if it is considered that an ordinary bar of laundry soap generally will contain: Fatty anhydrides Rosin anhydrides Sodium oxide, combined as soap with the above Unsaponifiable matters, from both the fatty and rosin matters, mineral oil, etc. Perfume, or essential oils Sodium carbonate, as filler and hardener Sodium hydroxide, free or free and combined with silicate Sodium silicate, free or hardener, and neutralizer of caustic Sodium chloride Sodium sulfate Unsaponified matter, particularly in cold soaps, rarely in laundry soaps Lime, magnesia, aluminum, iron, or other metallic salts in small amounts Water Glycvrin, always present t o some extent Naphtha, borax, ammonium chloride, etc., always possibilities
This does not begin to exhaust the list, but covers those things usually present, and in getting up a scheme of analysis the efTect of these things on one another and towards the reagents must always be borne in mind. We have methods to determine with considerable accuracy any of the above ingredients, but we would hesitate to try to get up a standard method by which they could all be found in turn. I t takes special methods and special apparatus for many of them. WILSONH. Low THECUDAHY PACKING COMPANY OMAHA,NEBRASKA September 5, 1919
T W O LETTERS ON THE TREATMENT OF LOW-GRADE NICKEL ORES Editor of the Journal of Industrial and Engineering Chemistry: It was with much pleasure and interest that I read the article by Mr. C. W. Davis [THISJOURNAL, 11 ( ~ g ~ g6441 ) , relative to thc. treatment of low-grade oxide nickel ore. While appreciating his courtesy in mentioning my name in his acknowledgment in connection with a reduction test on nickel ore of North Carolina, I wish to emphasize that the reduction was done on my own request and initiative, Mr. Davis being kind enough t o supply me the ore sample. Moreover, the idea of rendering the refractory nickel ore soluble by meam of a reducing roast with gas, without fusing the ore, preventing reoxidation by cooling, originated with me. The results of this reduction test confirmed my theory. No doubt Mr. (2. W. Davis, a friend of mine, must have not purposely forgotten this point in his acknowledgment, and it is therefore with friendly feelings that I bring this matter to his attention. 5 WILHELMINA LAAN M.

............ Editor of the Journal of Industrial and Engineering Chemistry: Referring t o the above criticism of the paper which was published in the July issue of your journal, Mr. M. H. Caron is correct in stating that the idea as well as the actual reduction of the nickel ore was his. I regret exceedingly that this point was not covered in my acknowledgment in that paper, for I had no thought of claiming t o be the originator of a method of ore ti eatment which has been patented by Mr. Caron.
