The biographer presents Washington Irving as an attendant at the famous trial at Richmond, where his indignation at some of Burr's privations are expressed in a most interesting letter. This sympathy is the more touching from the fact that Washington was a Federalist, and in this respect differed from his brothers. We have an idea that his youthful politics were in no small degree influenced by those of that illustrious personage for whom he was named. Another of the sons was John T., who became a successful and wealthy jurist, and for many years presided at New-York Common Pleas, while Ebenezer was established in trade at an early day. Such was the development of that family, which in rosy childhood followed William Irving to the old Brick Church, and whose early progress he was permitted to witness. The biographer passes lightly over the scenes of boyhood, and there was hardly any need for his expatiating on that idolatry which surrounded the youngest. He was no doubt the first child ever named after the father of his country, and the touching incident of Lizzie's presenting the chubby, bright-eyed boy to Washington, is hit off in a few touches. It was, however, in itself a sublime thing. Nearly seventy years afterward, that child, still feeling the hand of benediction resting upon him, concludes his _Life of Washington_ by a description of his reception in New-York, of which he had been a witness. Why does he not (it would have been a most pardonable allusion) bring in the incident referred to above? Ah! modesty forbade; yet, as he penned that description, his heart must have rejoiced at the boldness of the servant who broke through the crowd and presented to the General a boy honored with his name. Glorious incident indeed! As the family grew up, the young men took to their different professions, which we have briefly designated. Peter read medicine, and hence received the title of 'doctor;' though he hated and finally abjured it, yet, as early as 1794, he had opened an office at 208 Broadway. This, however, was more a resort for the muses than for Hygeia, notwithstanding its sign, 'Peter Irving, M.D.' In 1796, William Irving, who had been clerk in the loan office, established himself in trade in Pearl--near Partition--street, and from his energy and elegance of manners, he became immediately successful, while farther up the street, near Old Slip, John T. opened a law office, which was subsequently removed to Wall street, near Broadway. We mention these facts to show that Irving entered life surrounded by protecting influences, and that the kindness which sheltered him from the world's great battle had a tendency to increase his natural delicacy and to expose him to more intense suffering, when the hand of misfortune should visit him. One who had 'roughed it' with the world would have better borne the killing disappointment of his affections; but he was rendered peculiarly sensitive to suffering by his genial surroundings.
