Thus bold, independent, unconquer'd, and free,
Her bright course of glory for ever shall run:
For brave Caledonia           must be;
I'll prove it from Euclid as clear as the sun:
Rectangle--triangle, the figure we'll chuse:
The upright is Chance, and old Time is the base;
But brave Caledonia's the hypothenuse;
Then, ergo, she'll match them, and match them always.
