In France, a third attempt is made to assassinate the emperor--this time by Orsini, an Italian; it appearing that the plot had been hatched in England, great indignation prevails in France, and a remonstrance is addressed to the British government, urging it to make stricter laws against political refugees. Lord Palmerston introduces a bill for this purpose, and upon its rejection by the House of Commons he tenders his resignation. The Derby ministry is installed. The Livingstone expedition sails from England for Africa. The Princess Royal is married to the Crown Prince of Prussia, afterward Emperor Frederick III.

In China, the treaty of Tientsin with Great Britain, France, Russia, and the United States checks the allies' advance on Peking.

Petroleum oil obtained in Pennsylvania by method of boring wells. Silver discovered in Nevada. Harper's Ferry, Virginia, and United States arsenal captured by a force under leadership of John Brown, his purpose being to hold the place as a refuge for fugitive slaves. Brown is besieged by citizens, State militia, and Federal marines; makes stout defense, but is captured, tried for treason, and executed. Sympathy mingled with reprobation in the North and alarm in the South over John Brown's act; his execution arouses indignation among the abolitionists and helps to precipitate approaching national conflict over slavery. Washington Irving, American author and diplomat, the first to win foreign recognition for American literature; Prescott, American historian; Rufus Choate, American lawyer and orator; and Horace Mann, American educator and statesman, died.
