Whyte notation
The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in "American Engineer and Railroad Journal". The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, groups of numbers being separated by dashes. Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.
Beauchamp-Feuillet notation
Beauchamp–Feuillet notation is a system of dance notation used in Baroque dance.
The notation was commissioned by Louis XIV (who had founded the Académie Royale de Danse in 1661), and devised in the 1680s by Pierre Beauchamp. The notation system was first described in detail in 1700 by Raoul-Auger Feuillet in "Chorégraphie". Feuillet also then began a programme of publishing complete notated dances. It was used to record dances for the stage and domestic use throughout the eighteenth century, being modified by Pierre Rameau in 1725, and surviving into at least the 1780s in various modified forms.
