The success of even professional men depends in no slight degree on their physical health; and a public writer has gone so far as to say that “the greatness of our great men is quite as much a bodily affair as a mental one.” {319} A healthy breathing apparatus is as indispensable to the successful lawyer or politician as a well-cultured intellect. The thorough aëration of the blood by free exposure to a large breathing surface in the lungs, is necessary to maintain that full vital power on which the vigorous working of the brain in so large a measure depends. The lawyer has to climb the heights of his profession through close and heated courts, and the political leader has to bear the fatigue and excitement of long and anxious debates in a crowded House. Hence the lawyer in full practice and the parliamentary leader in full work are called upon to display powers of physical endurance and activity even more extraordinary than those of the intellect,—such powers as have been exhibited in so remarkable a degree by Brougham, Lyndhurst, and Campbell; by Peel, Graham, and Palmerston—all full-chested men. Though Sir Walter Scott, when at Edinburgh College, went by the name of “The Greek Blockhead,” he was, notwithstanding his lameness, a remarkably healthy youth: he could spear a salmon with the best fisher on the Tweed, and ride a wild horse with any hunter in Yarrow. When devoting himself in after life to literary pursuits, Sir Walter never lost his taste for field sports; but while writing ‘Waverley’ in the morning, he would in the afternoon course hares. Professor Wilson was a very athlete, as great at throwing the hammer as in his flights of eloquence and poetry; and Burns, when a youth, was remarkable chiefly for his leaping, putting, and wrestling. Some of our greatest divines were distinguished in their youth for their physical energies. Isaac Barrow, when at the Charterhouse School, was notorious for his pugilistic encounters, in which he got many a bloody nose; Andrew Fuller, when working as a farmer’s lad at Soham, was chiefly famous for his skill in boxing; and Adam Clarke, when a boy, was only remarkable for the strength displayed by him in “rolling large stones about,”—the secret, possibly, of some of the power which he subsequently displayed in rolling forth large thoughts in his manhood.
