more frequent when a more numerous population of both colours shall be crowded along the neighbourhood of the slave-line? And may not the heart-burnings and provincial pride, now manifest, be wrought up to a higher pitch at a period, perhaps not far distant, when the United States will become confident of a degree of strength that cannot require such a {167} complete co-operation as heretofore in repelling the attacks of foreign force? If the slave-holding party persist in the extension of the abuse, it would well become them to give up their constitutional claims for calling forth the militia of northern states “to suppress insurrections,” and for protecting them “against domestic violence,” so far as slaves may be the future disturbers of the peace. Whether they make such a fair concession or not, it is for them to reflect whether their northern neighbours, who have so uniformly and so wisely opposed the evil, and who have so humanely laboured to eradicate it from amongst themselves, will be willing to imbrue their hands in the blood of the injured people who have never excited any of their feelings except pity. So long as the Missouri question remains unsettled, a hope may be entertained that liberal sentiments may prevail. The northern people seem to be almost universally in favour of the restriction, and a part of the finest feelings, and the brightest talents in the Southern States, are ranged on the side of humanity. FOOTNOTES: [86] Benjamin Rush (1745-1813), a signer of the Declaration of Independence and member of the state convention of 1787, was the most eminent American physician of his day, and by his theories regarding the nature of yellow fever won recognition abroad. Serving as physician-general in the Revolutionary army, for twenty-nine years surgeon in the Pennsylvania Hospital, and throughout his life a practicing physician, he nevertheless found time to become identified with many public measures, notably the abolition of slavery, and the extension of public schools, and was a member of nearly every important literary and philanthropic society in Philadelphia. John Redman Cox (1773-1864) was, like Rush, a Philadelphia physician, being trained at the University of Edinburgh. He was for many years professor of chemistry at the University of Pennsylvania, and edited several medical journals; but is best known as an early and pronounced advocate of vaccination.--ED.
