receiving a modified permi ion, he set out without waiting for a summons, and an angel, visible only to the a that he was riding, barred his path. What ensued is recounted in Numbers xxii. to xxiv. Balaam, with the sanction of God, arrived at Kirjath-Huzoth, Balak’s capital, but instead of cursing the Israelite host, was constrained to ble them three times. He returned to Pethor, after advising Balak to use the Moabite women as an instrument for leading the Hebrews into idolatry. Moses at God’s bidding then took up arms inst the insidious foe, and in the battle that followed Balaam was slain. Balena. [WHALE.] Baleniceps.

The general for the accuracy and delicacy of a are: (1) the beam should be horizontal the pans are unloaded, a condition generally by a small screw adjustment; (2) the arms the balance should be of equal length, otherwise load at the end of the longer arm will counter a heavier load at the other end. The error by this inequality may be removed by the body in each pan separately, and then the square root of the product of the two; thus, if the object counterpoise 3 grms. one pan, and 3:1 in the other, its true ma will./3x3:1.

This requisite is very important, and to satisfy it the beam should be light, the arms as long as po ible under the circumstances, and the centre of gravity of the beam should be close to the point of support. But this condition satisfied, the beam takes a long time to come to rest, oscillating slowly backwards and forwards to each side of the mean position.

The Thirty Years’ War was partly waged in its defence, as well as in that of Protestant ism, and it was a prominent factor in promoting the various coalitions against Louis XIV., and the alliances of the various nations of Europe against Napoleon I., while at the Congre of Vienna in 1815 the map of Europe was reconstructed with special reference to its maintenance. Of late years, since the growth of the doctrine of NON-INTBERVENTION (q.v.), it has fallen into some disrepute in England.

Thus, when value of exports exceeded that of imports the of trade was said to be favourable. This is best set forth in Thomas Mun's dngland’s in Foreign Trade (1685). ‘To maintain a balance-—usually by prohibition of the of specie and by high import duties—was the object of the policy of every European state Adam Smith showed in the Wealth of Nations a reserve of specie was not nece ary for the conduct of a foreign war, and that, in the wealth exported to pay for recent wars had the form, not of specie, but of manufactured The English Government had remitted the required by bills which it purchased, and the rise of the premium on foreign bills had the export of goods against which such could be drawn. In recent times the term “unbalance of trade” has been chiefly used reference to the relation between imports and As “ exports pay for imports,” owing to invention of bills of exchange and other substifor coin, it would seem to follow that if imalways largely exceed exports in value (as is case with regard to the United Kingdom) the must be somehow paid for out of the national a proce which must eventually result in bankruptcy.
