Abstract
The precipitation of phosphoric with titanic acid, by boiling an iron solution which had been reduced to the ferrous condition by sulpharetted hydrogen or sulphurous acid, was first noticed by E. H. Bogardus in 1874.* Since that time, as far as we are aware, not much has been published on the relation of these two acids to each other, and to silicic acid, in the ordinary course of analysis of iron ores. The following investigation may perhaps aid in clewing up some of the obscure points in the analysis of titaniferous ores. THE DETERMINATION OF PHOSPHORUS. From two to five grams of the finely powdered ore are weighed into a beaker and treated with about 50 c.c. of hydrochloric acid (sp. gr. 1.12), evaporated to dryness, and heated ih an air-bath for
