![of the Bureau of Chemistry, has been kind enough to furnish the following memorandum in regard to the tanning of small pieces of normal hide treated by the Seymour-Jones and Schattenfroh processes of disinfection. No marked differences in color were noted among the various pieces of tanned leather. Slight differences, due to difference in thickness, were noted in pliability, but these did not appear to be connected with the disinfecting treatment. No marked difference could be detected in the appearance of the grain of the leather. All the pieces cracked when severely bent, owing probably to excessive tannin in the grain of the leathers. The treated leathers did not display more pronounced cracking than those which were not treated. Microscopical examination of the hide fibers after deliming and of the leather fibers after tanning shows no marked differences among the several pieces of hide. The results in general seem to indicate that the several treatments have not injured the hides. The evidence, however, is not sufficient to permit of definite conclusions being drawn at this time. More extended work in commercial tannery, using whole hides, has been planned to determine definitely whether any of the disinfectants result in the production of inferior leather. Since tanning is a slow process, it will require from nine months to a year to secure these data. Mr. Veitch also states that all the leathers gave reactions for chlorids, but that the leathers treated with disinfectants apparently contained larger amounts of chlorids than the other leathers. It seems, then, so far as the evidence at hand permits any conclusion at all, that neither the Seymour-Jones method nor the Schattenfroh method exerts any injurious effect upon hides or leather. literature CITED (1) Anthrax Investigation Board for Bradford [England] and District.
