   • 1877, John Joseph Henry, Account of Arnold's Campaign Against Quebec‎, J. Munsell, page 171:

     In appearance, the bharal resembles both a sheep and a goat. Its horns are smooth, rounded and form a curve backwards over the neck. The fur is brownish grey in colour which attains a slaty grey hue in winter and becomes browner in summer. In Kumaun the bharal is found in the desolate tracts of northern Pithoragarh, usually on the slopes of the main Himalayan range where it lives between the timberline and the snowline.

     AROUND six years ago, Hyundai figured a 10-year warranty was not enough to attract shoppers and conjured up daring design for more attention. Sonata was the first to get the Fluidic Sculpture makeover, but the fifth-generation Elantra ended up being the swoopiest of the fleet. Hyundai’s newest gamble? Toning down those curves. […] Laugh at that detail now — you won’t when the sun is blinding you at 75 miles an hour on a curve.

3. A grading system based on the scale of performance of a group used to normalize a right-skewed grade distribution (with more lower scores) into a bell curve, so that more can receive higher grades, regardless of their actual knowledge of the subject.
