame of a common candle was just invisible. I expected only a rude approximation, but to my surprise, I found that between cer tain limits, an accuracy is attainable equal to that of the ordi nary volumetric methods.
