Frizzled

Another difference between the aurochs and the bison is the length of the hair; the neck, shoulders, and throat of the bison are covered with very long hairs; while the aurochs have all these parts covered with a short hair, resembling that of the rest of the body, the front excepted, which has frizzled hair.

Who there frequents at these unmodish hours, / But ancient matrons with their frizzled towers, / And grey religious maids?
