Book excerpt: 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.

Book excerpt: Excerpt from The Journal of the American Chemical Society, 1894, Vol. 16 The waste to which I desire to call your attention to-day is not that which normally takes place in the production of a crop, but that which is incidental to the cultivation of the soil and to a certain extent unavoidable. My purpose is to develop, if it be possible, the relations of agricultural chemistry to this waste, with the purpose of pointing out a course by which it can be returned and in what way we may at least reduce to a minimum the unavoidable removal of valuable plant food. You have all, perhaps, surmised the character of this waste; I refer to the denudation of fields by water and to the removal of soluble plant food by the percola tion of water through the soil. The losses due to the denudation of fields are purely of a mechanical character. The natural forest, or the natural cover ing of grass over an area of soil, prevents, to a large extent, the denudation due to heavy downpours of rain. The removal of the forest, and the destruction of the grass by cultivation, leave the soil in a condition in which it is unable to resist the action of flowing surface water. The muddy character of the water in all streams bordering on cultivated hilly fields after a heavy rain storm is a familiar instance of the tremendous energies which are exerted by a heavy downpour of rain in the carrying of the soil into the streams and its transportation towards the sea.

Known volumes of air, approximately twenty liters each, were drawn through solutions of iodine, and later these solutions were analyzed for their sulphuric acid content by the ordinary gravimetric method. An approximate calculation as to the amount of sulphur dioxide by volume in a million parts of air could then be made. A summary of the results is shown in Table I. It may be said that a second series of determinations carried out in the autumn of 1905 corroborated the results here given, although carboys were used as aspirators, two absorption bottles in train were employed, and forty liter samples of air were analyzed.
