Whatever theory of instinct may be finally fixed upon as the most correct and philosophical, (to account for the migratory movements of birds,) it is obvious that we cut rather than untie the gordian knot when we talk of the foresight of the brute creation.  We might as well talk of the foresight of a barometer.  There can be little doubt that birds, prior to their migratory movements, are influenced by atmospherical changes, or other physical causes, which, however beyond the sphere of our perceptions, are sufficient for their guidance.  That they are not possessed of the power of divination may be exemplified by the following instance.  The winter of 1822 was so remarkably mild throughout Europe, that primroses came generally into flower by the end of December,—­rye was in ear by the middle of March, and vines, in sheltered situations, blossomed about the end of that month,—­so that an assured and unchecked spring was established at least four or five weeks earlier than usual;—­yet neither the cuckoo nor the swallow arrived a single day before their accustomed periods.  They are indeed, beautifully and wisely directed,—­“Yea, the stork in the heavens knoweth her appointed times; and the turtle, and the crane, and the swallow, observe the time of their coming.”—­(From a delightful paper upon American Ornithology, in the Quarterly Review, just published.)

STATUE OF MR. PITT.

[Illustration:  Statue of Mr. Pitt.]

This splendid tribute to the memory of the darling minister, has been placed at the south side of Hanover Square.  It is of bronze, and stands on a granite pedestal, of size disproportionate to the height and bulk of the figure.  The artist is Mr. Chantrey:  the work being at the cost of the nobility of the land, and a few ardent admirers of “the system” introduced by Mr. Pitt into the government of this country.  We have long had festal celebrations and joyous commemorations of the natal day and deeds of the minister—­“the darling of fame”—­but the above is the most lasting memorial.  Its bronze will in all probability outlast the mettle of party.  The resemblance is considered striking, and the effect of the statue is bold and dignified.  Biographers tell us that “in person, Pitt was tall, slender, well-proportioned, and active.  He had blue eyes, rather a fair complexion, prominent features, and a high, capacious forehead.  His aspect was severe and forbidding; his voice clear and powerful; his action dignified, but neither graceful nor engaging; his tone and manners, although urbane and complacent in society, were lofty, and even arrogant, in the senate.  On entering the house, it was his custom to stalk sternly to his place, without honouring even his most favoured adherents with a word, a nod, or even a glance of recognition.”
