Note 302 — Chapter VII

This mountain, which, with its neighbor Popocatepetl, forms the great barrier—the Herculis columnæ—of the Mexican Valley, has been fancifully likened, from its long dorsal swell, to the back of a dromedary. (Tudor’s Tour in North America, Let. 22.) It rises far above the limits of perpetual snow in the tropics, and its huge crest and sides, enveloped in its silver drapery, form one of the most striking objects in the magnificent coup-d’œil presented to the inhabitants of the capital.
