A continuation of a serial article on fabric analysis from Posselt's Textile Journal, January 1912, describing how to identify animal fibres by microscope appearance. It compares hair and wool, then covers cashmere, mohair, alpaca, llama, vicugna, guanaco, camel, goat, cow and calf, and horse hair, giving fibre lengths, colors and scale and medullary structure. Illustrated with microscope views and engravings of the animals. The scan also includes the start of a section on cotton carding.
