The Status of Chrome Leather I n spite of the commercial importance of chrome-tanned leather, there is still some discussion as to the relative merits of chrome and vegetable-tanned leathers. At the forthcoming conference of the American Leather Chemists Association, which is to be held a t the Monmouth Hotel, Spring Lake, N. J., June 18 to 20, a committee report on the methods for standardizing the analysis of chrome-tanned leather will be presented by A. C. Orthman, which will prove of interest to a large number of chemists and tanners of chrome leather. The chemistry of chrome tanning, while perhaps better under-

stood than that of vegetable tanning, is not without its complications, and a paper will be presented a t the conference by K. Gustavson on “A New Method for Determination of Degree of Complexity in Chrome Salts.” A very good opportunity for a discussion of the relative merits of chrome and vegetable-tanned leathers will be afforded on the occasion of the presentation of a paper by Lloyd Balderston on “A Comparison of Chrome and Vegetable Tanned Belting Leather.” It is expected that a large attendance of representatives of the leather and allied industries will be on hand a t this conference a t Spring Lake, which is within easy access of New York.
