A three-page encyclopedia article on hair from Chambers's Encyclopedia (1881). It describes hair structure (shaft, bulb, follicle, cortex and medulla), pigment and colour, physical properties such as strength, elasticity and hygroscopy, and differences between races. It also compares hair with wool, noting that wool has a serrated surface and felts while hair does not, and closes with the functions of facial hair, graying, and cases of extreme length or abnormal hairiness. Three figures show a hair bulb section, a hair surface, and wool fibre.
