129) be the axis of a pivot, and let RPC be a portion of a curve such that at any point P the secant of the obliquity to the normal of the curve of a line parallel to the axis is inversely proportional to the ordinate PY, to which the velocity of P is proportional.
Whilst others have gone for whatever musical fad there may be fashionable at the time, PY has just done his own thing.
