When the sky is darkened suddenly, and the atmosphere grows thick and stifling, the lower ranks of creation entertain the ominous sense of a coming tempest. The birds fly to the thickets, the wild creatures retreat to the closest covers which their instinct gives them the habit of frequenting, and domestic animals show their apprehension of the approaching thunderstorm by singular actions and movements inferring fear and disturbance. It seems that human nature, when its original habits are cultivated and attended to, possesses, on similar occasions, something of that prescient foreboding, which announces the approaching tempest to the inferior ranks of creation. The cultivation of our intellectual powers goes perhaps too far, when it teaches us entirely to suppress and disregard those natural feelings, which were originally designed as sentinels by which nature warned us of impending danger. Something of the kind, however, still remains, and that species of feeling which announces to us sorrowful or alarming tidings, may be said, like the prophecies of the weird sisters, to come over us like a sudden cloud. During the fatal day which was to precede the combat of the Caesar with the Count of Paris, there were current through the city of Constantinople the most contradictory, and at the same time the most terrific reports.

Some said that the barbarians from the borders of Thracia, the Hungarians, as they were termed, and the Comani, were on their march from the frontiers to surprise the city; another report stated that the Turks, who, during this period, were established in Asia, had resolved to prevent the threatened attack of the crusaders upon Palestine, by surprising not only the Western Pilgrims, but the Christians of the East, by one of their innumerable invasions, executed with their characteristic rapidity.
