A two-page article from the trade journal Textiles on identifying textile fibers under the microscope and by simple chemical tests. It covers kemp fibers in wool, the litmus test for separating animal from vegetable fibers, and the differences between cultivated (raw and boiled-off) silk and tussah silk. A table compares wool and silk reactions to reagents, and the article ends with a note on mounting wool fibers for microscope slides. Page 2 also carries the start of an unrelated article on bearings and power transmission in textile mills.
