          ==========================================================
Nobody since Newton has been able to use geometrical methods to the same
extent for the like purposes; and as we read the Principia we feel as when
we are in an ancient armoury where the weapons are of gigantic size; and as
we look at them we marvel what manner of man he was who could use as a
weapon what we can scarcely lift as a burden.
