Portrait of Alfred George Greenhill Alfred George Greenhill,  1911 Encyclopædia Britannica (1911)

“ Friction on the point of the top may be supposed to act like a tap in the direction opposite to the precession; and so the axis of a top spun violently rises at first and up to the vertical position, but falls away again as the motion dies out. Friction considered as acting in retarding the rotation may be compared to an impulse couple tending to reduce OC′, and so make K and K1 both move to the exterior of the hyperbola, and the axis falls in both cases. The axis may rise or fall according to the direction of the frictional couple, depending on the shape of the point ”

“ Business, though feverish, was good; and many fortunes of our day had their origin in these excited business years of 1863 and 1864; when sales were easily made, most transactions were for cash, and nearly everyone engaged in trade or manufactures seemed to be getting rich. There must have been still considerable financial strength in reserve and, as the value of property depended largely on a stable government, ample funds for its maintenance would have been forthcoming in a supreme crisis. ”
