Micrographic Study of Leather

Nature volume 78, pages 1819 (07 May 1908) | Download Citation



UNDER the title “Étude micrographique du Cuir,” M. Henri Boulanger has published in the Bulletin de la Société d'Encouragement for February of this year a series of interesting drawings showing the microscopic appearance of various sections of raw and tanned hide. The chief interest in these consists in the demonstration of the changes which take place in the skin during the process of tanning. About thirty years ago a very similar study was undertaken by the late Franz Kathreiner, of Worms, on the microscopic preparations of raw and tanned calf skin, in all the various stages of the tanning process, and the writer has had the privilege of seeing these very beautiful preparations; unfortunately, Kathreiner's results were never published.
