We have not written of Dr. Haddock as a politician; but he is a thoroughly informed statesman, profoundly versed in public law, and familiar with all the policy and aims of the American government. He is of course a Whig. He has been educated, politically, in the school of his illustrious uncle, and probably no man living is more thoroughly acquainted with Mr. Webster's views, or more capable of their application in affairs. It is therefore eminently suitable that he should be on the list of our representatives abroad, while the foreign department is under Mr. Webster's administration. The Whig party in New Hampshire have not been insensible of Dr. Haddock's surpassing abilities, of his sagacity, or his merits. Could they have done so, they would have made him Governor, or a senator in Congress, on any of the occasions in many years in which such officers have been chosen. Considered without reference to party, we can think of no gentleman in the country who would be likely to represent the United States more worthily at foreign courts, or who by his capacities, suavity of manner, or honorable nature, would make a more pleasing and desirable impression upon the most highly cultivated society. Those who know him well will assent to the justness of a classification which places him in the same list of intellectual diplomats which embraces Bunsen, Guizot, and our own Everett, Irving, Bancroft and Marsh.

The researches of no antiquary or traveler in modern times have excited so profound an interest as those of Austen Henry Layard, who has summoned the kings and people of Nineveh through three thousand years to give their testimony against the skeptics of our age in support of the divine revelation. In a former number of _The International_ we presented an original and very interesting letter from Dr. Layard himself, upon the nature and bearing of his discoveries. Since then he has sent to London, where they have arrived in safety, several of the most important sculptures described in his work republished here last year by Mr. Putnam. Among them are the massive and imposing statues of a human-headed bull and a human-headed lion, of which we have engravings in some of the London journals. The _Illustrated London News_ describes these specimens of ancient art as follows:
